We have a wall mounted shower head as well as a ceiling mounted shower head. Suddenly the turning valve for the wall mounted head does not work, only the ceiling one does. Is this stripped. Can it be repaired with a marble wall? I have a photo if needed. Thank you ahead of time. Patrick
The mixing valve is in the handle that turns the water on. You don't need to take down the wall to get at it. The handle come off including any cover plate and the valve is right behind it. Be careful not drop/lose any screws or washers. They are small. The home center sells replacements for certain brands so get that information.
