1222 Moen Replacement Cartridge – Aftermarket Shower Cartridge Replacement Compatible with One-Handle Posi-Temp Faucets & Moen Tub Shower | Durable Brass and Plastic | Essential Values

Brand new Moen shower valve had a faulty cartridge. Bought this one to replace it with and it worked perfectly and at half the price. Easy to install with the tool, which is sold separately but is worth it.

No me gustó que se me descompuso la llave del baño pero si me gusto que encontré por línea la refracción igual y a buen precio y la entega fue antes de lo señalado.

Replaced two of these in my home. Used an oem cartridge in the first, and ordered this one to have as a spare/backup. I decided to replace the cartridge in my spare bathroom, and figured I’d give this one a try. The old cartridge was extremely stubborn to remove, and broke apart during removal. The rubber seals had fused themselves to the valve body. I had to essentially pry and break the remnants out of the body. The body was corroded, and I was concerned with getting a good seal from the new cartridge, so I also purchased a 1” ball hone on Amazon. I’m glad I did. The hone allowed me to thoroughly clean up the inside of the valve, and gave me a nice smooth surface for the seals to mate to. The cartridge works great, and after a few months of daily use, is still leak free, and very easy to turn. I won’t hesitate to purchase these for my third bathroom, when the need arises.

Short version: Do not buy this, buy the actual name brand as my water hammer issue as described below was resolved after I installed the Moen brand. Long version: I bought this just as everyone else trying to save $35-40 but it wasn’t worth it. I bought this because we were having water drip from the shower head. I installed this product last October 2024 and ever since we would hear the water pipes hammer after turning off other faucets in the house or flushing toilets. Today (10/19/2025, yes a whole year later) I was determined to fix it thinking it was an unsecured pipe rattling. I opened up the dry wall to see the pipes were still secure and not moving at all when water would shut off. Dejected after not understanding what was going on and thinking I needed a professional plumber, I restarted research online. I saw a couple articles about this on other plumbing forums and then started reading the 1 star reviews on this product, to which I found others had this same exact problem. I went out and bought the $53 Moen 1222 cartridge from Home Depot and installed. WATER HAMMER IS GONE! To my wife and I’s delight we again have silent pipes.

Product seems well made, fit and works perfectly for a Moen shower. Unfortunately, the valve loosener nut is a piece of junk and snapped with only a modest amount of pressure. Also, they literally give you a pill capsule of grease which is an incredibly cheap. Come on guys, you can do better. On a related note, highly recommend purchasing a valve cartridge puller tool, wouldn't have gotten mine out without it as it was seized up good from hard water.
