I would think it's the best dual flush on the market.
I have sold 263 of the Aquia toilets, and have only had one returned for replacement.
99+% still in service.

Toto Aquia dual flush toilet

I have had the Aquia installed for about 10 days. It is much better than its Australian counterpart --- cleans the bowl well and flushes great. Even the 1/2 flush flushes a bit of paper. The waterspot is very small...it is, of course, a washdown design. The only disconcerting thing is that the design of the trap is such that you can hear urine running down the drain when urinating, at least in my house.

It does use the plastic trapway that is open to the back.

I can see that there will be more noise with it.
However, after looking at it in the showroom, I'm looking forward to selling them.
It looks nicer than the Caroma and it comes in the elongated bowl, which I like.

Teflon tape,
Do you have pictures you can send me of it?

I saw this in a showroom and was surprised at just how exposed the plumbing was in the back--too much for my taste. The picture above doesn't really give a good sense of that.

Terry

We're considering this toilet (and the Caroma) for a bath remodel, and we have small children in the house. I haven't seen this toilet locally yet (I'm in a fairly isolated area in CA), so any way someone could post pictures of the plastic trapway open to the back?

In one picture it looks installed very close to the wall -- 3 - 4" maybe? So you wouldn't really see the trapway unless you were on the floor, wedged behind the toilet? Enquiring minds....

Could you possibly retrofit it with insulation? Does the trapway need to be exposed? If we insulate the wall behind the toilet well, I'd assume that would eliminate some of the noise -- at least to other rooms.

Also, Terry, what about it "looks nicer" than the Caroma -- would you be able to be more specific on that point? ie. Modern, stable, cleaner lines, durable?

We're specifically interested in a DF model, and have all but eliminated the Sterling (Kohler) Carsten model http://sterlingplumbing.com/onlinecatalog/color_price.jsp?rescom=professional&item=4386903
based on the MaP testing, and various comments gathered from your site. Even though initially, I really liked the looks of that toilet design. I suspect I'd be falling into the homeowner trap of choosing form over function -- not a good option for a critical fixture such as a toilet. ;)

Really, really appreciate your website, information and boards!

Thanks much,

Lisa

Most of the unifit Toto's (if not all) are open to the rear. Unless you use a mirror, you can't see into the back (well maybe if you are a wet noodle). The skirt basically blocks any view of the insides from the back. I don't see the problem...

I just bought a used home. I had three toilets to replace the same day I moved in. I just had to get rid of the old stuff.

I just installed the Toto Aquia in my main bathroom.
It looks great and flushes very well.
It looks so nice, it's almost like the bathroom has been remodeled.

The downstairs bathroom now has the Sanagloss Ultramax.

The third bathroom gives me some room to do some testing with.
That will be the room where new products will move through pretty quckly.

I've had the Aquia installed for several months now, and I still catch myself admiring it when I walk by. Many of my guests also comment on how it's like the modern toilets they commonly see in europe. The thing about the waterspot is this - the toilet is pretty much designed around it. In other words, solids tend to drop straight down into it, avoiding the contact and staining that would result in other toilets. And of course, whenever you would normally need a courtesy flush, you would probably need one with the Aquia as well, so this should cut down on the excessive stinkiness you are afraid of. I've also noticed that any stains that do show up usually get washed away during the refill. If not, a second flush almost always cures it. Overall, I am extremely pleased with this model.

Thanks for the reply. I guess we were scared to use it for a while because I was the one that installed it and we wanted to make really really really sure it was done right and would not leak.
I do think that folks who sell this unit should strongly warn/caution potential owners about the water spot size. I bought mine from a real lumber yard with a real plumbing showroom from the manager of the showroom. They sell so many of these toilets that they had a ton of them in stock-yet not a peep from him about the toilets unusual characteristics. If he just would of warned me that the small water spot size was normal and yes it does work great that would of killed all my fears right there (well most of them).

My sister-in-law was visiting the US for the first time from Australia. All the toilets "back home" have small water spots, typically a dual flush design (they've been very concerned about water conservation for many years, so it's been a common feature for the past 20 years in Australia).

So, my sister in law gets to the US at LAX, and has to stop an use the toilet. Goes in, and it looks to her like the first bowl is flooded -- the water is *way* up from where she's used to seeing it. Second bowl, same way. She checks every stall, then runs to the nearest Airport personel, yelling about the state of their bathrooms, and how every toilet is backed up. She's absolutely freaked out about how much water is in every toilet. Only when the poor airport person goes into the toilet with her, flushes it in demonstration does she calm down.

That was 3 or 4 years ago, and she still tells this story about the toilets in America.

The relevance to this thread is that you'll probably get used to it, and then regular toilets will start to look flooded to you! ;)

-- Planning to install 3 new Aquia in my house in the next few months. Thanks to all the great information in these forums.

Hi Lisa,

Yea we are used to it now. I especially like the soft close lid. I thought it was just an expensive gimic but now I like it.
Similar story to yours. A good friends FIL who is from Italy is visiting right now. First time he used their standard toilet he was shocked at how much water was in there and upset that there was a lot of 'splash back' when he was using it...

The installation of the 2 Acquias I bought was a lot more difficult than expected. Luckily for me, they were installed on the 2nd floor, so even though some more holes had to be drilled in the floor tile in one bathroom, there wasn't a slab underneath -- that would have required some serious drilling! We had a height limitation of 30" under a shelf that is an extension of our vanity top in our powder room (which is on slab), so we ought an Ultramax elongated for there. That installed in no time flat. Beware that the Acquia needs 6 holes in the floor to install!!

jadnashua

Oftentimes, drilling into concrete is much easier than through tile...and, with Toto's, that model, and any with the unifit adapter require additional holes in the floor to install.

We had an Acquia installed last month as part of a total bathroom remodel.
We had a plumber do the installation, so I can't really address the ease of installation issue -- but we love the toilet. I know that sounds weird. But the thing it replaced sometimes needed to be flushed a couple of times even for #1, and the Acquia handles whatever we put into it with style and aplomb.

I really like the skirt; it just looks so much cleaner. I was worried about the small water spot, and the fact that some other folks had complained (either here or at another site) about smearing, but we've had no problems. The small flush setting is very complete, and the big flush setting even more so.

One thing I haven't seen mentioned is how comfy the soft-close seat is. Again, this sounds a little weird, but the seat is shaped really well to fit my tush.

I would agree with your comments on the looks and comfort of the Aquia toilet. We have had one in the hall bath for about ten months. My old American Standard would get clogged at least once a week, but since we changed to the Toto it hasn't clogged at all. I plan on changing my other 3 toilets to the Toto brand. I picked the Toto brand from recommendations on this website. Thanks Terry!

what are the 6 holes or extra holes? The spec sheet only shows the standard 2 bolt holes?

Notice the screw cover down low, closer to the wall.

In addition to the two closet bolts, the adapter is held down by two more points at the back, closer to the wall.

There are also two blocks near the wall that use two screws each.
These are for the side mounted attachment screws with chrome covers.

That makes a total of six holes that would be drilled in tile.

Gotta agree about how pleased I am with the Acquia. Comfy (love the ADA height), flushes incredibly well, and is usually clean (although I keep a small brush set next to each toilet just in case). We've had them since February and have them in 2 bathrooms -- master and hall used by a teen. ONCE in all this time I had to flush a 2nd time -- and that's using the .9 gal -- twice with this is still waaaay less water than the multiple times I had to flush with the old toilets. We bought them just before our water district's voucher program ended -- saved $165 PER TOILET (we saved only $75 on the Toto Ultramax we needed for the powder room due to counter height restrictions -- otherwise would have used another Acquia). Love, love, love these toilets (and love confounding guests, LOL). Only complaint about the slow close seat involves "husband training" -- if he leaves it open, I need to wait for it to slowly close before I can use it.....he needs to be retrained, LOL.

I am seriously looking at putting these toilets in a new home I am building. The one concern I have is about the flush buttons. I have long fingernails and when flushing cannot use a fingertip to flush as most would.

Do the buttons stick up enough that you can use your finger about where the top knuckle is to flush without a problem or do you have to really push down into a recessed area to flush these toilets?

Peanut9199
05-28-2007, 10:45 AM
The button is a circle the smaller side for 3 litre and the larger for 6 litres.
It pushes into a channel, you can use a knuckle to push but both will go down as the smaller side is to small to fit just a knuckle.
Hope that helps?

I concur, knuckles are a little too large to press just one button.

Any comment on the noise level when you flush Aquia???:confused:

It would be nice if there is a section about noise level for different toilets...Similar to the Maximum Performance rating done by veritec... All one need is a noise meter... Of course... it should be a controlled setting... like same plumbing or preferably same room...

P.S. Gotta love this forum... I believe no where else can you talk about toilet with such detail... Thanks Terry for opening such a forum...

A section about jokes & toilet humor would be a nice addition... Just for the fun of it...

Toto Aquia CST414M with SS114 seat.

I found your website very helpful in deciding which toilet to purchase. We decided on the Total Dual Flush which we're very happy with since it was installed 3 days ago. But I have 2 questions and a comment. One question--is it necessary to use the larger flush for solid waste? The .9 gal flush is effective, but do we risk having the solid waste clog up the pipe along the way to the sewer?

The comment is that, for readers who are not remodeling their bathrooms, be aware that the "footprint" of the new toilet is different from that of the old one. In one bathroom, the formerly-hidden linoleum looks stained and in the other bathroom, we're left with an unsightly white dried putty-like substance. Is there some product that will dissolve that? Otherwise we'll need to replace the linoleum. Had we known that that could be a problem, we would have planned to replace the linoleum at the same time as the new toilet was installed.

On another note, some people drop a square or two of tissue in the bowl first. It keeps the bowl clean, and prevents any splash.

You can usually remove the dried putty or caulking by scraping with a putty knife. Pain thinner will soften it if nessesary.

