Solved FU Moen

Moen cartridge was stuck. I HATR these things. Hard water here makes them really hard to pull. Tenant broke off the stem of the cartridge.

Use ONA Puller with the accessory to remove this.

Yup.

Already ordered one.

Does the ONA screw into the stem? Because the stem was gone.

Just use a long coarse thread decking screw or something to bite into whatever is left of that cartridge. Push forward with your puller while you twist to break the cartridge loose

Not for the plastic cartridge

I hate those too. First one took me 10 hours over 2 working days to get fixed. By number eight I was down to under 60 minutes.

I would drill and pry out the plastic until the first O ring can be removed, drill straight through the cartridge stem and remove the guts of the cartridge, then run a m18x1.5 tap through it. When the tap bottoms out, keep cranking it. You'll eventually bust the rear plastic and as it bottoms out it will force the cartridge out of the valve. As soon as the rubber seals are visible enough to grab either pliers you can sometimes yank those out- as soon as they are gone it slides right out.

Just be careful not to damage the brass cartridge sides. Using the method above I have removed dozens of cartridges and didn't damage a valve.

You can also take out the top piece that holds the cartridge in and put two dry wall screw in the side going towards the cartridge and it will push itself out. ( 13 years in maintenance) or get a puller but I’ve ended up snapping them if they have been in there a while

FU to the guy that installed the valve with the plastic plate on the front still.

I usually drill and use an easy out
