Posi-Temp Pressure Balanced Shower Cartridge

The Moen Posi-Temp 1222 is a pressure balanced shower cartridge engineered for Moen single-handle tub and shower faucets. This solid brass cartridge delivers reliable hot and cold water control while maintaining consistent temperature under varying water pressure conditions. Designed as a direct replacement for existing Posi-Temp valve systems, the 1222 cartridge restores smooth operation and stops leaks caused by worn internal components. The cartridge includes a twisting cap removal tool and installation instructions, making it accessible for both professional plumbers and skilled DIYers tackling shower valve repairs.

• Pressure Balancing Technology: The cartridge automatically compensates for fluctuations in hot or cold water supply pressure, preventing sudden temperature swings that can occur when toilets flush or other fixtures turn on elsewhere in the home.
• Solid Brass Construction: Built from durable brass rather than plastic components, this cartridge resists corrosion and wear over extended service life, reducing the frequency of future replacements.
• Hot/Cold Operation: The cartridge controls both hot and cold water flow through a single handle movement, giving users precise temperature adjustment with smooth, consistent rotation.
• Twisting Cap Removal Tool Included: The included plastic removal tool grips the cartridge's external tabs to aid extraction of the old unit, simplifying what is often the most difficult step in cartridge replacement.
• Direct Moen Replacement Part: This is the genuine Moen cartridge specified for Posi-Temp valve systems, ensuring proper fit and function without the compatibility issues common with aftermarket alternatives.

The Moen 1222 cartridge is designed exclusively for Moen Posi-Temp single-handle tub and shower valves. It replaces the earlier 1222B model cartridge. This cartridge does not fit Moen's single-handle 1225 cartridge system or two-handle faucets requiring the 1224 cartridge. Verify your existing valve uses a Posi-Temp pressure balancing system before ordering. Installation requires removing the faucet handle, trim, and retaining clip to access the valve body.

Installation involves shutting off water supply, removing the handle and escutcheon, extracting the retaining clip, and using the included twisting cap to remove the old cartridge by rotating counterclockwise. Insert the new 1222 cartridge with the brass stem pointing out, ensuring proper alignment before reinstalling the clip, trim, and handle. The cartridge requires no ongoing maintenance once installed. If the valve continues to drip after cartridge replacement, inspect and replace worn seats and springs within the valve body.

A: Moen Posi-Temp single-handle tub and shower valves use the 1222 cartridge. This brass pressure balancing cartridge controls both hot and cold water flow and maintains consistent temperature by compensating for pressure changes in the supply lines. The 1222 replaced the earlier 1222B model and fits Posi-Temp valve bodies installed in residential and commercial applications.

A: The Moen 1222 is a pressure balanced cartridge for Posi-Temp tub and shower valves, while the 1225 is a different cartridge design for Moen single-handle faucets. The 1222 specifically fits Posi-Temp valve systems and includes hot/cold operation with pressure balancing technology. These cartridges are not interchangeable, each fits distinct Moen valve platforms with different mounting and sealing configurations.