Installed a Toto Aquia yesterday.

I am not a plumber. Have removed and re-installed one toilet until this week!

The installation is different than most but not difficult. Admittedly, mounting on ceramic tile or concrete would present drilling problems that I did not encounter on wood. However, paper template is provided and allows for easy alignment of mounting blocks and plastic adapter/trap. Instructions provided are good but not perfect. Recommend that you read them completely before starting to get an idea of the whole process.

Suggestions when installing:
Bowl... Instructions state to slide the bowl into the adapter/trap until it touches the wall. I would leave at least 1/4 inch between back of bowl and wall. Instructions for attaching tank contradict that by warning against tank touching wall! Back of bowl aligns with tank so to keep tank from touching wall the bowl should not touch the wall either.

Tank... Installation requires careful even tightening of the two brass fasteners to avoid slow leaks. If leak occurs, remove tank and make second attempt to tighten evenly. Be sure to place tank to bowl gasket fully on the bottom of the tank to prevent leaks there too! The flush mechanism was set at 7 litres. Be sure to set it to 6 litres.

Footprint issues...
I installed a Caroma One-piece EL ADA the day before the Toto Aquia.
Somewhat easier to install due to one piece construction. Aquia has a shorter footprint than many toilets, and the skirt tapers at the front. It would not cover the footprint of old toilet in master bedroom ensuite bathroom without extra flooring work. Caroma covered it easily! Similar footprint issue exists in main bathroom so another Caroma will go in there.

Aquia looks great installed in the main floor powder room which did not have the footprint problem.

Performance...
Cannot say much about performance of these toilets due to short time they have been in use. They both flush well, fill fast and you will probably have to get used to brushing after use. I would rather brush than plunge clogs or deal with overflows. The old Crane toilets sometimes had to be snaked to clear them! They often had to be double flushed and they used more than the previous "standard" of 13 litres per flush! Based on the research I did before purchase I believe I can get rid the plungers and the snake too.

I noticed that both the Aquia and the Caroma make the same noise when the half flush is used. "Thunk" can be heard just as the flush finishes. That noise is not present when full flush is used.

We have plenty of TOTO Aquia toilets for the Seattle area now.
We just picked up 40 of them.

I must say that installation took me 2 hours. This is the 1st toilet I have ever installed so it was a slow go and the directions aren't the best at all.

OK so I came back to give my evaluation.
I still fume on how horrible the installation was. I even called Toto with no call back after I was on hold forever and left a message.

Overall so far I like the toilet. I have not seen the leaking problems. Maybe I used the magic tightness so it didn't leak on me, but I have no clue what that is or was.

I can echo a lot of the common complaints. Small water spot & tank cover not attached.

I have found for the most part the .09 flush will also work for solids. If anything is left it is mostly paper.

I do not like the bolts used to attach the seat. I cannot get them tight so the seats slides a little on the base when you sit down.

Oh I do find its not very easy to clean the toilet at the very bottom of the inside of the bowl. My water has some sediment and it leaves a brown film where the water trickles after flushed and in the bottom where the water sits. I know its my water but the curve at the bottom makes it difficult to get the brush in there easy. I might need a smaller brush.

Overall I think this is a good first try for Toto. Some improvements can be made and hopefully soon since these seem to be getting hotter. I have 2 more to replace in my house but I'm going to wait until Toto comes out with another model or I see some other manufactures.

Oh I can't really say if my water bill has went down yet. I have only got 2 bills since I installed and they were down $5 but I don't know from where.

I just installed two Toto Aquia toilets in my home because my local water district will give me $150.00 for each one. The comments about the instructions not being the best are correct, but carefull scrutiny and common sense will get you through. I have a few tips that may help. The big screws that hold down the mounting blocks are real pieces of ****! Do yourself a favor and get either the same size screw (1/4"x2 1/2") with a phillips head or even a lag bolt of the same size. I stripped two of the screws installing the first toilet and had to raid the hardware on the second to finish the job as it was New Years Day and nothing was open. I enlarged the pilot hole slightly and was able to get the screws in. On the second toilet I used lag bolts with a socket on my drill and had them tight in seconds, and no blisters!
When attaching the tank you really have to crank that sucker tight. This was hard for me because in my experience with toilets you snug bolts up just enough to avoid cracking the porcelain. After the first toilet was in I spent lots of time feeling around the base for leaks and was happy to find none (or so I thought). I was feeling good after getting the second toilet in untill I noticed water on the floor. I contorted myself around to start feeling where the leak was and finally figured it was the tank bolts. I tightened them up, but was still unsure if they were water tight so I used a paper towel and slipped it between the tank and bowl to check for water. Sure enough the towel came out wet, this was residual water from the leak so I used the towel to dry it up and then another to see if water was still leaking. It took several times tightening the bolt to stop the leaking, but I really had to put my back into it to get the bolts tight. Fortunately nothing broke. I then went back to the first toilet and used the paper towel technique to check for water and sure enough I needed to tighten those bolts as well.
When sliding the tank onto the plastic base, wet the rubber first and the tank will slide on easily. Same thing with the rubber seat bolt anchors.

I have also just installed the same toilet just last night. It seems that most forums I've read about this toilet state exactly the same complaints about the install (poor instructions, wrong drill bit sizes, leaky tank to bowl connections) and some of the questionable performance features. Most of it was true with my installation experience however it is a pretty sharp looking toilet! (Seems a bit strange to say that! haha)

However, I am having the same problem with the leaky tank bolts. I've tightened the bolts down fairly tight and there seems to be an acceptable bit of play in the movement of the tank (ie. 1/4-1/2"). One other poster had suggested tightening the bolts to the point where the tank hits the stops on the toilet. That seems awfully excessive!? (Maybe it's not- honestly I don't know) I was wondering if some plumbers putty or silicone might be a better solution? Seems to be a mixed opinion on that.

It's my first bathroom DIY. Any suggestions would be appreciated.

We sand the inside of the tank where the bolt connections are.
The bolts should be as in the picture, with the rubber near the tank, then the washer, then the bolt.
We normally rotate the flush valve out while we tighten, and replace when done.
The bolts need to be turned bit by bit, side to side. In otherwords, evenly.
We install these all the time, and it's just a matter of slowing down.
We don't use anything on the rubber washers.

Plumbers putty will cause leaks

From what I think I gather, most of you have installed in new construction. Has anyone had any experience with installing one of these toilets in an old house with the old cast iron waste lines? If so how well has it functioned?

I have just about made up my mind about this toilet but have a very quick question. When the toilet is installed with a 12" rough-in, how far is the back of the tank away from the wall?

My existing toilet RI distance is 12" from the baseboard. So add perhaps an additional 1/2" to account for that. However, the back of my tank is 2" from the wall. These toilets were installed about 10 years ago. Is it just likley they used a toilet with a 10" RI and the plumber assumed a 12"? Was a 10" RI standard 10 years ago? Most of the stuff they installed in this place is off the shelf at Home Depot.

Trust me when I say the previous owners have found a way to screw up just about everything else in this house so the toilet is unlikely to be an exception!

Thanks

Terry
02-25-2008, 01:12 PM
The rough-in is measured from the wall, not the baseboard.

At 12", the Aquia would have about 1/4" from the tank to the wall.
If you have 12" to the molding, then add for the molding too.

riverdale

Great, thanks for the information. I am ordering mine today.

Now, just one more thing. I was initially concerned about the Aquia being an unlined tank. I am in Southern Ontario and it gets rather humid here in the summer. I have read elsewhere that tank sweating isn't a huge problem with "modern" water saving toilets as they don't completely empty the tank. Thus the fresh cold water is mixed with some remaining room temp water preventing, or at least significantly reducing, any sweating issues. Any one have any comment on this aspect of the Aquia specifically?

Thanks again.

The Aquia uses just some of the water in the tank. I don't think it will sweat. Terry

Hello. I just installed a new Aquia for my powder room. The flush valve does not shut off completely and water keep dripping out of the tank to the bowl evan after the tank is filled. As water keep dripping from tank to bowl and thus the flush valve keep dripping to refill the tank. This turns into a water wasting cycle. I checked and made sure the bolt from tank to bowl installed correctly as there no water leakage on the exterior of the toilet. I cleaned out the flushvalve and the flushing mechanism as instructed in the instruction manual. However, it did NOT solve the problem.

Is the flush valve and/or the flushing mechanism main cause of this problem? If so, can someone advise on how to adjust them?

Thanks in advance.

Installed ours today, went "slow and steady" and so far all is well. Have been a "lurker" for the past couple weeks, thanks to all posters for the good advice!

Great website Terry!

DQH98 - sounds like a flushing valve issue, but am certainly not an expert, hope your supplier can help. Our's drips for about 5-15 seconds after using it.

Neat toilet, very impressed with the amount of flushing action given the small amount of water used. Kids enjoy using it, they actually bypass the other toilets in the house in order to use the toilet "with the buttons".

Well we have had ours in place for 6+ weeks and I have yet to pick up a plunger! AWESOME. This in a house of 5, where someone would clog the toilet at least once a day, no exaggeration.

Almost all issues (#1 & #2) are taken care of with the "small" flush. Yes there is the occasional streak, but I would say less than with our old toilet. Most of which gets taken care of when the toilet gets flushed and the bowl fills substantially with a forceful torrent of water. The water spot is perfectly placed to catch most of what goes in. A "normal" toilet looks ridiculously wasteful and/or clogged when you get used to looking at such a tiny water spot as in this toilet.

The install is a little more involved than a regular toilet, especially if you have tile floors, but nothing a half competent DIY'er can't handle.

There is a slight whoosh/thump on flush but minor when the lid of the tank is on etc. I certainly isn't waking the whole house up if you flush at 2:00 a.m.

