How can I remove these to replace the cartridges? the one on the left has no screw for the handle, it comes right off when I remove the cap. the other one seems to have a headless screen inside there and no way that I can see to remove it. Does the whole handle unscrew to access the cartridge? On Moen's site none of the handle types seem to match. I am assuming it's Moen because everything else in the house is.

A shower that hasn’t been used in about a year is no longer producing cold water (and the pressure seems lacking when the faucet is set to cold). Other showers in the house have no issues.

It’s a single handle faucet by Moen. I was able to remove the handle, but the escutcheon seems to be sealed to wall? My assumption is this piece is necessary to replace the cartridge (which I’m hoping is the culprit).

Any sense of what cartridge this might be? Do I absolutely need to remove the escutcheon?

Thank you for any assistance and guidance!

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.

I'm replacing an ancient Moen shower cartridge at my girlfriend's house and I'm stuck. I got the old one out surprisingly easily and the new one (#1225) slid right in. However, I can't manage to get the flat brass locking pin (kind with two legs) to slide in to lock the cartridge in place. It feels like I'm getting solid resistance on both sides despite having lined the notches up as carefully as possible and making sure the new cartridge is seated all the way in. It almost feels as if the new cartridge is a mm or so longer than the old one.

I'm considering using a file or hacksaw blade to widen the slot for the locking pin a little. Any other ideas?

My shower won't turn off and the handle feels a bit stiff (doesn't turn smoothly - but I have it turned all the way to right and the water is still flowing). The cartridge says Moen but that's all I know about it.

I feel comfortable with tools but have no plumbing experience.

I shut off the water to the bathroom for now so it's not a major emergency,

Is replacing the cart something I can do on my own, or am I asking for trouble?

I turned the water off (!), removed the handle, sheath, etc. I managed to get the cartridge clip (?) out from the top.

I’m now trying to pull the cartridge straight out, but I can’t get it to budge.

The whole system of pipes is moving, and I feel like I’m going to create a catastrophic problem if I keep pulling.

Am I missing something that needs to be done first? Am I just weak? 🥺

Thanks in advance!
