T'was the night of the great PVC flood.....
There's nothing quite like waking up to the sound of water dripping from the ceiling in one's bedroom closet. After much panic, frantic moving of clothes, and laying of towels, I found the cause of the leak to be a clogged PVC pipe leading from the air-conditioner's drainage pipe. Removed the pipe, flushed several ounces of particles out with the downstairs hose, and all's well again. Of course, now it's almost 4 am, and the house is big mess of sopping towels, and mounds of clothes, but that'll have to wait until we get some sleep.
