Shut off the Water Supply

Before you start, take a deep breath and make sure you’re ready to take the plunge – figuratively speaking – and shut off the water supply. Turning off the water will prevent any water damage risks and ensure your safety while you replace the o-ring on your Moen kitchen faucet.

There are a few steps you should take before shutting off the water:

  • Locate the main water shut-off valve. This is typically found in a utility room, garage, or basement.
  • Turn the valve clockwise until it’s fully closed.
  • Open all of the faucets in the house to release any remaining pressure in the pipes.

Once the water has been shut off and all of the faucets have been opened, you’re ready to begin replacing the o-ring. Make sure to take all necessary precautions and wear protective gear to ensure your safety. Refer to the diagram included with your Moen faucet for detailed instructions on how to replace the o-ring.

Remove the Handle

Carefully remove the handle from the faucet so you can access the o-ring.

Begin by lubricating the handle, then loosen the screws that are holding the handle in place. You may have to use a wrench or a screwdriver to get the screws to loosen.

Once the screws are loose, you can then pull the handle off the faucet. Be careful to note the orientation of the handle so that you can replace it in the same position.

Once the handle is removed, you should be able to access the o-ring and you’ll be ready to replace it.

Take Out the Old O-Ring

Pull out the old o-ring and throw it in the bin – it’s time to give your Moen kitchen faucet a fresh start.

First, use a pair of pliers to take out the old o-ring. Make sure to keep it in one piece, as this will be useful for measuring the new o-ring when you buy it.

If the old o-ring is stuck, you can use some lubricant to help it come out. It’s important to use a lubricant specifically for o-rings, as this will help reduce the chance of leaks when you install the new o-ring.

Once the old o-ring is out, you can discard it and move on to installing the new one.

Install the New O-Ring

Give your plumbing a much-needed upgrade and give your home a fresh look by installing a new o-ring! To do this, gather the following materials and tools:

  1. The new o-ring
  2. Plumber’s lubricant
  3. A flat-head screwdriver
  4. A Phillips-head screwdriver

Start by lubricating the o-ring with plumber’s lubricant. This will prevent it from sticking to the faucet and make installation easier.

Then, place the o-ring around the faucet stem and tighten the screws that secure it. Make sure the o-ring is tightly secured, as this will create a seal that prevents water from leaking.

Finally, wipe away any excess lubricant, and your faucet is ready for use!

Reassemble the Handle

Now that you’ve installed the new seal, it’s time to reassemble the handle and get your faucet up and running again.

Start by taking your handle and aligning the holes with the valve housing. The valve housing is the top part of the faucet where the handle attaches. Once aligned, insert the screws into the holes and tighten with a screwdriver until secure. Make sure not to overtighten the screws as this can cause damage.

Next, locate the cam assembly, which is a metal piece with a hole in the center. This will fit onto the valve stem, which is the part of the faucet that moves when you turn the handle. Align the cam assembly over the valve stem and secure with the screws that were included with the faucet. Make sure to tighten the screws firmly, as this will ensure the handle does not come loose.

Finally, reattach the handle to the valve housing and secure with the screws.

Your faucet is now repaired and ready for use.

Turn the Water Supply Back On

After securing the handle, it’s time to turn the water supply back on and start using your faucet again. To prevent any leaks, start by turning on the water supply valves located beneath the sink. Make sure to do this slowly, as turning on the water too quickly can cause water pressure problems.

Then turn the handle above the sink to the ‘on’ position. Check the connections for any visible leaks and make sure the handle is securely fastened.

Lastly, turn on the faucet and check for any leaks or drips. If no leaks are present, you’ve successfully installed your new Moen kitchen faucet! Make sure to clean up any excess debris from the installation and enjoy your new faucet.
