Our control which has the six settings does not always stop at each setting. It's almost like some stopping points are wearing out. Some of the settings don't "click" in or stop at the marking. It often appears like it is not switching completely from one setting to the next and often it will leak. For instance, if I switch from both the fixed shower head and the hand shower head both working at the same time to just the hand shower head working, the fixed shower head will still drip a considerable amount of water. If I try to move the handle a little each way, sometimes I can get the drip to stop or slow down. Also some days it seems like each setting works without any problem. One of the things I always notice is it that the stopping points that have the markings for each setting seem to not stop in place where other settings you can feel a definite stopping point.

Another issue is lately when we turn off the shower, it appears that water drains for a longer period of time than it used to from either fixed or hand shower head. I know this because my wife likes to squeegee the shower tiles and now we have to leave the shower for a few minutes and come back when the water stops dripping to finish squeegeeing the tile.

What can I do to fix these issues? Do I need to take something apart and tighten something? Please help!!