First thing we noticed after this toilet was in is the lack of "outhouse" smell in the bathroom. Three boys in this house and it seems when they miss it would drip down through the bolt holes for the toilet seat and then onto the ceramic surrounding the flange. It would always smell no matter how often this got wiped up. This has been totally eliminated with this toilet. I presume because of the excellent rubber seal between the seat and bowl.

Looks fantastic, easy to clean, inside and out, saves huge amounts of water, overall a 10 out of 10. We ordered a second one for our basement bathroom two days after we put this one in. We will also be using one in a third floor masterbath once the addition gets built.

Hi,
I just finished inmstalling a Toto Aquia Dual Flush Toilet. Many thanks to this forum and it's users for sharing their insights on the toilet and it's installation. I have only every installed one toilet before so I was very anxious about getting this done right.
Once I removed the old toilet I had quite a job removing the old silicone. I had to restain the hardwood underneath where the old toilet was as the new one has a different foot print. I marked the holes with the template and predilled with the 11/64th bit. I installed the PVC trap and screwed it to the floor. I took the advice of another member and used 1/4" x 2 1/2" Lag Screws to secure the mounting blocks to the floor.
I installed the bowl all the way to the wall which I realized after that I should have left a 1/4" gap. Once the tanks was connected it was touching the wall so I had to go back a few steps to try and pull it back off of the wall. Once the bowl and tank were secure we added the water and we only had a slow drip at angle stop. Once that was tightened up we seemed to be good to go. We adjusted the water level on in the tanks and adjusted the half flush too.
Everything seemed to be going great until I sat on it wobbled.
I tried adjusting the base screws with no success. At this point do I just shim it was a coin or two or do I need to take the whole thing apart and start over?
Will the silicone seal help stabalize the toilet too? Should I shim and seal it?
Any thoughts would be appreciated.
I will post some photos too.
Thanks a lot for this great forum and site Terry!

We use the composite shims from HD.
We buy them by the case.
They have a thin taper to them, snap off easily and wear well.

First, I'd like to thank Terry and all of you for your comments and recommendations - they helped me not make any mistakes while installing the toilet. Things I learned this time 'round:

1) The composite shims are located in the windows and door section of Lowes. The plumbing gents will look at you like you are asking for a left footed screw driver.
2) Use a paper towel plug to keep the sewage gas out of the house. If you forget to pull it out before installing the rough in, one flush and it moves along, unlike the plastic bag I used several toilet installs ago.
3) If you are installing on a tile floor, the blue granite bits by Bosch work wonders.
4) The white screw anchors are a joke. Even if you drill 5/16" holes. I knocked mine in as far as they would go and then cut off the tops with a hacksaw blade. (It helps to rub a bar of soap on the screw threads to lubricate them and make it easier to thread in, TL)
5) If the location of one of your holes is near the edge of the tile on your floor, the tile will very likely crack when installing the screws. Not sure how to get around this unless you drill a bigger hole in the tile.
6) Duct insulation or a bit of hot water heater blanket wrapped around the plastic rough in quiets things up a fair bit.
7) I didn't have leakage from the tank bolts, I had leakage from the filler tube. Props to Terry for letting us in on the sand the tank trick - it worked great.

All in all, only a little more time consuming than installing the American Standard that lives in the downstairs basement. Wife hates that toilet because of all the grooves and crevasses it has.

Just had Toto Aquia installed by plumber yesterday. One question so far: flushing by pushing either button does not empty the bowl. Is this normal?
The water rapidly wooshes down, but stops at about the level of water that was in the bowl to begin with. When I remove the tank cover and flush with the larger button, the water in the reservoir goes down, but not all the way.
We have the Toto Carlysle in another bathroom, and it empties the bowl when we flush. Haven't tried #2 yet, but note with #1 some residual foam on top of water in the bowl after flushing. Would appreciate any comments from others with experience with this toilet.

jadnashua

If you Carlyle empties the tank, you don't have the right flapper valve in it! Nearly all gravity flush low-flush toilets do not empty the tank - they use the water height to add pressure and a large flapper valve to create a large volume, but cut it off quickly. With a properly designed bowl, that short, intense dump of water pushes the waste past the trap and empties the toilet. The better ones wash the bowl in the process, but that is somewhat a factor with the original water spot.

If the Aquia doesn't flush waste properly, you may have a drain problem.

Looks like the AII has an integrated trapway and the AIII is ADA height and has slightly different styling.

I'm planning on purchasing two AII's in the next month or so-unless I hear bad reviews on this and other forums in the meantime.

Does anyone have an opinion about which is a better toilet - the Toto Aquia or the Caroma Caravell?

I'm glad I found this website!

Our water company is giving a rebate on low-flow toilets and after exhaustive research we decided on the Aquia II. However, instead of a 12" rough-in, my plumber says that the rough in in the master bath is 11 5/8" !
He wanted to know if this toilet might have "wiggle room".
My house was built around 1950 and it's old ceramic tile. I called Toto in Georgia and Customer Service (who was very nice!) said that we could give it a try and see. On the other hand, the Caroma installation seems to have a (shall I call it?) flexible rough in so that it WOULD have wiggle room?
Any experience out there?
Suggestions? Comments?
I am in the San Francisco Bay Area.

07-17-2008, 06:38 PM
Someone elsewhere said that at 12", there is 1/4" of gap behind the Aquia. At 1/8", you can probably make it fit, but it'll be really close. You might put a square up between the wall and floor - if you're lucky, the floor/wall junction is slightly over 90-degrees, and you'd have room.



Or just move the closet bolts to 11-3/4" and make it work, Terry

GramGram
07-21-2008, 11:54 AM
This didn't seem to answer my question. It's that I don't have enough space between the first bolt and the wall. We are going to try a "dry fit" tomorrow and I'll pay the plumber for his time if it doesn't go. The plumbing supply place will take back the Aquia and we'll probably get the Caroma even though the bowl sticks out too far and not enough room to the tub. Sigh!

I am interested in buying the Aquia II or Aquia III next week. I do not need Universal height of Aquia III.
Before buying, I would like to know how Aquia II or Aquia III flushing performance and skid mark creating compares to Drake or Ultramax.

I also would like to know how the Aquia II or Aquia III is installed. Looking at http://docs.hdpi.com/PE-Links/Toto/Toto_AquiaComparrisonChart.pdf , it seems that Aquia II or III do not have the plastic trap like the Aquia. But Aquia II and III do have an "outlet flange". Does the outlet flange need to be screwed in to the floor?

I am presuming that Aquia II and III are installed differently from Aquia. Could not find Aquia III or III install instructions on Toto's site.

Thanks, Terry, for this great forum.

I have had an original Aquia for just over 2 years and I'm generally very happy. It does seem to "mark" more easily than other toilets I've owned. The one problem I wonder if others have had is a mineral buildup. I can generally remove the buildup with some CLR and elbow grease, but it's frustrating that I've had to deal with it. It's likely caused by a habit of not flushing urine to further conserve water (we picked up that habit during a drought last summer). I've asked the family to use the 1/2 flush since the first cleaning, but the buildup seemed to return within a few months.

Anyone have any ideas or suggestions? Thanks.

Aquia and Drake use the same fill valve parts so they would be affected the same.

2 questions:
1) How hard is it to push down on the button to flush? I have seen some of the flushes with buttons on the tank in hotels and they are hard to flush.
2) How easy is it to reach for kids? I don't have much space around the toilet and wondering if anyone has experience with this?

I like the look of the toilet and that most people seem to think it flushes really well.

We have had it in our Men's Showroom washroom for years and we have had all sort of people including children and i have had no one mention trouble pushing the button.
I find it easy to push and you don't need to stand at the side to reach.
The only thing is you need to reach around or over the toilet seat lid.

I just purchased and installed the Aquia II toilet after reading through all the posts here (Thanks Terry for having such a great website). The install took quite awhile since the I had to also install the toto washet I had for over three years (the main valve that comes with the washlet was very tight where it connects to the flush valve). The new Aquia II complements it really well. I was very hesitant when my wife wanted to purchase the toto washet several years back, but now I don't feel as sanitary when i use just toilet paper.

The Aquia II is fully integrated so there's no more plastic trapway that is open to the back. There's only four holes you have to drill instead of the 6 that is with the original model. I didn't have the leaky connection from the tank bolts or filler tube so maybe they fixed it in this model. All in all, a great toilet!!

I have three Aquia II toilets installed in my house. The hardest part was drilling through the tile. Other than that, they were quite simple to install once you figured out the somewhat cryptic instructions. This was my second Toto install as I had installed a Carlyle toilet a few years ago. Overall, I am quite satisfied with the toilets, except for one thing.

The flushing buttons on top do not seem to sit the same on all of the toilets. Of the three, only one has no play in the buttons. On the other two, the buttons are a little more recessed than the third. I found a video of a Carona toilet in AU that has an adjustment for the button height so you can remove the play in the buttons.

Do the Aquia II toilets have an adjustment like this?

If your buttons are recessed you may run into the same problem.

I don't know if the pins are shorter on the two toilets or not... that may be the case. In any event, do you know of a way to adjust anything to compensate for the difference in pin length? That may be what is causing the buttons to look recessed on top of the toilet

Update... I swapped the tops of one of the bad ones with the good one and the pins appear to be the same size. It looks like either the blue and white buttons are not as high in the cylinder or the cylinder doesn't sit as high on the other two toilets. I am hoping there is a set screw or something to adjust the blue and white button height.. I can't seem to find anything.

I wonder if it's just a function of how tight they got the flush tower attachment nut...there's a gasket underneath, and a little bit of give in the rubber bushing (I think, anyways). Depending on the thread pitch, it might not take much...

It seemed to be sized just right and was light enough to have shipped UPS. I do agree that the lack of water in the bowl is a little disconcerting and sometimes (rarely in my experience) requires you to wash the bowl, it seems to handle most of everything that's thrown at it and I've only had it jam up once in two months.

