In the 1980's Moen changed their Standard Valve to a Pressure Balancing Valve called Moentrol. While the Moentrol takes the same cartridge (1225) as the Standard Valve, the screw positions on the Moentrol trim is different.
The good news if you have a Standard Valve is you can use a Moentrol Trim without having to change the valve. The bad news is you have to buy this Shower Adapter Kit to convert your screw positions to the newer trim's set up.
The Moen Shower Adapter Kit easily attaches to your existing valve with 2 screws, allowing you to install a Moentrol Trim Kit without paying hundreds of dollars for a plumber to change out your entire shower valve!
If your screw positions are at 5 and 7 you'll need this kit. If they're at 7 and 1 you will not need it.
(Please note this is not compatible with the Posi Temp valve, nor will it work with any other valves except for the Moen Standard Valve. It does not change the functionality or performance of the valve either.)
