Installing New Valves (GP77005-RP and GP77006-RP) In A Two Handle 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 new valves in a two handle faucet is something almost anyone can do!
First turn off the water to your faucet and remove the handle. On most two handled faucets, this can be done by unscrewing the bonnet under the lever. On knob style faucets, there should be a plug button over a screw to remove the handle.
Once the handle is removed you will be able to see the top of the valve. Some faucets will have an adaptor over the stem of the valve. You will want to remove this, and save it to use once the new valve is installed.
Using an adjustable or fixed wrench, or even a 5/8 inch deep socket wrench, loosen the valve by turning it counterclockwise.
Once the valve is out, install the new valve by screwing it back into the faucet, moving clockwise. Tighten the valve to 1/8 to 1/4 turn past hand tight with your wrench. Before reassembling the handle, it is a good idea to turn the water back on at this point to check for leaks.
Once you have made sure there are no leaks, simply reassemble the remaining parts.