My general contractor seemed to find this a little bit more difficult than other toilets to install, but not really a lot (and it could have been more that it was all new plumbing in a new bathroom). It does have a weird tinkle noise post flush which others have commented on, but nothing really annoying.

Overall, I'm happy with this thought he button is definitely a little difficult to push if you're actually on the toilet and you might have problems if you have long finger nails.

I'd buy one again.

The Aquia II/III installation is simpler than an Aquia I install. The Aquia I installs using a special version of Toto's unifit flange which acts as part of the trapway. But the Aquia II/III units install much like a conventional toilet; they have their own trapway, and they drop into the "outlet flange" which gets bolted on top of the wax ring/floor flange via the toilet bolts. Then the toilet gets siliconed to the floor if movement is a problem.

We purchased the above Toto about 2 years ago . It looks great and works very very well. I do not find it noisy.
We do have a problem and I am wondering if anyone else has had this problem?.

I find that unless I clean the toliet every 2or 3 days, and sometimes each day , there is a distinct urine odor. I am an Interior Designer/ Decorator and I noticed the definite same smell in a client's home recently (she had 2 dual-flush toto's).Upstairs we have a Maxwell
2nd generation toliet we bought 7 years ago and there is no odor problem with it , tho it does not work near as well as the Toto.

I would appreciate comments if anyone else is experiencing this.?I might add I did contact the Toto rep . and they suggested it could be a vent problem , however we have never had this problem before and as I mentioned the toliet upstairs is fine.

The most common problem is that the toilet was not caulked around the base and an occasional miss by the male (young or old) allowed some to migrate underneath. Pull the toilet, clean well, then reinstall with some caulk to keep that from happening. Sometimes a dog or cat can mark the spot as well.

There are some enzymeatic cleaners that can help, but without the bottom being caulked, it may not penetrate far enough or prevent it from happening again.

There's nothing in the toilet that would allow this to happen.

Note, though, that as a two-piece toilet (on the Drake, but true for any two-piece), it's possible to get some accumulation between the bowl and the tank. That would require taking it apart and doing a thorough cleaning and better aim control!

We've run into a "rocking" issue with the 3 Aquia I's installed in our home. The plumber has installed 2 plastic shims under the front sides of the toilet to help with this, but it's not a pretty solution and creates a gap between the skirt and tile floor. Will silicone actually hold the toilet to the tile?

jadnashua
01-06-2009, 09:47 AM
I use coins to shim, and the preferred place is to force the front down, and shim at the back, but either will work. The real goal is to not allow the toilet to rock. The shims should end up entirely under the lip of the base, so that they aren't visible. The bolts really hold the toilet in place, but caulk will both add to that AND seal stuff from dripping down the sides and going under the toilet where it can't be cleaned easily. Because the bolt holes have some slop, the friction between the bottom of the bowl and a smooth tiled floor make it easier to move the toilet around a little, regardless of how tight you make it. Since tile has no give, nor does the toilet, you can't get them super tight, or you'll crack the bowl, especially if you are using shims - the toilet won't bend! So, shims are needed if either the floor isn't perfectly flat, or the toilet bottom isn't. SOmetimes it is one or the other and both is not uncommon with some brands.

We always shim the back of the bowl and push the front down to the floor.
We do not shim the front unless there is no other way.
Coins do not work well.
We use plastic door shims that are six inches long.
They have a much smoother taper and snap off easily.
After that, we caulk with Clear PolySeamSeal.

Thank you for responding to my question. Your answer makes sense . I forgot

At least you have cleared up there being any issue with the toliet.

I have three Toto Aquias ( type I) in my home and they all do the .9 gallon half flush regardless of which button is pressed. All of them flushed fine after I installed them but after a few months they started doing this.

When taking the lid off the tank, I see no problem with how the button pins align with the internal buttons on the flush tower (although they are a bit short as another person mentioned). If I operate the internal buttons without the lid on, sometimes it flushes properly. But sometimes not and I can see the blue cup rise in the flush tower when the full flush button is pressed and this is supposed to happen only for the half flush.

When I remove the flush tower and fiddle with the buttons, both the stopper mechanisms seem to work just fine.

We have very soft water here and there are no obvious mineral deposits.
Anyone seen this problem?

I've got my Acquia II. I've taken out my old toilet (a first). I've tiled the bathroom (just vinyl tiles...the toilet took most of my budget...over concrete). I've been planning on having the plumber install the toilet. However, I'm not sure, having studied this thread, who has the advantage: me, who's studied this thread but never installed a toilet, or the plumber, who's installed thousands of toilets but never THIS kind of toilet. I did ask him about it. He said he'd heard good things. He said no problem, but he knew he was going to have to drill into the slab. It's not his favorite thing to do, but no problem.

Honestly, that's the scariest thing to me...drilling into the slab. What if the holes aren't straight? What if they're off a bit?

I think between the instructions, this thread, and general 'how to install a toilet' instructions, I'm pretty well off.

I wish the instructions were Acquia II specific. I've gone through and crossed out the stuff pertaining to the A I.

One other concern: the tank bolts.
In post 37 of this thread, Terry said that they sand the inside of the tank where the bolts connect. Every time? And why? Make it rougher to get a better seal? Make it less thick?

Others talk about tightening them...a lot. That scares me too. I don't want to break it. But I also don't want leaks.

I'll probably fire away other questions/concerns. Any bits of advice or answers to the questions wedged into my post are appreciated.

The porcelain after casting, will have a little roughness to it. Using some fine sandpaper will smooth it off, making it easier for the gasket to seal without undue pressure. This is true of any toilet...you probably don't need to do it, but it only takes 10-seconds, so why not?

The Aquia comes with a template to show you where to drill your holes. It's not rocket science. A new, nice and sharp carbide drill bit should drill a clean hole fairly easily. One thing I've noticed is that the plastic inserts they include seem to be sized for metric holes, and the equivalent inch-size is slightly small. I've just picked up some made for inch-size. Your results may differ...I haven't installed one for awhile, so don't know if that was a one-time or long-term situation. A hammer drill makes holes in concrete easier, but for 4-holes, not worth the expense unless you will have a use for it later...more tools are always nice! A regular one will work, especially with a new bit. Vacuum out the debris from the hole before you try to insert the fastener.

Installed an aquia ii the last weekend in february, in the main bath, and unless the the performance starts to "crap" out another will be installed in our 3/4 bath this summer or fall. The installation over vinyl went very well, no runs, no drips etc... Took about 2 hours as i kept reading the instructions and checked everything many times before going to the next step. We have had no issue with "marking", but varing degrees of digestive health could have a bearing on this. A big test on this will be when my brother comes for a visit. We swapped out on old 1940s crane that was a +3 gallon flusher and estimate a 12-15ooo gallon saving yearly on our water bill plus a savings on our sewer bill. While i realize the next install on concrete floor may be more of a challenge i would rate this toilet as moderatly easy to install-looks and performs well and would not hesitate to recommend this unit based on this short period of use.

I had to re-do it this way when a nipple broke on me. Thus the plumbing through the floor is about 3 inches off the wall measured to the furthest edge of the escutchen (sp) and is 2 3/4 inches to the nearest edge of the escutchen from the center of the toilet. If this is too vague perhaps I can attach a picture later. I'm worried that since the Aquia toliet bases run very close to the wall the plumbing will be in the way.
thanks,
Jim

I went ahead and bought the Aquia II and installed it yesterday. There was enough room for the water line that comes up through the floor partially behind the toilet. It is a very nice looking and working toilet. It is also my third (different) toto completing my three bathrooms (thanks to Terry's web site). My advice is to use the link on Terry's responses to Jamie's installation instructions. The part about drilling the white anchors with the 3/16 inch bit is very helpful (always good to switch to a normal wood bit and not use a masonary bit). When drilling on tile I've found it necessary to tap the tile with a nail punch or the bit itself to score the tile so the bit does not walk all over the place. I also thought I would pass on that it is better to use wax to lube screw threads than soap.
thanks,
Jim

I had the plumber do it. I needed some other things done, they were going to be here...I just let them do it.

I really wanted to be here, but couldn't coordinate the schedule of when I was available and when they were. This was probably for the best because I'm sure I would have been hovering.

I'm very happy with it so far.

I'm not sure that the level is set properly for the smaller flush...I don't see a whole lot of difference between the two. (But I'm coming from a 3+gallon flush...so they're both a lot different than that.) I'm going to investigate this weekend.

Thanks to all here.

I've read through the Aquia thread but didn't find an answer to the exact question I have.

I recently removed my Aquia II so I could paint the wall behind it. To remove the toilet I removed the setting bolts and then just pulled the toilet up. It came out extremely easily and cleanly. The bottom of the trapway just popped off the gasket at the outlet flange. So my question is: when I re-install the toilet, can I just set it back on the gasket and bolt it back down, or do I have to remove the outlet flange and put in a new wax ring below?

If it's not obvious, I had a plumber install the toilet so I'm not sure about the proceedure to put it back. From what I"ve been told, you always have to put a new wax ring on, but when I removed this toilet, the connection at the outlet flange seemed so clean, and the wax ring is underneath the flange (which I didn't remove) that I'm wondering if it needs a new wax ring.

If you didn't remove the Unifit rough from the floor, then you do not need to do anything just push the toilet back into the gasket.

We just bought two dual flush toilets and, not having seen the bottom side of the toilet, went ahead and bought two waxless rings to install them. Now that I have seen the system Toto uses I'm wondering if it is possible to use the waxless ring? Anyone done this? How?

How will the waxless work? Do we just bolt the gray plastic plate from Toto to the floor over the waxless insert and then place the bowl over that? We are having a hard time understanding how the red gasket on the waxless system will seal to the gray part from Toto. Are you sure this will work??

We had two Toto Aquia installed 1 1/2 years ago. Now one is constantly running. I followed the procedures for cleaning the flush valve and fill valve, but it seems to be an issue with the float not shutting off the water.

