    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.

    Thumbs up Aquia


    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?

    Default Now in stock

    I now have the Toto Aquia in the Seattle area.
    We installed our first one on Thursday November 3rd.
    It's a very nice looking dual flush toilet with an enlongated bowl.

    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.

    Default Pictures please?!?

    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/onlineca...l&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

    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!).

    Default residuals from solid waste

    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.

    Default Toto Aquia DF Installation Complete

    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!

    Pennies, dimes, or nickels...cheaper and more readily available than running out to buy shims...

    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.
