 Toilet Trap Diameter
Author: jkeefeholmes

I am doing a garage conversion to an apt for a relative and need to assure the toilet is the least likely to clog as I can. Is the trap diameter the key thing in this aspect? This person has a bit more than average clogs due to diet I suspect. Maybe 1 every 4 or 5 weeks.

In addition this person is handicapped and needs a higher elevated one, bigger size etc, though I guess my contractor can do something to elevate it if neccesary.

I have seen some that have a small square flap or door near the bottom on the side. Is this to assist in unclocgging? I don't understand what thats for.How could you get at a closed pipe. Not sure what that littel trap door is for. Totos brand

What are the best non cloggers, is the trap diameter the key thing too look for? most so far seem to be within 1/16" of each other so I have to wonder if thats very important or not. Any advice would be apprecaited. I am told 'commercial' types have large traps and that would help. ?? Thanks.

The size of the toilet's waterway is a factor, but whether the toilet uses the flush water efficiently is just as important. That "door" is to allow it to be connected to the pipe, not to unplug it.

in addition, some toilets have a glazed trapway. this helps things slide along easier.

Thanks for the replies so far. I found this re a $93 toilet (tank not included) AMerican Standard Champion

Industry's largest siphon outlet (2-3/8"), fully glazed with no choke points, virtually eliminates clogging
High flow 3" flush valve design allows maximum, water flow using only 1.6 gpf

What is the siphon outlet, this one seems to be a lot bigger than avergage, at least accdg to their diagam. Is this siphone outlet signifciant in anti clogging?

I just installed a Cadet3 from the Depot, with a 400A and brass bolts.

Sounds like the boat came in with the right parts... What was wrong with it?
