How To Repair A Leaking Moen Kitchen Faucet

Moen is one of the most reputable brands of cartridge faucets.

Since the founder, Al Moen, founded this company in 1956, Moen has become a household name in faucet production.

Because of their distinctive design, Moen kitchen faucet repair is made easier because you won’t have to waste time looking for numerous faucet models. It’s a cartridge faucet if it’s a Moen.

That’s not to say Moen doesn’t have a dizzying array of faucet models available. It most certainly does.

It is important to know what kind of faucet you have so that you can get the appropriate replacement components when a Moen kitchen faucet leaks.

Some of the fixes frequently entail replacing the Moen kitchen faucet cartridge and the rubber parts that go with it.

You can always find the specific part of a Moen kitchen faucet on their main website.

If your Moen kitchen faucet is leaking, you should try to fix it ASAP because the leakage issue may escalate into something costly later.

In this article, the various steps to fix your leaking Moen kitchen faucet are discussed. Let’s take a walk.

Steps To Repair Leaking Moen Kitchen Faucet (Single Handle) And Moen Faucet Leaking From The Base

Tools Needed Before Getting Started

  • Soft Brush
  • Screwdriver
  • Allen Wrench
  • Flathead screwdriver
  • Adjustable wrench pliers
  • New Washer
  • To reduce water pressure, shut off the water valves under the sink and open the faucet
  • With a flat-head screwdriver, find the screw cap covering the faucet handle, and pull it out to reveal the set screw holding the handle in place. Typically, the Moen logo is on the hat.
  • Pull off the handle after loosening the set screw with a 1/8-inch Allen wrench. If it doesn’t come off easily, give the scale holding it on a couple of mild hits with a hammer to break it away.
  • Use tongue and groove pliers to unscrew the retaining nut holding the cartridge in place. You may also use a retention pin to hold the cartridge in place. Use a flat-head screwdriver to solve this problem while being careful not to drop it down the sink.
  • If your faucet is old, the cartridge may be difficult to get out. If that’s the case, you’ll need to rent or buy a cartridge puller. Otherwise, grab the valve stem with a pair of pliers and wiggle it side-to-side until it pops out.

b. Check the handle to see damaged parts and clean or replace the washer

The function of a washer is to close or open the water flow in the faucet.
As time goes on, mineral deposits can accumulate in your washer. When the accumulation of minerals becomes too great, your washer won’t function properly and your faucet may start to leak.

Mineral buildup can cause a gap to form around the faucet, which means the washer won’t be able to shut off the water even when the handle is in the “off” position.

You need to clean the washer in this scenario. Vinegar is the finest solution for removing mineral buildup.

Mix the same amount of water and vinegar. Now put the washer into the mixture for a few hours.

It will remove all buildup from the washer and make it function properly again.

However, if the washer is damaged, cleaning it up won’t solve the issue. You will need to purchase a new Moen kitchen faucet part.

Once you’ve completed the repairs on the washer, put all the pieces back in their rightful places and give the faucet a test run to make sure everything is functioning correctly.

Fixing a Leaky Moen Double Handle Kitchen Faucet

  • Tools Needed
  • A screwdriver (preferably Philips).
  • A flathead screwdriver
  • A pair of pliers
  • A new washer (the same size as the old one)
  1. Firstly, shut off the water supply to the tap.
  2. Use a Philips screwdriver to remove the handle.
  3. Remove the cap from the valve stem with a flathead screwdriver.
  4. The valve stem would be retained with a clip. The retaining clip can be eliminated with the use of pliers.
  5. Now that the valve stem is unlocked, you can remove it from the faucet body.
  6. Check out the washer’s state of repair. Replace it if it’s worn out or damaged.
  7. Gently take out the old washer and fit a brand-new washer onto the valve stem. All parts should be reattached, and everything should be securely tightened.
