Common Causes of Leaks

Before attempting any repairs, it's essential to identify the source of the leak. Common causes include:

Worn or damaged O-rings
Loose or faulty cartridge
Corroded or cracked hoses
Defective aerator or spout

Tools and Materials

To fix a Kohler single handle bathroom faucet, you will typically need the following tools and materials:

Hex key or Allen wrench
Phillips screwdriver
Replacement parts (as needed)

Step-by-Step Guide to Repair

Follow these steps to repair the leak:

Shut off the water supply: Locate the shut-off valves beneath the sink and turn them off.
Remove the handle: Use the hex key or Allen wrench to loosen the set screw on the handle. Then, gently pull the handle straight up to remove it.
Remove the cartridge: Use an adjustable wrench to unscrew the cartridge retainer nut. Pull the cartridge straight up to remove it.
Inspect and replace the cartridge: Examine the cartridge for any damage or wear. If damaged, replace it with a new cartridge of the same size and type.
Inspect and replace O-rings: Remove the old O-rings from the cartridge and faucet body. Clean the surfaces where the O-rings sit and apply a thin layer of silicone grease to the new O-rings. Install the new O-rings.
Reassemble the faucet: Insert the cartridge back into the faucet body and tighten the retainer nut. Reattach the handle and tighten the set screw.
Turn on the water supply: Slowly turn on the shut-off valves and check for leaks. If there are no leaks, the repair is successful.

Additional Tips

If the leak is coming from a cracked hose, remove the hose and replace it with a new one.
If the leak is coming from the aerator or spout, unscrew and remove the aerator or spout and clean or replace it.
If the leak persists after following the above steps, it may be necessary to contact a licensed plumber.
