Things You'll Need:
- Screwdriver or Allen wrench
- Adjustable pliers
- Needle nose pliers
- Heatproof grease

Step 1
Turn off the sink's water supply underneath the sink. Two hoses connect to the sink's faucet assembly--hot and cold. Twist the valve in the center of each water supply line in a clockwise direction to turn the water off.

Step 2
Disassemble the faucet's handle assembly to access the diverter valve. To remove the handle, turn the single set screw located either on top of the handle or on the side of the handle in a counterclockwise direction. You'll need either a screwdriver or an Allen wrench, depending on the design. Pull the handle off the faucet's body. Grasp the cone-shaped cap with a pair of adjustable pliers, and then twist the cap to remove it. Finally, slide the faucet's spout off the body to reveal the diverter valve. Grasp the diverter valve with the needle nose pliers and pull the valve out of the faucet body. Remove the diverter valve from its water supply hose by pulling the hose away from the valve.

Step 3
Coat the rubber tip of the replacement diverter valve with heatproof grease and slide the valve's water supply hose onto the back of the diverter valve. Insert the diverter valve into place in the faucet body, then slide the faucet's spout over the divert valve, followed by the cone-shaped cap. Tighten the cap with the adjustable pliers. Install the faucet's handle by positioning the handle over the cone-shaped cap and securing the handle in place with the handle's set screw. Turn on the water supply valves underneath the sink to complete the installation.
