I have two separate issues. The first issue I have is when the shower is knobs are turned on they leak from behind the knob (?) making one stream of really hot water dripping on my foot, and a stream of ice cold dripping on the other. How can I fix this?
My second issue is when off my faucet continues to drip, I have replaced, handles, stems, gaskets, seats etc. Once I replaced them the leak was fixed for awhile, then a couple months later it started again. I checked and the gasket at the end of the cold water stem was missing (I have no idea where it went), so I replaced it, and it stopped leaking again. It's been two months and now it's leaking again, what am I doing wrong?
