How to Change a Moen Faucet Cartridge: A Step-by-Step Guide

If you are experiencing a leaky or drippy faucet, it may be time to change the cartridge. The cartridge is a small, cylindrical component inside your Moen faucet that controls water flow. Over time, cartridges can become worn or damaged, leading to leaks or reduced water pressure. Knowing how to replace a Moen faucet cartridge can save you money and hassle by avoiding calling in a professional plumber. In this step-by-step guide, we will walk you through the process of changing a Moen faucet cartridge.

Step 1: Gather Materials and Tools

Before beginning the process of changing your Moen faucet cartridge, you will need to gather the proper materials and tools. Here’s what you’ll need:

  • Brand-specific replacement cartridge (if necessary)
  • All-purpose lubricating grease
  • Adjustable wrench
  • Pliers (optional)
  • Phillips or flathead screwdriver (depending on your faucet model)
  • Rag or towel

It is also important to shut off the water supply before beginning any work on your Moen faucet. This can usually be done by turning off the shutoff valves located under the sink.

Step 2: Remove Handle and Escutcheon

Once you have gathered all of the necessary materials and shut off your water supply, the first step in changing your Moen faucet cartridge is removing the handle and escutcheon plate.

1. Find the set screw located on the handle of your Moen faucet (usually located underneath).
2. Loosen the set screw with an adjustable wrench until it comes out completely.
3. Pull the handle straight up and it should come off.
4. Use a screwdriver to remove any screws holding the escutcheon plate in place.
5. Gently pry the escutcheon plate away from the faucet body with a screwdriver or pliers.

Depending on your Moen faucet model, you may need to remove additional components beyond the handle and escutcheon plate to access the cartridge. Be sure to consult your faucet manual or online resources for specific instructions for your particular faucet.

Step 3: Remove Old Cartridge

Once you have removed the handle and escutcheon plate, it is time to remove the old cartridge from the faucet body.

1. Locate the retaining clip that holds the old cartridge in place.
2. Remove the retaining clip by gently prying it up with a flathead screwdriver.
3. Use pliers or another gripping tool to pull the old cartridge straight out of the faucet body. Be careful not to damage any other parts of the faucet while doing so.
4. If necessary, clean any debris or residue from inside the faucet body using a rag or towel.

Step 4: Install New Cartridge

Now that you have successfully removed the old cartridge, it is time to install a brand-new one.

1. Apply all-purpose lubricating grease to the new cartridge’s O-rings.
2. Insert the new cartridge into the faucet body in exactly the same orientation as the old one was situated (consult your manual if necessary).
3. Press down firmly on the new cartridge until it clicks into place.
4. Replace retaining clip onto new cartridge.

Be sure to follow manufacturer instructions closely when installing your new Moen faucet cartridge, as some models may require additional steps or modifications.

Step 5: Reassemble Handle and Escutcheon

With your new Moen faucet cartridge successfully installed, it’s time to put the handle and escutcheon plate back in place.

1. Replace the escutcheon plate onto the faucet body.
2. Reinsert any screws that were removed during step 2 and tighten them securely.
3. Press the handle back onto the faucet body.
4. Tighten the set screw with an adjustable wrench until it feels secure.

Be gentle while reassembling your Moen faucet to avoid damaging any of its components.

Step 6: Test Faucet Operation

After reassembling the handle and escutcheon plate, turn on your water supply and test your newly installed Moen faucet cartridge for functionality.

1. Turn on the water slowly to prevent splashing or leaking.
2. Check that the water is flowing out of both hot and cold handles at full pressure and with no leaks or drips.
3. Check that the hot and cold handles are properly aligned with their corresponding water temperatures.

If everything checks out, congratulations – you have successfully replaced your Moen faucet cartridge!

Troubleshooting Common Issues

Despite following these instructions closely, you may encounter a few common issues when changing your Moen faucet cartridge. Here are some troubleshooting tips:

Leaking After Replacement: If your faucet is still leaking after replacing the cartridge, check for any loose screws or O-rings around the cartridge or replace any worn components like washers.

Difficulty Removing Cartridge: For particularly stubborn cartridges, try using pliers or another gripping tool to gently rock it back and forth while pulling it straight up.

Stripped Screws: If screws become stripped during removal, try placing a thick rubber band over the screw head before trying again – this can often provide enough grip to loosen even stripped screws.

Importance of Regular Maintenance

Replacing your Moen faucet cartridge only becomes necessary when it becomes damaged or worn beyond repair. By regularly cleaning and maintaining your faucet, you can avoid the need for costly replacements altogether. Simple maintenance tasks such as regularly wiping down the faucet, keeping soap scum and hard water stains at bay, and fixing leaks as soon as they occur can all help extend the lifespan of your Moen faucet.


Replеacing a Moen faucet cartridge may seem like a daunting task at first, but it is relatively simple and straightforward with some preparation and careful attention to detail. With this step-by-step guide, you can successfully replace your Moen faucet cartridge yourself and avoid paying for a professional plumber. Remember to shut off the water supply before beginning, gather all the necessary materials, and follow manufacturer instructions closely – in no time, your leaky Moen faucet will be back to working flawlessly.
