Adjustable wrench
Flathead screwdriver
Faucet seat wrench (optional)

Step 2: Shut Off Water Supply

Locate the water supply valves beneath the sink and turn them clockwise to shut off the water supply to the faucet. This will prevent water from leaking during the replacement process.

Step 3: Remove Handle

Locate the set screw on the handle of the faucet. Use a flathead screwdriver to loosen the set screw and pull the handle straight up to remove it.

Step 4: Remove Cartridge Cap

Beneath the handle, you will find the cartridge cap. Use an adjustable wrench to loosen the cap and remove it by hand.

Step 5: Extract Old Cartridge

Grab the old cartridge firmly with your hand and pull it straight out. If the cartridge is stubborn, you can use a faucet seat wrench to extract it.

Step 6: Inspect Faucet Seat

Once the old cartridge is removed, inspect the faucet seat for any debris or damage. If you notice any irregularities, clean the seat using a wire brush or a toothbrush.

Step 7: Apply Plumber's Putty (Optional)

If desired, apply a small amount of plumber's putty to the base of the new cartridge. This will help to create a watertight seal and prevent leaks.

Step 8: Insert New Cartridge

Align the new cartridge with the faucet seat and insert it straight in. Push the cartridge firmly into place until it is fully seated.

Step 9: Replace Cartridge Cap

Screw the cartridge cap back in place by hand, then tighten it further using an adjustable wrench.

Step 10: Reinstall Handle

Align the handle with the cartridge stem and slide it down until it fits snugly. Tighten the set screw to secure the handle.

Step 11: Turn on Water Supply

Turn the water supply valves counterclockwise to restore water flow to the faucet. Check for any leaks around the cartridge cap or handle.

Step 12: Test Faucet

Operate the faucet handle to ensure that it is functioning correctly. Check for any leaks or unusual noises. If everything is working properly, the faucet cartridge replacement is complete.

Congratulations! You have successfully replaced the cartridge in your Moen bathroom faucet. Remember, if you encounter any difficulties during the process, it is always advisable to consult a qualified plumber for assistance.
