You should be able to remove the lever by inserting a slotted screwdriver between the lever and the round base and twisting the screwdriver a little. Work your way round the lever doing the same thing. The lever should break free. Then lift or twist the round base to remove it and you'll see the nut you need to remove to remove the valve stem.

This is a 20+ year old Moen fixture that has a slow drip on the hot side. I'm trying to replace the cartridge to fix it.

Anyone know how to get this cartridge out of the faucet? (the white plastic part).

Ive tried channel locks. I tried by hand. I also tried to locate a notch to slip a small flathead screwdriver in to ply it up (saw that on YouTube) but not seeing that notch either.

r/Plumbing on Reddit: Moen bathroom faucet handle replacement
October 4, 2024 -

This faucet set is 3 years old. Always felt like it took too much effort to turn. Now the wholehandle base is turning and takes even more effort to turn on and off. I am somewhat handy but not experienced in plumbing repairs. Any links, comments and advice is very much appreciated.

Questions:

  • I understand lifetime warranty for Moen fixtures. I no longer have the packaging. How do I find out the model number? Will moen replace it?

  • how do I repair it and what tools do I need?

r/Plumbing on Reddit: Slow drip, older Moen double-handle faucet - no set screw. Need help!
April 10, 2025 -

I am trying to address a slow-drip, Moen double-handled faucet. Problem is I cannot figure out how to remove the handle to figure out if it's a cartridge or washer issue. I removed the top cap, but as you can see in the pictures there is no screw inside the stem to remove/loosen. There's also no set screw anywhere on the sides/base (see pics). The bottom ring is part of the base, and not removable. I tried brute-force to lift up/remove but that doesn't seem to do anything other than give me a heart-attack that I may damage the thing.

Any guidance would be appreciated. Trying to avoid spending $$$'s to have a plumber come out to address a simple drip.

Thanks in advance!

Most Moen faucets use either a 1225 (one-handle) or a 1222 (Posi-Temp shower/bath) cartridge. Check your faucetโ€™s manual or the old cartridge itself for stamped markings.

Hi everyone recently I started to notice that my Moen bathroom faucet is leaking under the cabinet right below the faucet (see red arrow here https://imgur.com/a/WBT5AzX). I called the plumber and they said I would need to contact Moen to order the part but the plumber never told me what part so what failed part could possibly be causing that leak? When I contact Moen what should I tell them there where is it leaking from since I cant show them the photo so posting here for help as you guys can see the photo here. Thanks
