Moen1222 One-Handle Posi-Temp Faucet Cartridge Replacement for Moen Tub Shower and Shower Only Configurations, Brass and Plastic

I wasn't sure if this was the right cartridge for my old 2000's shower faucet- but it was!!! Handle just turns clockwise from cold to hot! Our spout was dripping a ton of water so I figured this was the problem. Thankfully it fixed leaky spout! Directions for DIY ladies....Step 1- turn your water main offStep 2- take of handle with Allen wrench- it's a weird size like 7/64 or something/and yes it sucked!Step 3- unscrew that Phillips head and black piece. Take out metal pipe thing( slides out) & take out above pin with needle nose pliersStep 4- good luck getting out a very old cartridge! Ours was super stuck - prob 20 yrs . See PICS of my husband carefully wedging it out with a screwdriver and a pair of grips! Our stem actually broke off but we did get it out!It was like a huge gush of black water and grossness and the seals were completely off broken inside the pipe . Make sure you look inside and get all broken pieces of rubber out!*Step4 - lube up your new cartridge and put in. I thought mine was in and couldn't put my clip back in! You have to reallly push it in to get on back in.* make sure the notch on metal is on top before you put everything back together!Success. Not hard just watch some videos!It stopped my leaky spout and I didn't have to pay a plumber or arm and a leg! Amazon saves the day again!

First of all, I should have changed the old one at the first signs of it going bad. The white lime deposits or whatever you want to call it is what causes the problem. You will notice the black side rubber pieces, when you try to remove the old cartridge, they can get stuck in the internal slots inside as you're pulling it out. Once that happens you're going to have a very hard time getting it out. In the long run my old one snapped in half. I had to break it out in small pieces being careful not to scar up the inside of the housing.All that said, I didn't have a cartridge puller. They sell an all brass 1222 replacement cartridge claiming it will last longer. First of all the plastic housing of my old cartridge didn't fail. Those rubber inserts started to catch in the internal slots. It actually stopped turning when I tried to get out of the shower leaving me standing ice water to get it stopped. Since my old cartridge was plastic I was eventually able to break it apart. If it was the brass cartridge it would still be in there with the rubber pieces folded over making it impossible to remove. There is not enough clearance for it to come out if the rubber gets doubled over. Even with a puller. The brass cartridge sounds like a great idea. But not if it gets really stuck like mine did. You can not break it into little pieces to remove it. You'll have to buy an entire new cartridge housing. About $100Now if I wanted to use the brass cartridge you would have to change it at the very first sign of trouble. I don't know if they sell just the black side rubber pieces so you could change them. But if they don't you're going to have to buy a cheap plastic cartridge just to get them. So what did you save?I will just keep on using the plastic cartridges. Keeping an eye out for the first signs of failure. My new plastic one works as smooth as hot butter. I'll be buying a cartridge puller. And a spare plastic cartridge. I won't be waiting until I can't turn it off to swap it out. I should have changed it a year or two ago. Especially now that I see how it works and how it can fail. Plus it's a pretty easy fix. If you don't have to destroy the old cartridge to remove it.One more thing as mentioned in another review, buy some silicon lube and coat it real good when you install it. And maybe as a preventive measure, pull it out once in a while and lube it up again. 3 Phillips screws, one Allen screw and the retainer clip. Pull it out check the condition of the rubber side pieces and smear it up, and put it back in. Very simple job if you do it before it turns into a nightmare.

Our shower had a constant drip and saw to replace the cartridge. We went to local hardware store and picked one up, replaced old one and it ended up worse than before, after research this is a common problem. Ordered this one, actual moen brand and shower doesn’t drip anymore and the second time of installation was way easier than the first round! Moral of story and excessive research, order 2, of the first one works, great, return the second one or keep it for next time, but don’t be surprised if the first cartridge doesn’t work.

Fixed the valve from jamming up and only rotation one way.I highly recommend polishing the brass inside of the valve for even better performance.I used a drill mounted cone-shaped foam polisher (for poshishing car wheels) with metal polishing compound, and it both cleaned the rubber and hard water off of the brass, it polished the bass to a mirror shine. This allowed the valve to be inserted with ease and it also rotates smoother than a brand new valve now, might even extend the life.Note, my valve housing was so jammed up, I had to break the core up, piece by piece... If I would have known that the mfr. Made a puller tool for these, I would 100% have ordered it to make my life easier

Needed the cartridge removal tool Otherwise could not remove and use this
