I'm going to be installing a rear outlet toilet in my basement shortly. It'll discharge horizontally after a 90 degree bend into the sewer outlet in the foundation wall. The distance from the 90 degree bend to the wall is about 20" and the pipe has the proper slope. The pipe is 4" PVC by the outlet and goes to a 3" PVC "T" at the toilet flange.
I bought a Kohler Barrington a 2 weeks ago but I'm now contemplating returning it and buying a Caroma Sydney rear outlet. The main reason is that its a little shorter and the more important reason is that I haven't read much on the quality of the Kohler whereas the Caroma seems to get to reviews here.
What do you all think?
