Replacing A Valve In A Single Control Faucet
Although Kohler faucets are made with the highest quality, like anything else with moving parts, they may need service from time to time. Kohler faucets are designed for the homeowner to repair. Installing a new valve in a single control faucet is something almost anyone can do!
First turn off the water to your faucet and remove the plug button from the handle. There will be a small screw underneath the plug button.
Loosen the screw to remove the handle. The bonnet will be the next part, looking like a dome with the top cut off. Unscrew the bonnet; it should remove easily by hand, going counterclockwise to expose the valve and mounting nut.

With a large adjustable wrench, loosen the mounting nut, moving counterclockwise. This will expose the valve.
Remove the existing valve. When putting the new valve in place, it is easy to make sure the valve is being installed correctly. It will only fit into the faucet in one direction. In the valve body (this is the base on which the valve sits) there are two depressions in the metal. There are matching pegs on the bottom of the valve to make sure it is lined up correctly every time.
Once the new valve is in place, reinstall the mounting nut, turning clockwise until the nut is hand tight. Then turn the nut ¼ to ½ turn past what you were able to do with your hands. Before reinstalling the handle it is always a good idea to make sure there are no leaks by turning the water back on.
Once you have checked for leaks, just reinstall the remaining parts!
