I glued in a 2" pipe to the drain and it did not quite butt up against it but worse than that when I attached the pipe to the flange there is a gap of about 3/8". The parts all dry fit no problem. I guess I didn't move fast enough or used too much PVC cement. My question is will this leak? Do I have to pull it out and start over as this would involve removing a partial wall and the floor itself. Help!
