How do I Replace a Kohler Faucet Cartridge?

Kohler designs faucets for bathrooms and kitchens. These faucets, like other brands, have cartridges inside them that control the flow of hot and cold water. When the parts inside the cartridge wear out, it is important to replace them because leaks can occur. Anyone with basic home improvement knowledge can perform this task. It typically takes between 30 minutes and an hour to complete.

You can repair leaks by replacing faucet cartridges.

Step 1

Close the water valves behind your shower wall (or under the sink in bathroom sink faucets) to prevent spills.

Step 2

Take the cap off the handle cover located in the center of the unit. Use a Phillips head screwdriver to loosen and remove the screw located underneath the cap. Slide the handle off.

Step 3

Pull out the trim collar, which is a cylindrical-shaped piece of metal around the faucet head. Pull off the trim piece by hand.

Step 4

Use a Phillips head screwdriver to unscrew the two screws on the faucet plate, which surrounds the head of the faucet. Pull off the metal faucet flange from the shower wall. Unscrew the two screws beneath the faucet flange. Remove the smaller metal collar underneath.

Step 5

Grasp the cartridge stem and pull the cartridge out. Wiggle the cartridge from side to side to loosen it, if necessary.

Step 6

Insert the new cartridge by sliding it into the faucet. Replace the metal collar, flange and trim pieces. Tighten all the hardware with the screwdriver.

Step 7

Slide the handle back onto the new cartridge stem. Insert the retaining screw and tighten it with the screwdriver. Replace the cap on the faucet.
