How to Install Moen Cartridge Valve

No matter which type of Moen faucet valve you pick, the installation process is similar for both types. The Moen Posi-Temp Shower Cartridge valve is designed to prevent scalding by regulating the differences in pressure and temperature when other fixtures in the plumbing system are used simultaneously. Therefore, here is a brief step-to-step guide on how to install a Moen cartridge valve;

➥ Turn off the hot and cold-water closing valves. If there are shower valves, turn off the main water valve. Open all the faucets to drain any excess water from the shower system.

➥ Remove the faucet handle. The Moen faucet handle has either a Philips-head screw or Allen screw holding on it.

➥ Behind the faucet handle is a plastic piece held by a Philips screw. Once the screw is removed, slide off the chrome sleeve surrounding the cartridge.

➥ Pull straight up the brass clip holding the cartridge using a pair of pliers. Lastly, pull out the cartridge from the faucet valve.

➥ Install the new cartridge to the wall valve. The cartridge is usually marked H and C to avoid installing it upside down.

➥ Reinstall the handle and turn on the shower.
