Replace Cartridge Moen Bathroom Faucet

Moen bathroom faucets are known for their durability and stylish designs. However, even the most well-made faucets can experience issues over time. One common problem is a leaking cartridge. If your Moen bathroom faucet is leaking, it is likely due to a worn-out cartridge.

Replacing a Moen bathroom 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 You'll Need:

Phillips screwdriver
Adjustable wrench
New Moen cartridge
Bucket
Rags

Step 1: Gather Your Tools and Supplies

Before you begin, gather all of the tools and supplies you will need. This will help you work efficiently and avoid any delays.

Step 2: Turn Off the Water Supply

Locate the water supply valves under the sink and turn them off. This will prevent water from flowing into the faucet while you are working.

Step 3: Remove the Handle

Use a Phillips screwdriver to remove the screws that hold the handle in place. Once the screws are removed, pull the handle straight up to remove it.

Step 4: Remove the Cartridge Nut

Use an adjustable wrench to loosen the cartridge nut. The cartridge nut is located behind the handle.

Step 5: Pull Out the Old Cartridge

Once the cartridge nut is loose, you can pull the old cartridge straight out of the faucet body.

Step 6: Insert the New Cartridge

Insert the new cartridge into the faucet body. Make sure that the new cartridge is aligned properly.

Step 7: Tighten the Cartridge Nut

Use an adjustable wrench to tighten the cartridge nut. Do not overtighten the nut.

Step 8: Reinstall the Handle

Push the handle back onto the faucet body. Secure the handle with the screws.

Step 9: Turn On the Water Supply

Turn on the water supply valves under the sink. Check for leaks around the handle and the base of the faucet.

Make sure that you have the correct cartridge for your Moen bathroom faucet.
If the cartridge nut is stuck, you can use a penetrating oil to loosen it.
