Gather Necessary Tools and Materials

Before starting the replacement process, ensure you have all the necessary tools and materials:

Replacement Kohler faucet valve (check the specific model of your faucet)
Adjustable wrench or basin wrench
Phillips screwdriver
Flathead screwdriver
Plumber's putty
Rags or towels

Step 1: Turn Off Water Supply and Drain Faucet

Locate the water supply valves under the sink and turn them off to stop the water flow. Open the faucet to drain any remaining water from the pipes and faucet.

Step 2: Remove Handle and Escutcheon Plate

Use a Phillips screwdriver to remove the screws holding the handle in place. Carefully pull off the handle, being mindful not to damage any components. Next, use a flathead screwdriver to pry loose the escutcheon plate surrounding the faucet base.

Step 3: Unscrew Packing Nut and Remove Valve Cartridge

Using an adjustable wrench or basin wrench, cautiously loosen and remove the packing nut located at the base of the faucet. Then, use a flathead screwdriver to gently pry out the valve cartridge. Note the position of the cartridge for proper reassembly.

Step 4: Clean and Apply Plumber's Putty

Clean the faucet body and cartridge seat of any old sealant or debris. Apply a thin layer of plumber's putty around the base of the new valve cartridge.

Step 5: Insert New Valve Cartridge

Carefully align and insert the new valve cartridge into the faucet body. Ensure it's properly seated and aligned with the water supply lines.

Step 6: Tighten Packing Nut

Hand-tighten the packing nut onto the faucet body. Then, use an adjustable wrench to further tighten the nut, but avoid overtightening.

Step 7: Replace Escutcheon Plate and Handle

Position the escutcheon plate around the faucet base and secure it with screws. Finally, reattach the handle and tighten the screws.

Step 8: Turn On Water Supply and Check for Leaks

Slowly turn on the water supply valves and check for any leaks. Observe the faucet for proper operation and adjust the handle as needed to ensure smooth water flow.
