Last Updated: June, 2022 | By JULIAN GILL

Facing a repair of your Moen single handle bathroom faucet and feeling a little overwhelmed? Don’t be!  There is help here to make each repair easy, safe, and effective.  Take a look at your task below.

How Do You Take Apart A Moen Single Handle Faucet?

If you need to take your Moen single handle faucet off and want to know the proper order, here are the steps to follow.

  1. Prepare your sink for disassembly: This means you need to turn off the water and drain the pipes.  This should be done before you start on the next step.
  2. Loosen the handle: Using your screwdriver, loosen the handle and then the screw set that attaches the handle to the faucet.  Attach the dome that is still sitting there.
  3. Remove the plastic sleeve: Turn the plastic sleeve counterclockwise with your wrench and remove it
  4. Remove the water flow mechanism: Unscrew the screw holding this mechanism to the faucet.
  5. Take out the ring, washer, and spout: The ring and washer should be easy to remove.  From there, pull the spout out with pliers.

To put it back together, just reverse the process!

How Do You Remove A Moen Single Handle Kitchen Faucet Cartridge?

The good news about removing the cartridge is that you pretty much follow all of the steps as above, but you’ll add one more to it:

  1. Remove the cartridge: After the spout is out, the cartridge should be visible.  Using the cartridge puller, twist it a few times to loosen it and then pull it out.  Be gentle!

Moen Single Handle Kitchen Faucet Cartridge Repair And Replacement Process

When you’re taking a look at the cartridge itself, you’ll need to either consider whether you want to repair it or replace it.

If you are dealing with scaling or build-up, you can simply repair the cartridge.  Soak it in vinegar overnight and then rinse it off.  Inspect it carefully for cracks or breakages.

If you notice that it is very weak, or it is cracked, you will need to replace it in order to make sure that your faucet is working properly.  The only time you can repair a cartridge is if it is build-up.  All other issues should get a replacement.

How To Repair A Leaking Moen Single Handle Kitchen Faucet?

Whenever you are considering a leak, the main things to look at include:

  • How bad is the leak?
  • Where is the leak coming from?

If the leak is minor, you can definitely try a DIY approach.  If it is severe, you will always want to call in a professional! Did you know that the most common cause of a leaking faucet is a worn or missing O-ring?  This is definitely DIY-friendly repair if you are feeling ready for it.  Steps include:

  • Take apart your faucet
  • Remove O-ring
  • Replace with a new O-ring
  • Test for leaks

If the leak is coming from somewhere that is visible, you can often figure out where the leak is actually coming from.  If you’re just noticing water damage in the area of your faucet, though, a professional is, again, the right call.
