: I needed to shorten my roughed in ABS shower drain pipe to fit a 2" ABS Oatey drain. In my effort to shorten the pipe by 7/8", a small piece of the pipe chipped off leaving an uneven jagged top edge. Even though the Oatey drain has 3/4" before it "seats" on the the inner rim seat, which would easily cover the uneven edge, I'm reluctant to install the drain without a perfectly smooth and level drain pipe top edge. If I try again and cut below the jagged edge I'll be too short for my plywood floor. Any suggestions on what to do, short of hiring a plumber? Also, When I test-fitted the Oatey drain over the ABS drain pipe it was extremely tight and I wasnt sure I'd be able to push the drain down the 3/4" so that it would be "seated" on the inner rim. Will the ABS solvent melt the ABS so that the drain will easily slide down the pipe and seat?

You can use a Dremel tool with the appropriate disc blade to cut the ABS from the inside of the pipe, the tool is affordable if you don't already own one.
ABS solvent once applied will allow the shower strainer to slide over the ABS pipe, a dry fit could bind.
