1. Turn off the Water

You cannot repair a shower faucet when there is full water pressure in the pipes. The first to do therefore is to turn off water supply to the shower (and possibly the entire house) and drain that which is already in the pipes.

2. Remove the Faucet Handle

The faucet handle is attached to the cartridge using a screw on its underside. To access the cartridge you will first need to remove the handle. While most Moen handles will look this way, there also other variations. One way or the other the handle will have a screw somewhere.

3. Remove the Old Faucet Cartridge

Once the faucet handle is out, you will see a plastic holder (usually black) connected to the cartridge using a Philips screw. Remove the handle holder using the Philips screwdriver.

4. Install the New Cartridge

Prior to installing the new cartridge, it is a good practice to first clean the valve. Use an old toothbrush, to scrub off calcium and other mineral deposits. If there are lots of debris inside the valve, turn on the water slowly to flush out the debris. This will prevent leaking from the new cartridge.

5. Test the New Moen Shower Cartridge

Turn on the water supply to the shower and check for leaks when the faucet is turned off. Open the water and let it run and then turn it off. Check if the faucet is shutting off precisely.
