1225 Cartridge: Kitchen Faucet


The 1225 is a water flow cartridge built in directly below the faucet handle and controls both volume and temperature. It is commonly used in Moen single handle faucets produced prior to 2009 (date varies based on style and model).


  • The water supply shut off valves must be turned off- see article How to Turn Off the Water Supply to the Faucet.
  • Recommended Tools: Pliers 
  • The following instructions assume the handle and associated handle pieces have been removed. For additional details, visit and select the type you are repairing. The faucet guide will contain specific information on handle assemblies associated with that style of product.

    Moen manufactures many types of faucets that use the 1225 cartridge. The different faucet categories are based on where the on/off handle is located. Refer to the images below based on your handle location.

Removing The Cartridge
1. Slide the copper clip (#3) out of the valve body (#4). Note: The copper clip (#3) is installed between the gaps on the valve body. cartridge clip.png
2. Using the plastic twisting tool (#2), provided in the 1225 cartridge kit, rotate the cartridge (#1) 1/4 of a turn (90 degrees) in either direction to help loosen the cartridge (#1). twisting tool.png
3. Remove the twisting tool (#2) and raise the stem of the cartridge (#1) until it stops. Using pliers, grab the stem of the cartridge (#1) and pull the cartridge (#1) out. This may require some effort. Note: It is highly recommended to clean and flush the valve body (#4) before installing the new cartridge (#1). See article Valve Body Cleaning and Flushing for additional details.
Installing The Cartridge
1. Slide the new cartridge (#1) into the brass valve body (#4) aligning the two clear plastic tabs on the cartridge with the cutouts on the brass valve body (#4). clipboard_eeaf03da8a78fdfa9dbe7e58ef331d76f.png

2. Gently slide the copper clip (#3) back into the brass valve body (#3) on top of the cartridge (#1). If you encounter any resistance, do not force the copper clip (#3), see FAQ's.

3. Rotate the stem of the cartridge (#1) so the small notch is facing forward. The notch on the stem of the cartridge (#1) determines the hot and cold location. If hot and cold are reversed, see article How to Reverse Hot and Cold for a 1225 Cartridge in a Kitchen Faucet. clipboard_ef35b99ba1dfc1774152102ed2eeb0c90.png

Why won't the cartridge clip fit properly in the valve body or around my Moen cartridge?

Use the twisting tool by applying pressure to push the cartridge (#1) completely into the valve body (#4). The plastic tabs on the cartridge (#1) must be flush with the valve body (#4) and the plastic tabs on the cartridge (#1) must be centered on the cut outs on the valve body (#4).

*If the copper clip (#3) cannot be installed for any reason or appears to be damaged or broken, the water cannot be turned back on to the faucet until the copper clip (#3)  is replaced.

Why is the hot and cold water on my Moen Kitchen faucet reversed?

On most faucets when you move the faucet handle to the left, you will get hot water. If you move the faucet handle to the right, you will get cold water. This is a function of the cartridge stem. If the hot and cold are reversed, rotate the stem of the cartridge (#1) 180 degrees.
