My contractor left me with a 3" WC PVC rough in. The PVC pipe comes straight out of the cement slab and no space was left for an over the pipe closet flange.
While inside the pipe 3" closet flanges are available people seem to discourage these because of the narrower diameter (2 11/16). I was ready to take out the cement chisel but noted that the wax ring plastic flange that came with the toilet ( Kohler Memoirs all in one box including the wax ring) had the same 2 11/16 (maybe 2 3/4) diameter as the inside fit closet flange.
If the plastic flange that came with the toilet makes the inside diameter of the inside fit 3" PVC closet flange shouldn't that work? if I used a bigger closet flange that left a 3" inner diameter wouldn't the wax ring flange still restrict the flow any way? If I change to a wider wax ring the toilet outflow hole is the same diameter anyway.
thanks
