How to Replace Cartridge in Moen Bathroom Faucet?

1. Gather your tools and materials

Before you begin, gather the following tools and materials:

• Replacement cartridge for your Moen faucet
• Penetrating oil
• Adjustable wrench
• Flathead screwdriver
• Phillips head screwdriver
• Bucket
• Rags

2. Turn off the water supply

The first step is to turn off the water supply to your Moen faucet. This will prevent any water from coming out of the faucet while you are working on it.

To turn off the water supply, locate the shut-off valve for your faucet. This valve is usually located under the sink, near the faucet. Turn the valve clockwise to turn off the water.

3. Remove the old cartridge

Now that the water supply is turned off, you can begin to remove the old cartridge.

To remove the cartridge, you will need to first remove the handle of the faucet. This is usually done by unscrewing the screws that hold the handle in place. Once the screws are removed, you can lift the handle off of the faucet.

With the handle removed, you will see the cartridge. The cartridge is a small, cylindrical-shaped piece of plastic or metal that is located inside the faucet body. To remove the cartridge, you will need to use an adjustable wrench to loosen the screws that hold it in place. Once the screws are loosened, you can pull the cartridge out of the faucet body.

4. Apply penetrating oil to the new cartridge

Before you install the new cartridge, it is a good idea to apply some penetrating oil to the threads. This will help to make the installation process easier.

To apply the penetrating oil, simply spray a small amount onto the threads of the new cartridge. Allow the oil to sit for a few minutes before continuing with the installation process.

5. Install the new cartridge

Now that the old cartridge has been removed, you can install the new cartridge.

To install the new cartridge, simply reverse the steps that you took to remove the old cartridge. First, insert the new cartridge into the faucet body. Then, tighten the screws that hold the cartridge in place. Finally, replace the handle of the faucet.

6. Turn on the water supply

Now that the new cartridge has been installed, you can turn on the water supply to your faucet.

To turn on the water supply, simply turn the shut-off valve counterclockwise. You should now be able to use your faucet as normal.