Is there something else I should try before just replacing the fill valve?

Toto is going to recommend the (more expensive) Oval SoftClose seat, SS204.

However, any elongated seat should work for the Aquia series. I would recommend the regular SoftClose seat from Toto. SS114 as shown in the picture Terry posted.

I had an Toto Aquia II installed 'professionally' a few weeks ago. It seems to work fine normally but has leaked twice on me - from the bottom of the toilet, it doesn't overflow through the bowl.
The contractors original blamed it by rough iron pipes. A blockage it not out of the question, but should it be leaking out of the bottom??

Does this sound like a case of a bad or improper seal?

Are there any 'tricky' steps in installing an Aquia II that are different from a normal toilet install that could be missed??
Thanks.

Any toilet that leaks from the floor seal, you have to suspect a main line backup.

Thanks for the response Terry.
With a good seal, wouldn't even a main line back-up just overflow the bowl and not leak under the toilet onto the floor?

The leaking occurred after several flushes within a 30 minute period.
Could this be a slow draining main line?
Might I have two problems... the seal and main line back-up/slow drain?

These adapters are installed with a seal at the flange.
We normally use wax.
If you have a main line backup, don't expect wax to hold very much head pressure.
If it is a backup, the toilet flange is normally the lowest point in the home, followed by tubs and showers.
It's easy enough to pop the bowl off and check the flange seal though.

machabs9
08-20-2009, 07:43 AM
It turns out there were two problem at play here.

1) There was a partial main line blockage.

2) Also the wax seal used was not sufficient. I was told this model needs an extra tall wax seal. My contractors originally used a regular wax, for the fix they used a regular wax seal on top of a wax seal with neoprene(?) base. This double tall wax seal seem to do the trick, but only the next main line back-up will tell me sure. Does this sound right that an extra tall was seal is need for the Aquia II?

Happy Flushin'

Anytime the flange is lower then the finished floor, you need more wax.

Unless the flange is installed "over" the floor, it takes more then a single wax ring.

For any bowl or toilet.

But then any plumber knows that.
A handyman might not know that.

I have a bit of a side question, but I thought it would be good to keep questions regarding the Toto Aquia together.

Does the Aquia (not II or III versions) fit a 10" rough-in? It seems like it is the only version that uses the unifit adapter(?), but i just wanted to check that this was a viable option for my home.

Hello All,

Having read through Terry's great forums ~all night, I choose a CST464MF and ordered at e F a u c e t s. I then began finding negative comments about the small water surface and the advantages of the SanaGloss finish on some models of TOTO toilets.

I immediately (~10 minutes) notified e F a u c e t s to stop the order, but they did not. It's now about 10 hours later and e F a u c e t s states they immediately sent the order to shipping and can not modify the order (even though they responded to my email question that I wanted SanaGloss finish and this model did not have that finish). I attempted to change the order to the CST424SFG with SanaGloss finish but was told it is too late to change the order.

Bottom line, e F a u c e t s has a policy that even before shipping, despite a quick response to an email to cancel, will not cancel orders -- so be cautious!!

hello - just registered here - one of many stops after googling around looking for info on low flush units.

I found the timing is interesting (reading this thread) as I just stopped in at a local plumbing store where they have a skid of the AquiaII units selling for @ $390 (Canadian). Plus another $70 for the slow close seat (which I think is a great idea with my son's noise sensitivities, etc.) This is for new construction, with limited (cistern) water supply and septic - so we're definitely going to go with the most efficient low flush toilet we can find, provided it actually works.

Some of the other units I've looked at (e.g. American Standard FloWise) also seem to have a good MaP rating, and are about half the price at the local HD.

Seems from all the comments that this toilet has been around for a while, and has a pretty good track record - but I'm wondering if it's a bit overpriced? In what ways is it better than the lower priced big box units with a fair MaP rating?

In what ways is a Chevy Nova better then a Lexus?

The Chevy Nova has a 305 cubic inch V-8 engine.
It's not very stylish, and the bench seat hurts my back.
Drum brakes all around, so it doesn't really stop.
It looks like it was designed in 1968.

TOTO Aquia
Quality, less then 1% returns,
Softclose seat
Skirted bowl, easier to clean
Style

Now none of these things may matter to you, especially style.

But you will pay more for products with fewer defects.
Your home center toilet is for people that are shopping price, not quality.
A plumber will choose quality, because we value our time.

Your time isn't worth much.

At least, that's how the Big Box stores view you.

I won't buy lumber from a big box store either.

Thanks for the feedback. I like the analogy.

Yeah a Lexus is sure worth more than a Nova, but is it worth what they charge for Lexus, I guess is what I'm asking. People will pay more for a Lexus just because it's a Lexus, regardless of where and what the real additional value is. And they should expect to pay more, but how much more? Sometimes the higher quality item is way overpriced.

Put another way, I'm a cheap SOB :D - so your sanity check is much appreciated. Style isn't a huge deal for me, but I do value my time - and yours as well - so on that note, thank you for taking a few moments here to ease my mind about this particular product.

I did the install myself, I had replaced 1 toilet before this and it wasn't difficult for me. I am remodeling my second bathroom now, though started with the construction of a shower and will terminate with the installation of another Toto.

Great website -thanks, Terry!

Looking for feedback on a toilet choice. Although I do some DIY myself, I have pros doing a new master suite addition, so hopefully installer expertise will not be an issue, and there are no existing footprint/rough-in/tile issues to deal with.

Issues I'm concerned with (roughly in order of importance):
- Quality: nothing is worse than stuff breaking.
- Not clogging: BM's seem to be on the large size, and clogging has been an issue in the past.
- Water efficiency: the eco-nazi in me wants either a dual-flush or low-flush model, but I'm not tied to one over the other.
- Skid marks: seems like Sanagloss is a big plus for this, but unavailable on Aquia.
- Style: must be modern to match the rest of the bathroom.

I'm considering the Toto Aquia, Soiree, Ultramax, and the Caroma. I wasn't really looking at the Caroma until I read the user comments about the larger trap helping with large BM's. However, there were quite a few negatives about the Caroma that have me worried about it. Cost is not a big concern, but I don't want to buy a McLaren if what I need is an Acura.

I went to get the Toto - the box on the skid says "made in China". I don't want to start a debate on outsourcing here but - but curious - is this a recent development or have they been made off shore for a while now? reason I ask is that I have had some problems with other (e.g. electrical) components - older units that were once made in Canada / USA never an issue, then outsourced to China - high failure rate.

To be fair maybe they're really good at assembling toilets - just not sure if this is going to be a problem with quality down the road...? once bitten...

One thing that differentiates Toto from many companies is that they exert a lot of oversight and quality control over their manufacturers. Various bits match up, colors match, and you shouldn't have a problem. It's somewhat the luck of the draw where it actually comes from. Some are made in Georgia, and varous other places around the world.

A second thing is that they use a low moisture casting process that means there's much less variation in casting.

My question is this.....the toilet has been working great, it is not leaking. The tank has a little bit of a wobble to it, I am afraid of overtightening the tank screws. Is a little wobble okay....or should i keep tightening? The bowl does not wobble thanks to some composite shims.

when Honda was starting to manufactuer cars in North America and everyone thought the quality would go down Quality did go down. Fit and finish and other non cosmetic problems were worse in my newer N.A. built Honda than an old Honda. The new one had the usual routine transmission failure far far below 100,000 miles. Along with many other issues present from the beginning. Dealer claimed no problems existed. Friends driving the car found the problems without any hints. But it took a year of repeat visits to get most of them fixed. Dealer tries to shine on and blame the owner for the transmission but it is a common problem on some years V6 models. Even Consumer Reports found this out. The car was assembled in North America. The transmission was made in JAPAN. Yes, I did far more transmission maintenance than the Severe schedule and have not towed. I would not compare Toto with Honda unless you were trying to insult Toto.

Never heard of one on a their cars failing below 100,000 miles actually... Mine had no trouble in the 150,000 mile range and the motor and transmission acted like they would run forever. Was yours a minivan (Odyssey)? All of the minivan makers seem to have serious problems with short transmission life--about the same lifetime as an F150's (70-80K). :eek:

Domestic makers had a lot of trouble with transmissions lasting only 20K or so. I remember having a discussion with a coworker where he insisted that there was no difference. I then asked him how many transmissions his suburban had...it was on #3 at 80K.

Based on what I've seen I would rank my Nissan as the most reliable, my Honda #2, Toyota #3, and then dragging in miles behind would be Chevy/Chrysler/Ford. Good luck picking out which one of those three was worst...but they did have AMC beat.

Done by professionals. Two questions. First, the screw caps for the slow closing seat aren't attached to the seat. They seem to be attached originally but broken. Can someone let me know if the caps are attached? Second, seems I need to hold the big flush button for a second or two, otherwise the flush is pretty weak, actually weaker than the small flush. For a while, I thought something is wrong. Then I pushed and held and it seemed to work. Can someone confirm that the big flush requires holding down the button for a bit? Thanks.

http://www.terrylove.com/wc/toto/ss114_02.jpg

The caps on the seat come attached, but if you haven't pressed the caps down, and then work the seat up and down, it can snap them off.
They should be pressed down before the seat is opened or closed.
Once the tab is broken, you can still press them down, but it doesn't look as nice.

You may need longer pushrods on the button.
If you call Toto tech support, they can mail you longer pushrods, sometimes a rod 1/4" longer is all that is needed.
In the interim, you can place a coin under the button to space it out a bit.

How does this compare to the Drake? Does the dualmax flushing clean the bowl well when it comes to solid waste? Is the same flushing technology as the Drake?

