Step-by-Step Kohler Bathroom Faucet Cartridge Removal

This guide will provide a detailed walkthrough of the process for removing a Kohler bathroom faucet cartridge. By following these steps, you can effectively replace a worn-out cartridge and restore your faucet’s functionality.

Turning Off the Water Supply

Before starting the cartridge removal process, it’s crucial to shut off the water supply to the faucet. This prevents any water from leaking during the process and potential damage to your bathroom.

Locate the water supply valve for the faucet. It’s usually found beneath the sink or behind the wall.
Turn the valve clockwise until it stops. This will shut off the water flow to the faucet.
To confirm that the water supply is off, turn on the faucet handle. If no water comes out, the water supply is successfully shut off.

Draining the Faucet

After shutting off the water supply, it’s important to drain any remaining water from the faucet. This step helps prevent water from dripping during the cartridge removal process and ensures a clean and dry working area.

Open the faucet handle to release any remaining water in the faucet.
Use a towel or sponge to absorb any dripping water to prevent water damage to the surrounding area.

Removing the Handle and Escutcheon

To access the cartridge, you’ll need to remove the faucet handle and escutcheon. These components cover the cartridge and its access points.

Identify the handle screw or set screw on the faucet handle. It may be hidden under a decorative cap or located on the side of the handle.
Use a small screwdriver to loosen and remove the handle screw or set screw. Once removed, gently lift the handle off the faucet stem.
Locate the escutcheon, which is the decorative plate covering the faucet base. It’s usually held in place by one or more screws.
Use a screwdriver to remove the escutcheon screws and gently pull the escutcheon away from the faucet base.

Removing the Cartridge Retaining Nut

The cartridge is held in place by a retaining nut. Removing this nut allows you to access the cartridge and pull it out.

Locate the cartridge retaining nut. It’s usually located beneath the faucet stem, visible after removing the handle and escutcheon.
Use a wrench or adjustable pliers to hold the faucet stem steady while you loosen the retaining nut.
Turn the retaining nut counterclockwise to loosen it. It may require some force, but be careful not to damage the faucet stem.
Once the retaining nut is loose, carefully remove it from the faucet stem.

Removing the Cartridge

With the retaining nut removed, the cartridge can be pulled out of the faucet stem.

Gently pull the cartridge straight up and out of the faucet stem. It may require some effort, but avoid forcing it.
Inspect the cartridge for any signs of wear or damage. This will help determine if the cartridge needs to be replaced.
