I need to replace a toilet flange cemented inside a 90 degree 3" sched 40 elbow. This elbow mates another joint immediately so cutting the elbow off would be difficult. All is accessible from below.
I saw a plastic "two-finger" flange made by Jones-Stephens that will fit inside the 3" pipe. It has two rubber gaskets that seal when inserted. Could I cut just below the top of the existing flange and insert the new one?
My concerns:
1. The insert will cause a reduction of i.d. Could it restrict flow?
2. The 90 degree elbow is unsupported from below so nothing will hold the gasketed joint rigid.
Opinions? Advice?
