Pro Tip: What's the difference between the 1222 and the 1222b?
There is no material difference between the 1222 and the 1222b. The only difference is that "b" in the 1222b stands for "bulk." So, when large distributors like The Shower Head Store buy large bulk quantities of this cartridge, the packaging will show "b" for bulk.

Moen 1222 - 1222b Posi Temp Cartridge Review
This is the OEM cartridge for Moen's best selling valve, Posi-Temp. You'll generally need a new cartridge if you are experiencing any of the following:
- Shower is leaking from the Shower Head or Tub Spout when the water is off.
- Shower handle leaks when the water is on.
- High resistance when attempting to rotate the handle.
- Inability to control temperature, often realized by the water temperature jumping from cold to hot, without any warm water in the middle.
Moen's Posi-Temp valve is very simple and only has this self-contained Posi-Temp Cartridge, held in by a small horseshoe clip. Below you'll find more information on how to remove and install a Moen 1222/1222b Posi Temp Cartridge.
How To Know If You Have A Moen Posi Temp Valve
The best way to identify if you have a Moen Posi Temp Valve is to remove the Shower Handle and Escutcheon Plate and inspect the valve. The Moen Posi Temp Cartridge has a distinct look, and would be hard to mistake for another part, especially if you have removed the cartridge already. Be sure to shut off your Main Water Supply before doing any work on the valve.
It is also important to not assume that just because it says Moen on the Shower Plate that it is a Posi Temp Valve. There are several Moen Valves on the market, with distinct parts. You can differentiate between these valves by observing how the water turns on and how the temperature is controlled. Moen's Posi-Temp Valve turns on by simply rotating the handle counter clockwise.
If your shower turns on by pulling out the handle, this IS NOT the cartridge for you and you'll want to refer to the Moen 1225 Cartridge to repair your valve.
(Please note that this cartridge is not compatible with any other valves than Moen Posi-Temp Shower Valves.)
Moen 1222/1222b Posi Temp Cartridge Features
Pressure Balancing: Prevents water from scalding you by using a spool that reduces the hot water flow if the cold water supply is suddenly decreased. This often occurs when appliances run in another part of the house - like flushing the toilet.
