Yeah. I found a bit of a leak under my kitchen sink. At first, I felt it was just a bad joint on the P-trap. Having had a closer look at it, I realize that the P-trap isn't a conventional P-trap. Somebody manufactured their own in such a way that it doesn't really work with any standard sink drain. The leak has to do with trying to connect standard 1.5" drain pipe to 2" ABS built such that one of the junctions is always under water. I'll never get that sealed well enough with just a compression coupling, so I need to...do something else. I just haven't figured out quite what I'm going to do, yet. I could either extend the 2" ABS to move the joint higher, or replace the whole P-trap arrangement with conventional stuff. I kind of like it, because the oversized P-trap is very clog-resistant.
