I have a customer who called me the other day and told my that they are having trouble with the Kohler shower valve in their master bath. They had it installed about 5 years ago, and ever since the pressure balance unit in it seems to go bad. It was replaced twice before me...and now it's gone bad again about 6 weeks after I installed it. I'm not sure of the model number but it is black plastic with o rings for both hot and cold sides that get squeezed between it and the back inside of the shower valve. You then bolt the mixing cap over it. Has anyone experienced this problem where as time goes on you have to turn the handle farther and farther to get hot water?
