One of the slots for the bolts that holds the toilet to the flange is cracked. The flange and drain pipe are both PVC, cemented together. I tried using this internal pipe cutter to separate the flange. It's item
37516 here:The idea is that you work the tool around the circumference of the drain pipe just below the bottom of the flange. The problem is that the blade is about 1/4 inch too small in diameter to get through the wall of the drain pipe. (The thickness of the flange wall gets in the way.) A blade about 1.5" would probably be perfect.
The problem is how to cut through the drain wall completely. The house is on a slab and the bathroom floor is tiled, so repair kits that work by slipping stainless steel rings between the flange and the floor won't work. Zero gap.
The 3" grinding wheels shown here,
Any other ideas for removing the flange/drainpipe?
Thanks,
