Great source of invaluable information....
I am about to lay porcelain tile in a bathroom where vinyl had been previously. The PVC flange now "floats" just above the 1/2" plywood underlayment. I say floats because the underlayment was cut around the flange and not placed under it. The flange is not secured to the 3/4" plywood subfloor that is below the underlayment either. I plan to use hardibacker and then the tile over the 1/2" plywood underlayment thus raising the new floor about 1/2" over the existing flange. From what it sounds like the best option is to cut out the old flange, using a drill bit designed to cut from inside the soil pipe, lay the cbu and tile, then install a new flange on top of the tile and fasten it to the 3/4" subfloor? Does that sound right? Also how far in/down should I cut out the old flange? I can't really tell where the flange ends and the pipe begins.
Sorry for the long post....any help would be greatly appreciated.
Thanks, Doug
