How to Change a Moen Cartridge

Moen cartridges are a common type of faucet cartridge, and they are relatively easy to replace. Here are the steps on how to change a Moen cartridge:

Tools and Materials Needed:

- Adjustable wrench

- Philips head screwdriver

- Replacement Moen cartridge

- Plumber's putty

- Paper towels

Instructions:

1. Turn off the water supply: Locate the shutoff valves under the sink and turn them clockwise to turn off the water supply to the faucet.

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

3. Remove the old cartridge: Use an adjustable wrench to loosen and remove the retaining nut that holds the old cartridge in place. Once the nut is removed, pull the cartridge straight out of the faucet body.

4. Apply plumber's putty: Apply a thin layer of plumber's putty around the base of the new cartridge to create a water-tight seal.

5. Install the new cartridge: Insert the new cartridge into the faucet body and hand-tighten the retaining nut. Use the adjustable wrench to tighten the nut until it is snug.

6. Reattach the faucet handle: Replace the faucet handle and secure it with the screws that you removed earlier.

7. Turn on the water supply: Turn the shutoff valves counterclockwise to turn the water supply back on.

8. Check for leaks: Turn on the faucet and check for any leaks. If there are any leaks, tighten the retaining nut or adjust the plumber's putty until the leak stops.

Tips:

- When removing the old cartridge, be careful not to drop any parts into the drain.

- If the old cartridge is stuck, you may need to use a penetrating oil to loosen it.

- Be sure to purchase the correct replacement cartridge for your Moen faucet.

By following these steps, you can easily replace a Moen cartridge and get your faucet working properly again.
