When you are replacing the faucet cartridges on your Moen faucet, you will need to remove the handles. Most Moen shower faucet handles use a single screw hidden behind a decorative cap in the center of the handle to secure the handle to the faucet stem. Some handles however, will require that you twist the handle sleeve to unlock the handle from the faucet assembly. If your shower faucet has separate controls for flow and temperature, you will need to unlock the handles.
Temperature Faucet Handle and Flow Faucet Handle
Turn off the water supply to the shower. The shut-off valves are behind the shower wall. The access to the shut-off valves is usually in an adjacent room or closet. If you cannot find the shut-off valves, turn off the main water supply to the house.
Remove the decorative cap in the center of the Moen temperature faucet handle. Carefully pry the cap out of the faucet handle with a small flat head screwdriver.
Remove the screw that secures the handle to the faucet stem with a flat head screwdriver. The screw is in the center of the handle. Turn the screw counterclockwise to remove the screw.
Grab the lever of the handle with one hand and rotate the handle sleeve counterclockwise with your other hand. This will unlock the handle from the wall. Pull the handle straight off the faucet stem.
Grasp the flow faucet ring with your fingers and grab the faucet sleeve with your free hand. The ring is the decorative ring between the wall and the faucet sleeve.
Turn the faucet sleeve counterclockwise to unlock the faucet handle. Pull the faucet handle away from the wall.
