How to Change a Moen Bathroom Sink Faucet Cartridge

Replacing a Moen bathroom sink faucet cartridge is a relatively simple task that can be completed in about 30 minutes. Here are the steps on how to do it:

Tools and Materials

Adjustable wrench
Phillips head screwdriver
New Moen faucet cartridge

Step-by-Step Instructions

1. Turn off the water supply - First, you need to turn off the water supply to the sink. There are usually two shut-off valves under the sink, one for hot water and one for cold water. Turn both valves clockwise to turn off the water.

2. Remove the faucet handle - Next, you need to remove the faucet handle. Most Moen faucets have a plastic cap that covers the handle screws. Use a Phillips head screwdriver to remove the cap. Once the cap is removed, you will see two screws that hold the handle in place. Remove the screws and then pull the handle straight up to remove it.

3. Remove the cartridge retaining nut - Once the handle is removed, you will see a large nut that is holding the cartridge in place. Use an adjustable wrench to loosen the nut and then remove it by hand.

4. Remove the old cartridge - Once the retaining nut is removed, you can pull the old cartridge straight out of the faucet body. Be careful not to lose the small O-rings that are on the cartridge.

5. Install the new cartridge - Take the new cartridge and insert it into the faucet body. Make sure that the O-rings are in place and that the cartridge is fully seated.

6. Install the cartridge retaining nut - Once the new cartridge is in place, you can install the cartridge retaining nut. Tighten the nut using an adjustable wrench until it is snug. Do not overtighten the nut.

7. Reinstall the faucet handle - After the cartridge retaining nut is tightened, you can reinstall the faucet handle. Insert the handle onto the faucet body and then tighten the screws to secure it. Replace the plastic cap over the screws.

8. Turn on the water supply - Finally, turn on the water supply to the sink and check for leaks. If there are any leaks, tighten the cartridge retaining nut or the faucet handle screws until the leaks stop.

Replacing a Moen bathroom sink faucet cartridge is a simple task that can be completed in about 30 minutes. By following these steps, you can save yourself the cost of hiring a plumber.
