How do you remove a stuck moen 1224 cartridge? My shower is a two handled moen chateau installed in 1994. Getting the collar of the cartridge was no problem. However, the cartridge won't budge. I don't have a puller but have tried needle-nose vice grips, wd 40 and channel locks with no luck. Thanks
The manual for the Moen 1224 cartridge seems to suggest that it just pulls out. Instead of WD-40 try something like CLR. I'd expect you have something like lime or hard water making it stick more than rust. WD-40 won't do much on lime or hard water type corrosion and its not great on rust either.
Are you sure you have a Moen Chateau? It seems that the current line up is a single handle shower fixture. Can you provide a link to the manual or a model number for the Chateau in your shower?
On my bathroom sink I disconnected the water supply lines to the faucet and stuck a 5/16 rod into the water supply holes until they contacted the backside of the cartridges. Then I gently tapped them out. Worked great. Much easier to push out than pull out. A basic law of physics from an aerospace engineer.
