This is the OEM cartridge for Moen's Standard and MoentrolShower Valve. You'll generally need a new cartridge if you are experiencing any of the following:
Moen's Standard and Moentrol Valves are very simple. The cartridge is held in place by a small horseshoe clip. Below you'll find more information on how to remove and install a Moen 1225 Shower Cartridge.
Includes: 1225 Cartridge, Twisting Cap (To Loosen Old Cartridge), Plumber's Grease, Installation Instructions
Compatible With: Moen Standard Shower Valve; Moen Moentrol Shower Valve
The best way to identify if you need a 1225 Shower Cartridge is to remove the Shower Handle and Escutcheon Plate and inspect the valve. The Moen 1225 Cartridge has a distinct look, and would be hard to mistake for another part, especially if you have removed the cartridge already. Be sure to shut off your Main Water Supply before doing any work on the valve.
It is also important to not assume that just because it says Moen on one of the pieces of the plumbing, that it is a Moen. If you know it's definitely a Moen, you can know that a Moen 1225 Cartridge is right for you by observing how the water turns on and how the temperature is controlled.
Moen's 1225 Cartridge turns on by pulling the handle out to turn it on, pushing it in to shut it off and rotating the handle left and right to adjust temperature.
If your shower turns on by rotating the handle, this IS NOT the cartridge for you and you'll want to refer to the Moen Posi Temp Cartridge to repair your valve.
(Please note that this cartridge is not compatible with any other valves than the Moen Standard Valve and Moentrol Valve.)
The 1200 is Moen's original Single Handle Brass Cartridge. In the 1980's, Moen updated to the 1225 and designed it so that a Moen 1225 could replace a Moen 1200 Cartridge. Furthermore, it's a best practice to replace your Moen 1200 Cartridge with a Moen 1225 Cartridge, as it has better performance - like a smoother handle feel and a lower propensity to stiffening up.
