Can anyone help me id this shower control. It is about 19 years old. Hardware is solid and well constructed. The rest of the house is Moen, so I expect it to be of similar quality.
The letters "SHWR" and the number 7105 or 7106 are cast on the mixing valve. I can't tell if it is 7105 or 7106.
It is difficult to pull out and push in the handle. I think I need to replace the cartridge if I can determine the manufacturer.
Thanks for you help
