My sympathies; I've been having random plumbing problems ever since this summer's fun with the well. Apparently, when the old well caved in, it dumped a load of sand 'n shredded plastic into the water system which is slowly flushing itself out now. Periodically, I have to disassemble a plumbing fixture and clean it. "Periodically" started out meaning "daily"; down to about once every couple weeks now.
