We just moved in to a 2 year old house. There are mansfield no.160 1.6gpf toilets in the house. 2 upstairs and 1 on the first floor. The upstairs toilets work just fine but the downstairs toilet frequently does not clear if there is solids in the toilet. We have found that holding down the flusher until the solids are cleared solves the issue.

Any ideas on what the issue is? If there is nothing in the toilet it flushes fine every time and seems to have decent suction. as soon as you throw some toilet paper or waste it seems to give up late in the flush.
 
If they are Mansfield 160 toilets, you are lucky any of them flush consistently. The are a builder grade toilet installed for very little money.
Performance was never the reason they were installed.
We remove many of them.

You can always try an auger through the trapway to make sure there is nothing there.

Builders put these in so I can make money replacing them.

I just worked on two of these today

And the deceased (guy died last january) took the flush towers out of the old style 3.5 gallon flush mansfield and a 160 model, a 1.6 gallon flush with fluidmaster retrofit flush valves with flappers.

Both toilets are heavily overflushing, using way more water than required.

Mansfields have a heavy dominance in my area but some people have nothing but chronic problems with them.
 
Builder put these 1.6 gal Mansfields in my house as well - back in 1995. A lot of the neighbors replaced them right away. I was too cheap, and eventually replaced the flush towers and old-style ballcocks with the fluidmaster fill valve and flapper/flush valve as well. They worked better, but still plugged all the time. Not sure there is anything you can do to improve the flush performance on these if they haven't improved them over the years.

Additional comments on the Mansfield. If they still have the white flush tower, it gets difficult to lift the handle when the seal begins to wear out. Somehow, it generates a lot of suction. Also, if they still have the plastick ball cock with the float - the hinge on the ballcock broke and flooded a neighbor's house.

thanks for the responces. that is what I suspected. Any recommendations for a better quality toilet of the same size? This toilet is a main floor toilet and gets a LOT of use.
 
The workhorse that gets recommended a lot is the Toto Drake. I put two into my mother's house...don't want to hear about problems, so chose these upon the recommendation. They work great. I have a couple of different models (different style) in my home...they wouldn't have fit into hers in style, but they also function well. You have choices, ADA height or not, elongated or not (very male friendly), special glaze or standard, 1.6g or 1.28g, and color.

Toto is the largest bathroom fixture manufacturer in the world and has manufacturering in the US as well as many other places around the world. They make good stuff...
 
last question. is the distance between the floor bolts universal? i don't want to mess with putting in new floor bolts so I want to make sure whatever toilet I get has the same bolt pattern as the mansfield no.160. currently looking at those HE toto toilets.

This in in particular seems pretty nice. I like the features.

And if those appear to be too far away, call your local plumbing supply houses and ask for quotes on the specific models you want (get the tank and bowl numbers and cross check.) I found that my local supply houses gave very good prices on these. The negative is that you can't see and touch a display model ahead of time.

You shouldn't have to pay any freight through the supply houses is you are willing to wait for them to get their normal deliveries (could be weekly, monthly, etc.)
 
In the USA, the flange bolt pattern is standard...any toilet designed for USA use is designed to fit on a standard flange. You should not have to change the bolts, but they generally just slide into the flange, and should be readily able to be replaced if they are rusted, or messed up. Their actual length may be an issue...if they were cut short for the new toilet, you might need to replace them. If long, it's easy to cut them off some. There is no standard on how long they need to be, only their position. Most come long, and you cut them to length.

thanks again everyone for the help. this thread has been invaluable to a young new home owner who has never done anything more than flush a toilet plumbing related :)

Going to try my hand at installing a new toilet now.
