How to Replace a Moen Kitchen Faucet Cartridge Step by Step

Step 1: Turn off the water

It is critical to switch off the water supply to your Moen kitchen faucet before beginning the cartridge replacement operation. This will keep water from flowing into the faucet while you work on it, which is both inconvenient and perhaps dangerous. You can switch off the water flow to your kitchen faucet in two ways.

Turn off the main water valve under the sink

The main water valve, which is normally positioned under the sink, controls the flow of water throughout the house. Simply crank the valve clockwise until it is in the “off” position to turn it off.

Turn off the water supply to your entire house

If you can’t find the main water valve, you can shut off the water supply to your entire house. This is typically accomplished by turning off the main shut-off valve, which is normally placed near the water meter or near the street.

Turning on the faucet and checking for water flow is an excellent way to double-check that we have switched the water supply off. If water still flows from the tap, you may need to turn it off again.

Turning off the water flow allows you to work on the faucet without interruptions or accidents. After you’ve turned off the water, you’re ready to move on to the next step replacing the cartridge in your Moen kitchen faucet.

Step 2: Remove the Handle

We must remove the handle next in order to replace the cartridge in your Moen kitchen faucet. This will allow you to gain access to the retainer nut that secures the cartridge. A screw situated beneath the handle normally holds it in place. Here’s how to take the handle off:

Find the screw: Locate the screw behind the handle and determine the type of screwdriver required to remove it. The screws on most Moen kitchen faucets are either Phillips or hex.

Take out the screw: Remove the screw with the appropriate screwdriver by twisting it anticlockwise. The screw may be tight and difficult to remove depending on the age and condition of your faucet. If this is the case, you can loosen it with a pair of pliers.

Remove the faucet handle: Once the screw has been removed, gently remove the faucet handle. It may be necessary to wriggle the handle slightly to free it from the faucet’s body.

You may reach the retention nut that holds the cartridge in place by removing the handle. This is a key stage in the cartridge replacement process, so take your time and remove the handle gently. If you run into any problems, it is usually a good idea to seek the help of a professional plumber.

Step 3: Remove the Retainer Nut

With the handle removed, the next step in replacing the cartridge on your Moen kitchen faucet is to remove the retainer nut. The retainer nut holds the cartridge in place and must be removed in order to access the cartridge itself. Here’s how to remove the retainer nut:

Locate the retainer nut: The retainer nut is located beneath the handle and is usually silver or chrome.

Use pliers: Use a pair of pliers to grip the retainer nut and turn it counterclockwise to loosen it. You may need to apply some force to loosen the nut, so be sure to grip it firmly with the pliers.

Remove the retainer nut: Once the retainer nut has been loosened, you can remove it by pulling it straight out of the faucet body.

By removing the retainer nut, you will have access to the cartridge itself. This is an important step in the process of replacing the cartridge, so be sure to take your time and remove the nut carefully.

Step 4: Discard the Old Cartridge

After removing the retainer nut, you can pull the old cartridge out of the faucet body. If the cartridge becomes trapped, a pair of pliers can be used to free it.

Step 5: Replace the Cartridge

You can now install the new cartridge after removing the old one. Ascertain that the new cartridge is the correct one for your Moen kitchen faucet. If you are unsure, you can find a list of compatible cartridges on the manufacturer’s website. Insert the correct cartridge into the faucet body and tighten the retainer nut by turning it clockwise.

Reattach the Handle in Step 6

The last step is to reattach the faucet handle. Check that the handle is securely fastened and tighten the screw you removed in step 2.


Replacing the cartridge in your Moen kitchen faucet is a simple and inexpensive way to repair a leaky faucet. You can get your kitchen faucet working like new in no time if you follow the procedures given in this article.
