Kohler faucets are built to last longer. However, rubber o rings and moving parts can wear out after extended use. If you notice a leak coming below the faucet handle when you move your spout from side to side, then the internal spout barrel o rings are damaged and need to be replaced.
Other problems you may experience with your kitchen faucet are the sporadic disruption of water flow when turning on the faucet and low water flow from the handheld sprayer. Fortunately, you can deal with all of these problems by taking the faucet apart and doing the repairs yourself. Read on to understand how to remove a single stem Kohler kitchen faucet.

Turn Off the Water
Kohler is one of the best kitchen faucets with a sprayer available on the market. So, if you want to remove it, start by turning off hot and cold water supplies. Hot and cold shut off valves should be located under your sink. Turn them both to the right, and then try turning on the faucet to confirm that no water is coming out.
Place a small bowl or pan under the faucet to catch any water that may drip when you disconnect the supply lines.
Use the adjustable wrench to loosen and remove the flexible supply lines from the shut off valves. You may need to use needle nose pliers to hold on to the nut while you loosen the bolt.
Access the Cartridge
Depending on the problem, you may not need to remove your Kohler kitchen faucet. If your Kohler kitchen faucet is leaking from the spout or out of the handle, or the handles are too tight or too loose, then remove the handle to access the cartridge. Replacing the cartridge will fix leaks and mobility issues.
Look behind the handle for a small oval. Flip a flathead screwdriver under this oval tab to pop it off and reveal the bonnet nut. Use an Allen wrench to remove that nut and the handle. Twist the neck counterclockwise to remove it from the handle.
Use an adjustable wrench to remove the kitchen faucet nut holding the cartridge down. That way, you'll see the cartridge. You can pull it by hand, or you may need needle nose pliers to help remove it. Now that the old cartridge is out, inspect it for any wear or damage. If there is any damage, you'll need to replace the o rings as well.
Remove the Aerator
Most kitchen faucets have an aerator that screws onto the end of the faucet. The aerator is what adds air to the water stream and controls the flow rate. You'll need to remove this in order to get to the screen below. Use a pair of pliers and unscrew it counterclockwise.
If it seems stuck, wrap a towel around the end before using an adjustable wrench to twist it off. On your pull-down faucet, the aerator is surrounded by the spray face. Line up an adjustable wrench with straight lines on the aerator and firmly pull it out.
Remove the Kohler Kitchen Faucet
Here are the instructions on how you can remove a single stem Kohler kitchen faucet.
Disconnect the Supply Lines
The first thing you need to do is to disconnect the supply lines. You can do this by shutting off the water valves that are located under the sink. Once the water is shut off, open the faucet to release any remaining water in the lines and use a towel to soak up any water that may drip out.
Next, use an adjustable to unscrew the lines from the faucet. Once the lines are disconnected, you can now remove the faucet.
Remove Faucet Plug Button
Locate the faucet plug button, which is located on the top of the faucet. Use a flathead screwdriver to pry off the button.
Remove Faucet Handle and Bonnet Nut
Use an Allen wrench to remove the set screw that is located on the underside of the faucet handle. Once the set screw is removed, you can pull off the faucet handle.
There will be a bonnet nut located on top of the faucet body. Use a wrench to loosen and remove the nut. If there is any mineral buildup, use a solution of vinegar and warm water to dissolve the deposits.
Remove Faucet Hub Assembly
There will be a washer and a rubber o ring located on the faucet body. Remove these with your fingers. Remove the hub assembly by pulling it away from the faucet body. After years of operation, mineral deposits may prevent the hub assembly from coming off easily. In this case, use a pair of pliers to grip the hub and pull it away from the faucet body.
If it doesn't move, you may need to position a wide blade screwdriver between the sink and the assembly. Gently pry up until the assembly comes loose.
Replace Faucet Diverter
Over time, the diverter will become worn and will need to be replaced. The diverter is a small valve located on the back of the faucet body. To remove it, use a pair of needle-nose pliers to pull it out. Push the new diverter, fins pointing out into place with your fingers. Also, remember that a clogged diverter can also bring problems, especially if it’s a pull-out kitchen sink sprayer.
Lubricate the O Rings and Faucet Body
Once the diverter is replaced, apply a small amount of plumber's grease to all of the O rings. This will help to keep them from drying out and cracking. Reassemble the faucet in the reverse order that you took it apart.
Replace Kohler Faucet Control Cartridge
If your faucet is leaking from the handle, you will need to replace the control cartridge. The cartridge is located under the handle. To remove it, use a hex wrench to loosen the set screw. Pull the cartridge out and take it to a hardware store to find an exact replacement. Install the new cartridge by pushing it into place and tightening the set screw.
Smear Some Lubricants on the Bonnet Threads
If your faucet is leaking from the spout, chances are it is because the bonnet nut is not tight enough. To fix this, remove the handle and use a hex wrench to loosen the bonnet nut. Once it is loose, smear some plumber's grease or petroleum jelly on the threads. This will help to create a seal and prevent the nut from coming loose in the future.
