Step-by-Step Instructions

Follow these step-by-step instructions to replace the cartridge in your Moen bathroom faucet:

Turn off the water supply to the faucet. There will be two shut-off valves under the sink, one for hot water and one for cold water. Turn both valves clockwise to turn off the water.
Open the faucet to release any remaining water from the lines.
Remove the aerator from the end of the faucet. The aerator is the small, round piece that screws onto the end of the faucet. Use a pair of pliers to unscrew the aerator.
Use a Phillips screwdriver to remove the handle from the faucet. There will be a small screw on the back of the handle. Remove the screw and pull the handle straight up to remove it.
Use an adjustable wrench to loosen the packing nut. The packing nut is the large, round nut that is located behind the handle. Turn the packing nut counterclockwise to loosen it.
Pull the cartridge straight out of the faucet body. The cartridge is a cylindrical-shaped piece that is made of metal or plastic.
Inspect the cartridge for any damage. If the cartridge is damaged, it will need to be replaced.
Insert the new cartridge into the faucet body. Make sure that the cartridge is properly aligned and seated in the body.
Tighten the packing nut by hand. Use an adjustable wrench to further tighten the packing nut, but do not overtighten it.
Reinstall the handle onto the faucet. Tighten the screw on the back of the handle to secure it.
Reinstall the aerator onto the end of the faucet.
Turn on the water supply to the faucet. Check for any leaks.
