Here's my dilemma. When I turn my shower on to full hot, it's fine. But it's too hot, so I need to back it down a little. When I turn the lever down, instead of just having to back it off a liitle, I have to bach it off almost all the way before there's any change in the water temp. Then when it finally changes I have to turn it back up a ways to get the right temp. In other words, turning the lever does not produce a direct corelation in the cange of the temp. It didn't used to be this way. Also, when I finally have the temp set where I want it, and my wife turns on the water in her sink, the shower water gets scalding hot and when she turns it off the shower stays hot. Again, it didn't used to be this way.
Anyway, I took it apart and everything looks ok. I can't imagine that replacing anything is going to solve the problem, but I don't know what will. I'm open to any suggesstions.
