How to Repair a Kohler Bathroom Faucet When You Can't Remove the Handle

Unscrew the aerator from the faucet, which is the metal round piece at the end of the faucet where the water comes out. It helps control the water stream and it often gets clogged with mineral deposits over time. In some cases, you will need a wrench to loosen the aerator before twisting it off, especially if the buildup is severe.

Rinse off the aerator with a different faucet. Don't use the same sink because water splatters in various directions without an aerator in place. Drop the piece into a glass of white vinegar overnight to help break up deposits and clean the screen in the aerator. This is often enough to repair water flow issues. Reattach the aerator after cleaning it.

Scrub at the faucet fixtures with a scrubbing cloth to help remove any rust or corrosion that impedes function. Spray the faucet with vinegar or a mineral remover and wipe at the metal until buildup is removed.

Turn off the water in the house to prevent leaking while disassembling the faucet. Shut off the valves going directly to the faucet and then run the faucet briefly to clear out the water supply lines.

Disconnect the hoses from the faucet fixture under the sink. Untwist the T connector and then undo the bolt under the sink that holds the faucet in place with a wrench.

Pull out the faucet fixture. If it is caulked around its base, remove the caulking carefully with a razor.

Replace the connectors and washers on the faucet fixture to get fresher, tighter-fitting models that help prevent leaking. Tighten any loose pieces on the faucet if possible.

Reinstall the faucet and reconnect the hoses. Caulk around the base of the faucet where it meets the sink to help protect against leaks and to further secure the faucet.
