Yaay! I fixed the AC drainage issue (at least I think I did). It took $55.09 (actually $51.10 if you don't count the mistake the person made in ringing it up that I just now noticed), a hacksaw, several plastic connectors, 10 feet of 3/4 inch washer hose, and PVC cement. I cut out the old piping that was put in by a blind plumber with balance problems (I put a level on the pipe and yep, it really did try to drain uphill) and replaced the 5 right angle bends with a length of flexible hose. It seems to work fine and, except for the nasty ceiling tile, you wouldn't know anything had been changed. I didn't even hurt myself! I still think the HVAC system needs to be replaced sooner rather than later, but at least it should stop dripping for a while.
