Understanding Moen Kitchen Faucets

Moen kitchen faucets work well and are easy to use. They come in different styles, but all have the same important part called the cartridge. This part controls the water flow and temperature when you turn the handle.

Reasons to Replace Cartridges

Your Moen kitchen faucet’s cartridge may need to be changed if it’s causing leaks, poor water control, or inconsistent water temperature. If water is dripping from the faucet even when it’s off, the cartridge may be the problem. If you’re having trouble controlling the water flow or temperature, a worn-out cartridge may be to blame. And if the water’s temperature continues to vary unexpectedly, replacing the cartridge will help restore reliable temperature control.

Tools Required for Cartridge Replacement

Before replacing the cartridge in your Moen faucet, you will need a flexible wrench and either a flathead or Phillips screwdriver. You should also have a plumber’s lubricant, a replacement cartridge specific to your faucet’s design, and a cloth or towel.

Steps to Replace Cartridge on Moen Kitchen Faucet

Let’s now go over how to replace the cartridge on your Moen kitchen faucet step-by-step:

Step 1: Shut off the Water Supply

Before fixing your faucet, turn off the water supply. Find the valves under the sink and turn them clockwise to close them. This will prevent water from leaking while you work on the faucet.

Step 2: Remove the Faucet Handle

To get to the cartridge, remove the faucet handle. Depending on the model, the handle may be held in place by a screw or a decorative cap that can be removed with a flathead screwdriver. Once exposed, use a screwdriver to remove the handle screw. Be careful when lifting the faucet handle off after removing the screw.

Step 3: Access the Cartridge

After taking off the handle, you’ll see a pretty plate or collar around the cartridge. To get to the cartridge, either unscrew or push off the collar.

Step 4: Remove the Cartridge

Use pliers or a wrench to turn the cartridge stem counterclockwise and remove it. If it’s stuck, apply lubrication or force. Be careful not to damage nearby components.

Step 5: Install the New Cartridge

Put the new cartridge in the Moen kitchen faucet. Match the grooves in the faucet with the notches on the cartridge. Once it’s in the right place, turn it clockwise to tighten it.

Step 6: Reassemble the Faucet

Put the faucet handle and decorative collar back on and make sure they are tight. If needed, tighten the screws or change the decorative cover. Turn on the shut-off valves under the sink to get the water running again. Test the faucet to make sure there are no leaks and that the water is working properly.


Replace the cartridge on your Moen kitchen faucet by following these steps. Keep your faucet working well by doing regular maintenance and changing worn-out parts when needed. Follow Moen’s directions for your faucet model to be safe.
