My shower head is dripping. I've had the handle apart twice, replaced the seats/springs, replaced the handle/screw, put in a new "ball" (I don't know what that's called).
I get everything replaced, turn the water back on, and have no leak. I turn the water on, then off, still no leak.
Someone in the house takes a shower, and the leak returns.
Am I doing something wrong, or do I need a plumber for a different problem?
