If your Moen shower faucet begins to drip water and the faucet handle is difficult to turn, it may be time to replace it. First, you need to remove the old valve cartridge before you can install the new one. It just takes a few tools to take apart your Moen shower valve and it is possible to do this job on your own. It will save you money in the long run, rather than hiring a professional.
Things You'll Need
- Flathead screwdriver
- Needle nose pliers
- Replacement valve cartridge

Shut off the main water supply to the house by turning the valve to the right. The water valve should be located near the shower in an adjacent room or in the basement of the home.
Gently pop off the decorative cap on the faucet handle with a flat screwdriver and do it slowly to prevent damage. Set it in a safe location for later. Loosen the screws on the handle with a flat screwdriver and pull the handle off.
Loosen the screws on the escutcheon plate behind the faucet handle with a flat head screwdriver and pull the plate away from the wall.
Pull out the clip at the front of the valve part with needle nose pliers. Place the plastic removal tool that came with the replacement cartridge on the valve and push it against it. Use the needle nose pliers to twist the tool and the cartridge at the same time. Pull the cartridge out.
Turn on the water supply and test the shower to make sure it works properly.