I can't compare results to the Drake but I bought two of the Aquia IIIs a couple of months ago. No issues at all so far. The issue of "streaking" is rare, about the same as with my old dinosaur 3.5GPF. It usually washes down by itself during the refill process. Once or twice I've just hit the #1 button to clear things up. (I just knew I shouldn't have had those bean burrittos!).

Have used the Aquia II for a week now. Flushing seems to be strong after using a coin per Terry's advice. Got the longer stick from Toto today which worked as well.

However, because of the low water mark, there's quite a bit of residuals from solid waste every time. A little annoying to say the least.



Some people drop a square or two of paper down first.
That, and the bowl gets better after a couple of weeks.
New bowls seem sticky, but that being said, it's styled more like toilets in other parts of the world, with less water in the bowl.
The Drake bowl with Sanagloss will stay cleaner.

Thanks again, Terry. I also suggested to my kids to throw in a toilet paper before the big one. Hope it works.

Had the Acquia III installed about eight months ago. Excellent performance, even with the challenge of a bout with an intestinal organism. We saved a lot of water over those few days, thanks to the AIII.

My question is about cleaning products for the toilet. The Toto materials say not to use any products with chlorine, but I haven't been able to find any toilet cleaners without chlorine. Can anyone sugggest a product?

Love the softclose seat--it's a bit of a problem when I use a toilet without the feature, because I have gotten in the habit of flipping the seat closed and walking away. Works fine for softclose, but for normal close--noisy! Oops.

I'm not sure that the dual flush is functioning correctly--it seems to sound the same whether I use the small or the large flush. I'll do more research and ask questions on that later.

Great forum. Thank you so much.

if you want a do it yourself, i use Vinegar and baking soda.
Not only does it clean; according to Heinz company information, the same vinegar that you can buy at the store as a condiment actually kills 99 percent of bacteria, 82 percent of mold, and 80 percent of viruses.

Just purchased this toilet two weeks ago. Looks great, flushes pretty good although noticed the need for brushing the inside of the bowl on occasion. My only complaint is with the half flush. It doesn't seem to actually fully flush as the water level never goes low enough to clear. If I do a full flush, I definitely see a proper flush taking place with water going low enough to fully clear the drain.

Any suggestions on how to change this? Do I need to change the amount of water that drains from a half flush?

You may need longer pushrods on the button.
If you call Toto tech support, they can mail you longer pushrods, sometimes a rod 1/4" longer is all that is needed.
In the interim, you can place a coin under the button to space it out a bit.

Thank you so much for this simple and perfect solution! My new Toto Aquia was installed last night and used for the first time this morning. I studied this forum before purchasing it, relying on the advice from Terry and the other folks who post here over the opinion of the salesperson at a local high-end plumbing store, who told me that I wouldn't be happy with the toilet (and then tried to sell me a cheaper model from a different company - maybe she's on their payroll, I'm not sure). Imagine my dismay when I flushed the toilet this morning and found that even the paper didn't go down! My spouse was furious with me - four days before Christmas, one day before company arrives, and I've installed an expensive toilet that doesn't do what it needs to do - and insisted that I call the plumber right away. I figured I'd check back here before I called for help, see if I had missed anything, and look here, the very advice I needed. I set a penny under each pushrod and the toilet now works perfectly. I'll call Toto about the longer pushrods today, but in the meantime, if a plumbing forum could produce a merry Christmas, this one has!

Thanks for all the good advice in these forums; they're incredibly useful.

Terry, if Toto listens to you (and they certainly should) and/or you have a good contact, perhaps you should suggest they add an optional set of longer push rods to the tank hardware baggie. They could also update instructions/troubleshooting guide to explain what to do if this issue appears.

All toilets have a water supply.

Kurts was on the far right.

A water supply should have been on the left.
It was a trick hooking that one up. We had to use two supply lines, one was a Delta end, that allows a standard 3/8" end to thread onto the male threaded end from the Delta style supply. ( I'm putting that information down for the plumbers that could use that trick) We keep a few on the truck, just in case we find bizarre out there on the job. It saves an hour or two sometimes.

I'm surprised by the photo of the short push rods. I bought 2 of the Aquia III's and both came with much longer rods.

Is there a QC problem at Toto or did they start running low on stock and start cutting them in half?

I installed an Aquia ADA and an eco-drake ADA a year ago this week. I originally purchased two Aquia, but had to trade one due to space limitations.
After initial installation, just for grins I used the small button after a big job, and it flushed perfectly, and removed everything. Since that time, over a year, the large flush button has never been used on this toilet, and can only remember having to use the brush, perhaps twice, at most.
I like both toilets, but the Aquia is a winner for sure. I installed it out of the box, with no adjustments required, and no problems ever encountered.
I'm sold and would never buy any other brand....

Hi Terry,

Who knew I could spend so much time and take so much pleasure out of reading about toilets? :-) I have been lurking your site for a few years now and taking your advice.

I installed 2 Toto Ultimates in the main bathroom (2006) and ensuite (2007) (I think that they are 1.6 gpf models) and loved them.

I then installed an Aquia III dual flush in my powder room (2009) and have had little success with it. I tried putting quarters on the flushers and they just fell into the tank after a couple of flushes. Toto sent me longer straws, and the only result was the flushing buttons stick up very high and look odd. The only way I can make the 0.8 liquid flush take even one small piece of toilet paper is to hold it down for a 3-count, which I think is overriding the low flush. The solid side, I also have to hold down for a 3-count. I am also not impressed when I have to clean the bowl after every solids "event" - it seems that I am the only one in the family who notices...

We are building a new home and I want to install 3 x Ultimate 1.6 gpf. But seems that now only 1.28 gpf models are now available. Do they work as well as the 1.6? This forum doesn't seem to distinguish between the two. I am not concerned about the increased water use of a 1.6 because we are also installing a BRAC system that recycles the shower and bath water for toilet flushing.

Thanks!

I have 2 of the Aquia III's and have no flush issues at all. You may have a setting issue with the flush tower.

I still have the original install instructions scanned and cut/pasted a portion showing how to check/adjust the Flush Valve tower for the partial flush.

You can also find a video to two with the flush demo's for both the .9 and 1.6flushes to compare to how your toilet is performing.

Hope this helps. Otherwise the many experts on this site should be able to point you in the right direction.

P.S. I know you don't seem that concerned about water usage but my first full quarter water bill just arrived since the Toto's were installed. Overall, usage is down 30% in the quarter compared to the same period last year with old 3.5GPF Mansfields.

Thanks Firemark. I have adjusted it (might have been a little low) and will try this for a while.
I am very concerned about water conservation and the environmental impacts of wasting this resource. The reason I am not concerned about water use in my new house is that we are going to install a Brac system which will filter and collect the water from showers and use for flushing toilets. So I hope I won't be paying for any new water used only to flush.

I installed a Toto Aquia a couple years ago. It never clogs, even using the .9 gal flush, but I usually have to brush the bowl after each non-liquid-only use and then flush again. Also, because of the shape of the bowl, it is difficult to clean with a standard brush. Does anyone have any brush reccomendations?

No, the toilet will just sit that 2" extra away from the wall, so yes, you can use it. The Aquia is now available in both 12" (original) and 10" rough-in versions, but I've not seen a 14" version.

I read in one of the threads that something on the Toto is "open" at the back, so I wanted to see if there was anything specific to the Aquia II that would make it a bad idea to put the 12" toilet on the 14" rough in. I am looking forward to having that skirted design, and the dual flush. I first saw those when I visited Sydney in 2002 and I was impressed. :)

Yes, the toilet will flush in this manner. Another approach is to use the bucket to fill the tank, then fill the bowl (you have to do this slowly, or it will flush again).

I can't remember if I gave a review of my Toto Aquia II -- anyways, we've had it installed for about 5 months now and it is excellent. It looks great, never clogs, and is very high quality. Adds a lot of sophistication to a bathroom. The softclose seat is, in a word, delightful.

Compared to a standard toilet, it is far more complicated to install, but as a project in itself it is quite straightforward for the average weekend warrior. If you follow the directions and have a decent set of tools, you will be done in about 2 hours at most.

You will not regret buying this toilet!

We have just had installed three Aquia dual flush toilets as part of a whole house remodel. We love the toilets and have the Terry Love website to thank for helping us select them. However, we have one problem, all three wobble when you get up from sitting. Our contractor claims this is how this toilet is, I can't believe it's true! I called Toto and they say they haven't had this issue and recommended shims. My contractor doesn't want to deal with it and I'm not excited about shims on the floor as it would seem a cleaning issue over time. I'm just wondering if there is anyone with experience with this and what their solution was and how I could go about fixing it. (It's disconcerting to have the whole toilet move everytime you get up.)

Thank you!

We always give our customers shims with our install kits.
You can't guarantee that the floor will be flat.
A bowl should be shimmed if needed, and then caulked to the floor using something like polyseamseal.
We like to use the clear that can be cleaned up with water.

If the bowl has movement, you slip a shim under the bowl near the back, pinning the front of the bowl down.
Score and snap the shim, and then caulk.

We pick up our shims in the door department, made from plastic about six inches long with a nice gradual taper to them.
When we or our customers install toilets, there is no movement in the bowl when done.
I'm sure you will be able to do a better job in 30 seconds then your "handyman" could.

Also note that you probably should reset the toilet with new wax. The wax isn't a spring, and once compressed, then rocked back the other direction, it will leave a gap. IF the line ever clogs up, it will leak waste out that gap, and sewer gas could always come out. It is likely small, but it is there.

Fo some reason our plumber installed the rough-in at 15 inches from the wall behind it (probably because code for space on each side is 15).

Toilets are designed to 'stand-alone'. So they could be in the middle of the floor and it would have no effect on how well they work (assuming the waste lines are installed to spec). They aren't designed, or need, to have any other support than to sit flat on the floor.

Terry
08-17-2010, 01:54 PM
Your "plumber" roughing in at 15" may have to do with floor joists.
There is no code that says a the toilet is 15" to the back wall, most stanard rough-in's are 12"

Code calls for 15" from center line to the side, not the back.

