Replacement Shower Cartridge Kit Compatible with 1222-1222B Posi-Temp Shower Bodies - with Retaining Clip, Installation Instructions, Lubrication

it is not truly 100% compatible to Moen 1222

Turn off the main water supply. Open a sink valve on the lowest floor of the house to drain the water from the pipes. Turn on the shower to drain the remaining water from the shower pipe. Remove the shower handle, cover and remaining parts. Remove the retaining clip holding the cartridge in the valve body. Don’t use this tool to twist the cartridge as I have seen many instructions tell you to do. There are plastic tabs on the cartridge that prevent rotation. First rotate the cartridge stem so that the chamfered edge is down. Back off the phillips head screw on the tool most of the way out. Back off the nut on the tool most of the way back towards the T handle. Place the tool in the left and right slots of the valve body which is holding the cartridge. Fully tighten the phillips head screw on the tool being careful not to rotate the the cartridge stem and keeping the tool in the left and right slots. Tighten the nut with a wrench or pliers to pull the cartridge out of the valve body. The nut is large so you will need a large wrench or adjustable plumbers pliers. Install new cartridge and reinstall remaining hardware. Turn the water valves off on the sink that you opened earlier. Turn the water main back on. There will be air in the lines until you run the water a few seconds. Done.

The media could not be loaded.  Only lasted 1 year and 2 months then back to dripping

I'm a general DIYer with little to no plumbing experience. One of our tubs was suffering from extremely low output. I've done the general DIYs I've come across online, none of which fixed the problem. As a desperate last attempt to fix our tub, I decided to give this part a go. I also bought a cartridge removal tool in hopes of making my life easier. Installation was pretty simple and I followed Moen's own video tutorial for removal and replacement. Water started flowing normally again installing the replacement. The I did not use the clip that came with this because it didn't seem to hold in place, I ended up using the old clip from my previous cartridge. Overall I'm happy with the value of this and am happy to have a working tub again... I'll probably disassemble the other one so that I can get a good understanding of where it failed and to see if I can "fix" it for when this one might fail, and I can just swap between the two until one is beyond repair.Overall, I appreciate the value that this part brings, since it's almost half the price of the OEM part. I'll be happy as long as it continues to work and has decent longevity. I'll update this should the part fail within a short time frame. However, at the moment I am very happy with this purchase and would purchase again if necessary *knock on wood*

This is my second purchase of this item from this company. No issues on the first order. This time the valve leaked worse than the one I was replacing! Will have to find another place to order

The part was exactly what I needed to stop my leak and is very easy to install.

You must have a pulling tool in-able to remove the old one, use plenty of plumbers grease to slide the new one in, what is supplied is not enough. Hold the gaskets in place as you slide the new one in other wise they will slide out of place thus not letting the new one slide all the way in. Make sure the retainer clip slides back in with ease, do not force. also be sure to clean the houseing of any build-up .take note on the position of the old one and make sure the new one is put in the same otherwise the hot and cold will be reversed. There several of the moen cartridges, make sure you have the rite one before you remove the old one, alot of the time there are no shut off valves to isolate the tub. I have changed many of these over the years, most of the result of the week-end-warrior trying to save money or impress his girl friend.

I bought it in Jan 2021, now it starts to leak and drop again. DON'T WASTE YOUR MONEY!
