How To Replace Cartridge On Moen Kitchen Faucet

When it comes to kitchen faucets, Moen is a trusted and popular brand known for its durability and functionality. Over time, however, even the best faucets may experience issues such as leaks or reduced water flow. In many cases, the problem can be traced back to a faulty cartridge. The cartridge is a crucial component of the faucet that controls the flow and temperature of the water. If you’re experiencing any issues with your Moen kitchen faucet, replacing the cartridge may be the solution. In this article, we will guide you through the process of replacing the cartridge on a Moen kitchen faucet.

1. Gather the necessary tools and materials

Before you begin, make sure you have all the tools and materials you’ll need for the job. Here’s a list of what you’ll typically need:

  • Adjustable wrench
  • Phillips screwdriver
  • Replacement cartridge (make sure it’s compatible with your Moen faucet model)
  • Plumber’s grease
  • Old towel or rag

2. Turn off the water supply

Before you start working on your faucet, it’s important to turn off the water supply. Look for the shut-off valves under the sink and turn them clockwise to shut off the water. Once the water is off, turn on the faucet to release any remaining water in the lines.

3. Remove the handle

The next step is to remove the handle of your Moen kitchen faucet. The handle is usually attached with a screw located either on the top or under a decorative cap. Use a Phillips screwdriver to remove the screw and then lift off the handle.

4. Remove the cartridge

Once the handle is removed, you’ll have access to the cartridge. Depending on the model of your Moen faucet, the cartridge may be held in place by a retaining nut or a clip. Use an adjustable wrench or pliers to loosen and remove the retaining nut or clip. Once it’s loose, you should be able to pull out the cartridge.

5. Install the new cartridge

Now it’s time to install the new cartridge. Before inserting it, apply a thin layer of plumber’s grease to the O-rings on the cartridge. This will help ensure a smooth installation and prevent leaks. Insert the cartridge into the faucet body, making sure it’s aligned properly. Use the retaining nut or clip to secure the cartridge in place.

6. Reassemble the faucet

With the new cartridge in place, it’s time to reassemble the faucet. Start by reattaching the handle and tightening the screw. Make sure the handle is properly aligned and functions smoothly. Turn on the water supply and test the faucet for any leaks or issues. If everything looks good, you’re done!
