I had a leaking bottom seal for my first floor half bath toilet, buckling linoleum tiles. I took up the linoleum and 0.7 in composite board that sits on the primary subfloor.
As part of this renovation I used an oscillating saw to cut away the upper portion of the toilet flange from the 3"PVC pipe. I now have the female portion of the flange to contend with in replacing the flange.
I've tried a little using a chisel to remove outer portion of the flange, but it's slow going and I haven't made any real progress.
Is it easier to just cut the PVC from below and use a female-female coupler?
Additionally, what kind of saw should I use? I assume the cut should be pretty straight and without void space.
