SOURCE: Repair cartridge in Moen Monticello single handle lavatory faucet

After some additional experimenting, contrary to information I was previously able to gather, I discovered that the white plastic retainer doesn't (in this type of Moen faucet) actually screw off but rather is held in place by a spring clip inserted from the rear of the retainer (toward the wall side of the basing). Simply sticking a small screwdriver in the opening (approx. 45 degrees downward) and tipping the screwdriver toward the front of the faucet, snaps the spring clip out through the opening.
The plastic retainer than lifts off. Note: the flat sides on the retainer suggest that a wrench will be needed but such is not the case.

SOURCE: Moen kitchen faucet model 7430 leak

cartridge does not stop that type of leak. If it is leaking from around the base of the spout it is o-rings that are the problem that are onthe valve after you pull the spout all the way off.

SOURCE: How do I remove the aerator on a moen pull out

It should just unscrew. You might need some needle nose pliers as the aerator may be slightly recessed.

    Moen has a diverter built in that will need to be replaced.

    use the same steps as when you replaced the cartridge, but this time you will need to remove the spout, there is a small diverter, you will see it when spout is removed.

    take this part with you to the hardware store, along with the O Rings from the spout, as they will need to be replaced also

    I cant stop my Moen single lever kitchen faucet from leaking. how can I fix it?


    1. If it's "leaking" from the body then, the O-Rings between the body of the faucet got gunked up with minerals from your water. This interferes with the seal.
    The answer is to take some grit cloth/very fine sandpaper and clean the inside of the spout body. Wipe clean. I would also suggest replacing the O-Rings on the faucet body, but at the very least wipe the O-rings and faucet body clean.
    THEN: lubricate the inside of the spout body AND the O-Rings with silicone grease. It's translucent and readily available and the only thing I would ever use for a faucet repair. NOT plumber's grease, NOT WD-40.
    Reassemble and enjoy.

    2. If it's dripping, the you need a new cartridge. You can get them for FREE from the hardware store if you have the old cartridge to trade them. The problem is that Moen cartridges are water-sealed into place and you need a special tool to break that water seal. The special tool (just a tiny piece of specifically shaped plastic, really) comes, you guessed it - with the new cartridge.
    Two possible solutions: a) bite the bullet and just buy the cartridge (~$25) or buy a Moen cartridge puller, usually available from the hardware store as well for about the same price. Ask, they might even lend you one.
    The point of whichever tool you end up with is to rotate the cartridge itself inside the faucet body to break the water seal so that you can pull it out with a set of pliers. There will be a retaining clip to pull out as well.
