How to Change a Cartridge in a Moen Bathroom Faucet

Replacing a cartridge in a Moen bathroom faucet is a relatively simple task that can be completed in under an hour. By following these step-by-step instructions, you can easily restore your faucet to proper working order.

Tools and Materials

Adjustable wrench
Phillips screwdriver
Moen replacement cartridge (compatible with your faucet model)

Step 1: Turn Off the Water Supply

The first step is to turn off the water supply to your faucet. Locate the water supply valves beneath the sink and turn them clockwise to close them.

Step 2: Remove the Handle

Use the Phillips screwdriver to remove the screw located at the base of the faucet handle. Once the screw is removed, pull the handle straight up to detach it from the cartridge.

Step 3: Remove the Aerator

Next, remove the aerator by unscrewing it counterclockwise. The aerator is located at the tip of the faucet spout.

Step 4: Unscrew the Retaining Nut

Use the adjustable wrench to unscrew the retaining nut located beneath the aerator. This nut holds the cartridge in place.

Step 5: Remove the Cartridge

Once the retaining nut is removed, you can pull the old cartridge straight out of the faucet body. Inspect the cartridge for any signs of wear or damage.

Step 6: Install the New Cartridge

Insert the new cartridge into the faucet body and push it in firmly. Align the cartridge's notch with the corresponding notch in the faucet body.

Step 7: Tighten the Retaining Nut

Use the adjustable wrench to hand-tighten the retaining nut onto the faucet body. Avoid overtightening, as this can damage the cartridge.

Step 8: Reinstall the Aerator

Screw the aerator back onto the faucet spout by hand-tightening it clockwise.

Step 9: Reinstall the Handle

Align the handle with the cartridge's notch and push it down to engage it. Secure the handle by tightening the screw at its base.

Step 10: Turn On the Water Supply

Turn the water supply valves under the sink counterclockwise to open them. Check for any leaks around the faucet base and handle.

Conclusion

Congratulations! You have successfully changed the cartridge in your Moen bathroom faucet. By following these instructions carefully, you have saved yourself the cost of calling a plumber and ensured that your faucet is functioning properly.
