FAQ

This cartridge is designed for use with Moen Posi-Temp single-handle tub and shower faucet configurations. It serves as a direct replacement for the 1222 and 1222B cartridge series.
You likely need a replacement if you notice persistent dripping from the showerhead or tub spout, difficulty turning the handle, or if the handle feels loose or fails to properly regulate the water temperature.
To replace this cartridge, you will typically need a screwdriver to remove the handle, a hex key (Allen wrench) for the handle set screw, and a pair of pliers or a cartridge puller to remove the old unit. This kit includes a specialized twisting cap tool to assist in loosening the existing cartridge from the valve body.
Before beginning, ensure you have completely shut off the water supply to the shower valve. It is also recommended to drain any remaining water from the lines by opening the faucet handle after the water is turned off. Inspect the valve body for any mineral buildup or debris before inserting the new cartridge to ensure a proper seal.
Replacing this cartridge is a standard DIY task that typically takes 20 to 45 minutes. The most challenging part is often removing the old cartridge if it has become stuck due to mineral deposits over time; the included removal tool is designed to help break that seal.