Toto does make the Vespin, which can be installed with a 14" Unifit, that would pull the bowl back 2"

First,

Like a lot of folks, I NEVER thought I would spend so much time researching a toilet. However, your site has some of the best information I could find anywhere! NICE WORK!

I've done a lot of research and like a lot of folks transitioning from what I know to what is better is a bit of an adjustment. The feedback from all the users has been an immense help. So...

My limitation is that my home has 2 bathrooms with 10" rough-in. I have found that it seems to have reduced my options quite a bit, especially in dual flush. I've read enough to rule out the Caroma. So, I think after all my research that the Aquia CST412MF.10 is my best choice.

The installation instructions are made for a couple model variations and think I understand the difference but just to make sure...Does the model that I am planning on buying still mount conventionally straight down onto the socket? With the exception of adding the mounting blocks, it seems rather straight forward.

Also, my water outlet is about 5" above floor (6" recommended) and 6 3/4 to the side of the center of the outlet (7 3/4" recommended). Do you see that as being a major issue?

Hey, I work for the government...measure it with a micrometer, mark it with a grease pencil, cut it with a chain saw. :D

Is there another model you think I should look closer at?

TANX!!!

Hi Terry,
I'm currently planning a new house and we're trying to choose the best toilets for our needs. I've really appreciated your forum and website. I have two questions:

1. Our current, very old gravity toilet often clogs with large solids. Based on what I've seen, it would seem that a larger valve opening would be good for this (3" vs 2"). However, we would also like dual-flush, but the Toto Aquia has the smaller diameter opening. Any suggestions?

2. I'm a Consumer Reports junkie. Their 2009 ratings seem to show the Kohler and American Standard ahead of Toto by quite a margin, although they don't review the Aquia. Any thoughts on this?

Thank you so much.

Terry
10-24-2010, 12:09 PM
Consumer Reports?
The guys that flip the handle a few times and then give their "expert" recommendation?

CR's top choice for a dual flush (http://www.terrylove.com/forums/showthread.php?30226-Consumer-Reports-Recommended-toilet-Gerber-DF-21-318-a-big-Flop!)
I was in Detroit with Flushmate this Fall, and they were laughing at how bad the Gerber dual flush was too. The dual flush unit in the Gerber is made in China. And yet CR gives this piece of junk their best buy.

CR gives the Kohler Cimarron (http://www.terrylove.com/forums/showthread.php?4834-Kohler-Cimarron-toilet-review-Owner-comments-and-pictures)five listings on their report, why? It's just one model.
The rinse isn't that good, and it plugs more then others. The handle is hard to push down for older people. Quality control could be better.

CR also like the Cadet 3 (http://www.terrylove.com/forums/showthread.php?11570-American-Standard-Cadet-Three-Toilet-consumer-product-review)
Quality control is an issue here too. I guess CR doesn't care about those things though.
For someone looking to spend less, it's an option though.

CR list the Flushmate Gerber (http://www.terrylove.com/forums/showthread.php?28088-Gerber-Ultraflush-pressure-assist-toilet-review-and-comments)about four times, again same toilet, four listings. Why?

CR does show a video of the toilet I have in my main bath, the Ultramax II (http://www.terrylove.com/forums/showthread.php?22139-TOTO-Ultramax-II-Gwyneth-MS604114CEFG-toilet-review&highlight=ms604), but they plug the outlet of the bowl and then take the video. It's the dumbest thing I've ever seen. Why is CR cheating on their testing?
Are they taking paybacks?
I have the same model in my main bathroom, and mine works great, in fact for someone with an ileostomy bag, it's my first choice. That and the Drake II. The Sanagloss coating in the bowl is a big plus.

http://www.youtube.com/watch?v=Xn9_zctMge0

I've sold about 300 of the TOTO Aquia. It's been trouble free. Not something that CR would care about.
They don't have to live with the product after they flip the lever, or service the product for customers. Plumbers do have to deal with the product years after installation.
They don't have an ileostomy bag to deal with either, but others do. One person in twenty will develop colon cancer in their lifetime.
That in itself changes the whole ball game. Any of the TOTO products with Sanagloss will be a big difference maker for that.

The Aquia has a good flush, but the Aquia II and the III have the 2-1/8" trapway like the others. For 99.5% of the population, that works fine. There is a tiny percentage of people with a medical condition that requires a larger trapway for large hard stools. For those people, I like the Caroma dual flush with the 3" trapway.
For the average (majority of the population) user, a trapway of 2-1/8" works very well.

The TOTO Drake (http://www.terrylove.com/forums/showthread.php?5241-Toto-Drake-toilet-product-review)has been working very well for customers too.
I've been selling those for $239.99 (http://terrylove.biz/home/84-toto-drake-toilet.html)in the Seattle area.

Hi Terry,
1. Our current, very old gravity toilet often clogs with large solids.

I installed two Aquia III's over a year ago after ditching old Mansfield 3.5GPFs that clogged up at least once per week. Your reference to "Large" was my concern at the time as well. However, I was concerned about volume not bunker buster size. I also looked at the Caroma but a nasty video posted online with lots of splashback made the Aquia my choice.

I'm happy to say the plunger has been retired to the garage for storage and never used since the Toto's were installed.

Terry mentions Sanagloss as a good option to help keep the bowl clean but the Aqiua's don't come in Sanagloss unless that's a recent change.



No Sanagloss on the Aquia

Can someone summarize for me the feature differences and/or advantages of the various Aquia toilet models CST 412MF , CST 464MF, CST 416M-01 and CST 414M-51. I really appreciate any help. This is a very good forum. Thanks and best regards.

CST414M is a 15-1/8" high bowl using the more complicated floor mounting, with an open back bowl.

CST416M is a 15-1/8" high bowl with the less complicated floor mounting, the back of the bowl is closed.

CST464MF is a 16-1/8" high bowl, otherwise like the CST416M

CST421MF is a 16-1/8" high bowl, otherwise like the CST416M

M = dual Max flushing
F = 16-1/8" high bowl

Hi,

I never thought I would spend so much time researching toilets. I am stuck between Toto's Aquia and Kholer's Strela. I am not sure which toilet is better. Could you please advise? Also, what is the difference between the Toto's CST412MF and CST464MF? These toilets are the same price.

Thanks for your help in advance.

I've installed my new Aquai ... almost... I'm about 1/2" from the bowl being pushed back to where it's supposed to set. On one side I can screw in the mounting bolt, but not the other - so I'm thinking it's off a bit, but nonetheless I cannot push the bowl back any further. I measured everything and even soaped the ring as you suggested... The only thing I can think of is that the bowl is rubbing against the mounting blocks making it impossible to push it back any further. So, what do you suggest? Can I somehow trim the mounting block - rather than taking the whole thing back out and moving the blocks? That's the easiest option to me that I've thought of so far - but want to get advice from you before I try anything.

Thank you -
Michael

The blocks are there to receive the attaching screws. I little triming shouldn't hurt.

You must have the CST414M Aquia if you are sliding the bowl toward the wall into the adapter. How far from the wall was the rough-in?

Yes, it's the cst414m and a 12" rough-in.

I installed the Aquia II a few months ago thanks to this site! I am now noticing something unusual - after a flush the bowl empties and refills. Within a few hours though the bowl is back to almost empty like it is draining somewhere. There are no apparent leaks and it seems to flush with the same force as always. Any ideas as to where the water is going and how to stop it?

Thanks!

There should be very little water in the bowl when at rest.
Are you sure there isn't a plug somewhere, and that the bowl is being overfilled and then seeps down to it's natural level?

I installed a Toto Aquia III this past Friday. It took me longer to read and understand the instructions than to actually do it. I installed a new brass nipple and 1/4 turn valve as well and the whole process just took a few hours. The extra flange and mounting hardware is a great idea so if the toilet has to be removed, the wax seal still remains intact... unlike a traditional toilet installation.

And my girlfriend loves the soft close seat. She won't miss the toilet seat banging in the middle of the night. Ha.

I'm considering replacing my upstairs toilet as well... but it might be a 10" rough in. I'll have to check.

This place is a great resource! Thanks again.

Thanks! The water level seems to be filling up to the level in your picture and then occasionally seeps down so it is just below the opening to the drain (does that make sense?). It doesn't happen with every flush and otherwise the toilet is functioning well.

Do you ever flush dental floss or hair down the toilet? On occasion, those strands can act like wicks and let water out. Also, if the toilet is not used for extended time, and the house is dry and or hot, you'll get some evaporation. But, if it drops to that low level regularly, and within hours, there may be something wrong.

It could be as simple as the overflow hose is misplaced.

I've experienced the same thing on one of two Aquia III's on rare occasions in the past year. My best guess is it's caused by my washer discharge that is within 5 ft. There's so little water in the bowl normally just a bit of suction will pull some out. Both the toilet and washer share the same vent stack. I haven't checked the vent stack for blockage.

Terry
11-08-2010, 03:49 PM
Or if you have back to back toilets, sometimes flushing the other toilet will cause some water to leave the bowl.

Hello all, I would like to put in a toto aquia ii. I've read the rough in should be 12 inches. I just measured 11inches from the back wall to the center of the hole. Does this mean it won't fit? Thanks for your help.

Make sure you are measuring to the finished WALL, not the baseboard or trim, unless the trim is quite tall. The spec sheet showing dimensions is on the www.totousa.com (http://www.totousa.com) website.

Terry
11-13-2010, 09:30 AM
95% of all homes have a standard 12" rough-in. That's the distance between the back wall and the center of the drain.
That normally is the center of first set of bolts that hold the bowl down.
The Aquia needs 11-1/2" or more.
Yeah, I'm 95% sure.

