My tub has a 3 handle setup, one valve stem for hot, one for cold and the diverter valve in the middle. I've replaced the seat washers in all 3 (hot, cold, & diverter) and I've replaced the seats for both hot and cold. It doesn't leak for about 1 week, then begins to leak. I've replaced the seat washers more than once with the same results.

Also when the shower is on, there's a small stream of water that continues to come out of the spout...although I don't think its related, it's also bothersome.

Any ideas to help stop this leak would be helpful.
