Replacement Moen cartridge
Moen is an Ohio company that manufactures various types of kitchen faucet appliances. A major component in nearly all Moen faucets is the Moen 1225 cartridge. This cartridge assists controlling water flow and water temperature. A Moen cartridge may occasionally need to be replaced, especially if the faucet is aged. Rather than calling a plumber to replace the cartridge, learn how to change a Moen cartridge yourself.
Insert the flat-head screwdriver into the top of the Moen faucet between the faucet cover and the edge of the sides of the faucet. Push down to pop off the faucet cover.