I'm in the process of finishing a new bathroom, i am just about to tile the bath floor and am interested in a Aquia III. I have seen the Install pdf from Toto's website but want to make sure im not missing something. I have never installed a toilet so this is all new to me, what im wondering is do i need to install anything prior to my tile going down around the toilet drain? or is everything installed after the tile is laid down?

thank you,
Brian.

Terry
11-18-2010, 11:00 PM
The toilet is the last thing installed. The floor comes first, then the toilet sets down on the new floor.
The back mounting blocks will require drilling four holes through the tile. This is because it's a skirted bowl and the mounting is a little different.

mcdonaldb
11-19-2010, 06:28 AM
Terry, i should install the closet flange over the tile also, correct? and this can be a regular closet flange from a big box store, i don't need anything specific for the Toto toilets.

Terry
11-19-2010, 09:15 AM
A closet flange works better if it's installed over the flooring.
Often you don't see that though. If a standard closet flange in installed over or on top of the flooring, then one wax ring works.
If the closet flange is on the subfloor and then the overlay and tile is cut around the flange, then a second wax ring would be needed.

Yes, a standard closet flange.

jadnashua
11-19-2010, 10:55 AM
There are lots of models of toilet flange. The preferred one has a SS metal ring rather than the painted steel one. Now, you shouldn't get any leaks there, but the SS one will be fine 50-years from now, but the steel one might be dust. This assumes you have plastic pipe (pvc or abs).

mcdonaldb
11-19-2010, 03:03 PM
yes ABS pipe.

Here's the deal. I want to install a Toto Aquia. Toto says I can't do it because the water supply MUST be per their 8-10 inch recommendation.
My current measurements are: 6 inches from water supply valve to the center of closet flange;
5 inches (height) from floor to water supply (this may lessen with new pebble tile install);
12 inches from finished wall to center of flange (this is an estimation - won't know exact measurements until I take out existing toilet.)

From what I can see from this blog, I CAN install despite the TOTO recommendations.

But since I am clueless when it comes to things like this, I don't understand how this is possible. I can't find the actual dimension of the back skirt area of the Aquia or Nexus. Is this important?

Is there anyway I can install an Aquia or Nexus without having to move the water supply?
If so, HOW and which models will work and do I need to buy some special adapter on the water supply. Or should I just plan on moving water supply?
Thanks so much for your help.

Terry
11-30-2010, 09:34 AM
You have plenty of room.
They say eight inches for every toilet as a safe recommendation.
With the Aquia, you can have it behind the bowl.

Terry, I am new on here. I was planning to do the Consumer Report recommendation for Gerbers Dual Flush until I saw your experience. Thanks for heads up.
I have studied your recommendations. Am considering using Aquia; want best performance and conserve water, have elongated bowl and ADA height. What is better the 412 or the 464? (The 414 you recommend is lower height; MaP seems better on the 412 than 464 from what I found.)
Also considering Drake II (454) for different bathroom - is that as good as regular Drake (744) you recommend? My plumber is able to get better price on Drake II right now. Thanks in advance. mj

jadnashua
12-11-2010, 04:02 PM
The style of the toilets are different between the Drake and the Aquia...the Drake II is newer than the original Drake, and if that style was to my liking, I'd go with it verses the original Drake. From what I hear, it has better bowl wash and is easier to keep clean. Less expensive is also a bonus!

Terry
12-11-2010, 05:02 PM
The Drake II is good.
On the Aquia, we sell the CST416, CST464, and CST412
Those are all pretty equal. The CST414 would be a factory order.
I don't think you have to worry. I've been selling all of these for years with very good results.

A client asked me to install a Toto Aquia II toilet in his master bath. He has a concrete slab subfloor, and I didn't bring the proper tools to drill the holes for the mounting blocks. The whole mounting system that Toto uses is completely foreign to me. I seemed to miss the holes in the bottom of the skirt where screws connect the toilet to the mounting blocks? Is this the way these toilets mount? I was somehow under the impression that the toilet "snapped" down over the mounting blocks. This would seem to make "uninstalling" these toilets next to impossible. Obviously (I hope!) I'm missing something here. I was recommending the Kohler Cimarron, but my client is short and doesn't WANT a "comfort height" toilet. Comments would be appreciated.

This installation guide (http://admin.totousa.com/Product%20Downloads/0GU031,%20DUAL%20FLUSH%20TOILET,%20IM,%20V.03.pdf) should help answer all your questions.

Yes you are going to need to drill and fasten it to the floor.
It's not as hard as it looks, try Tapcon screws with the concrete floor.

Am I eventually going to love my Aquia the way other people seem to? I hate it! There doesn't seem to be enough water in the bowl to do anything. I have to wash the toilet bowl daily, unless I want guests to think I haven't washed it in decades. Today, I dropped a poop from my daughter's diaper into the toilet and flushed it within 10 seconds, yet the bowl remained dirty. What gives??? Hellllllpppppppp. :(

We just bought a CST412MF but it hasn't been installed yet. I've ready good and bad about the dual flush models with regard to staining, as well as the amount of water they hold and how well they take away the waste. We have a single flush Toto in a half bath and love it. We wanted the dual flush for some versatility in the master bath and that's why we got it. Have we made a mistake? Will this stain regularly and/or not take the waste away on one flush? What about this trickling sound I read about? Lastly, does anyone know if the model we got is ADA? It says it's "universal" height, and I'm not sure if that means it is or isn't ADA height. Thanks!

Terry
08-02-2011, 01:56 PM
Universal Height is ADA when the seat is added.

I've sold maybe 300 of the Aquia toilets, many being repeat purchases.
There is more bowl surface then on the Drake, but the water does rinse the bowl down.
Any new bowl since 1992 uses less water and has more bowl surface. Most of the time, everthing will be fine. And if not, that's that a toilet brush is for. Some people report that everything will flush with the half flush, 0.90 gallons.
Some of this depends on diet. If you love Hersey's chocolate, then you might need the brush sometimes.

While the bowl is refilling, you can hear water in the trapway until the bowl is completly filled. Not a big deal, and after you've had it a while you forget it's there.
If you have a refridgerator in the home, you will hear the motor humming, the icemaker filling trays, the channel changer on the tv clicking sometimes, the sliding door making a rustling sound everytime someone opens the door, so, so many sounds in a home. Even the creaking of the wood as the home cools during the night, and then creaking again when the sun comes up.
If you can't deal with hearing some water, then a solid porcelain trapway may be better.
For most, it's not an issue. Clocks make a tick, tick sound too. Noise, noise everywhere.

jadnashua
08-02-2011, 01:57 PM
Most toilets are entirely porcelain in the bowl and trap. Some Toto models use a plastic adapter (those that use the Unifit, and a different version for the Aquia, and some others). The plastic doesn't insulate sounds as well as porcelain. 99% of the sound happens in the first few seconds of a flush, and is kind of irrelevant. Because the bowl is typically filled to the brim, any time you add something to it, a little water trickles out down the drain. This is the sound people are talking about. After the first week, you don't notice it, like the sound of a new clock.

ADA requirements dictate more than one feature (seat height is only one of them), so that toilet may not be ADA, but comfort height generally qualifies for that particular part of it.

A dual-flush toilet must be able to totally empty the bowl on the smaller flush. As a result, the water spot in them is typically smaller than a single mode toilet. If you push the right button, it will flush what's there. But, if you don't hit the water spot, you're more likely to have some skid marks that may not wash off in the first flush. How serious, if a problem at all, depends somewhat on your diet and how you sit on the seat.

Thank you all for the helpful info. I feel better about our purchase. I had also read that there are gaskets around the base of the tank and perhaps one other place I do not recall that tend to leak over time in the dual flush toto, or even at the beginning if it's not torqued really very tight. Anyone heard of this? Otherwise, I'm looking forward to many years of faithful and carefree service. Thanks again.

You simply tighten the bolts evenly. It's that simple.

Here is the one-piece version of the Aquia.
Now you pull the bowl from the box and stick it down on the flange adapter and over the mounting blocks.
No need to even install the tank, it's all molded in.

Just thought I would throw my two cents in here. I installed this toilet and had a leak on the left tank bolt. I tried removing the tank and re-installing several times. I tried sanding the inside of the toilet around the hole and re-installing. I went so far as to alternate tightening the tank bolts a quarter turn each until they were tight. I tried over-tightening to the point where I was worried the tank would crack (thank goodness it didn't). Each time, it leaked. Finally, I used a coat of RTV silicone on the rubber washer that seals inside the tank. This fixed the leak. I'm not sure what else I could have done, but now the toilet is working great.

I noticed the Aquia one piece only has a 1-3/4 inch trap compared to the 2-1/8 trap on the Aquia CST416M. Do you think that this could affect the performance in a negative way. Does anyone have any real world experience with the one piece Aquia?

we have 11", not 12" for the rough in.

You can set these at 11.5"
You may be able to fudge the adapter the rest of the 1/2" by setting it offcenter to the flange.
The outlet is 2", and you are dropping it into a 3" pipe. There is some room to play with there.

We sometimes use a flange repair ring to hold the closet bolts at the "new" center.
Do not use an offset flange.

Hi!
I need some help with a powder room project and would greatly appreciate if someone with an installed Aquia II 12" rough-in toilet can provide me with some measurements. The issue is that my chrome threaded pipe nipple is 3" from the center line, protrudes 4" (including the valve) from the wall and is 5" off the floor. I was planning to install the Aquia II (CST412MF or CST416M) toilet and need to know if the back of the toilet can accommodate my current nipple placement. It would be very helpful if you can let me know the rear clearances.

If the toiler rear cannot accommodate the nipple, can someone let me know how easy/difficult it is to swap out the nipple with a new shorter one? I am only experienced with copper pipes.

Thank you!!

If it doesn't fit because of the protrusion, you can install one of these Dahl Skirted Toilet kits, which is basically an integrated 90 with a quarter-turn ball valve attached.
