Turn off the water supply, turn on both handles, and plug the drain. Look under your sink for one or two small valves. Turn the valves clockwise to shut off the water supply to your sink and prevent water from spurting out while you work. [1] X Research source Turn on the handles so the rest of the water runs out. Insert a plug into the drain or pull up on the stopper behind the faucet.
- Plugging up the sink prevents any screws, parts, or tools from falling down the drain.
- If you can’t turn off the water under the sink, turn off the water main in your home.
- Master Plumber Dave Jones says “You’ll likely find the main water shutoff valve on a basement wall facing the front of your house” or “hidden from view inside a closet or wall access panel near the front of the house.” [2]

Pull the decorative cap off the handle and remove the screw. Most sink faucets have a large or small decorative cover that hides the handle’s screw. Use a small flathead screwdriver or utility knife to pry off the cover on the top or side of the handle. Remove the screw underneath with an Allen wrench or screwdriver. [3] X Research source
- Single-handle cartridge faucet: Pry the cap off the top of the handle, remove the screw, tilt the handle back, and pull it off.
- Double-handle cartridge or compression faucet: Pry off the cap on the top of the handle, remove the screw, and pull off or unscrew the handle.
- Single-handle ceramic-disk faucet: Push the handle back and remove the screw underneath. Pull off the handle.
- Single-handle ball-type faucet: Pry off the small cover on the side of the faucet, unscrew the hex-head screw with a hex-key wrench, and pull off the handle.
- Other two-handled faucets may require you to unscrew the handle before you can pry off the cap. If the leak is coming from under the tap, unscrew the tap from the base. [4] X Research source

Unscrew the nut underneath using an adjustable wrench. Use an adjustable spanner wrench to loosen and remove the nut around the base of the handle. [5] X Research source Jones says if the nut “has a chrome or metallic finish… put electrician tape or a rag around it to protect the finish, then use pliers to remove it.” [6] X Expert Source Dave Jones
Master Plumber, Roto-Rooter Plumbing & Water Cleanup Expert Interview. 29 March 2021.- This nut holds down the cartridge, a metal and plastic piece inside the handle that turns the water on and off and controls the water flow. Some models may not have a nut.
- If the nut won’t come off, apply penetrating oil around the screw and let it soak for 10 minutes before trying again.

Pull out the cartridge and inspect it and the O-ring for damage. The O-ring is a piece of rubber that wraps around the bottom of the cartridge. If the O-ring is worn, Jones says to take it to the hardware store to match it with a new one. If the cartridge is broken, you may have to get “a new replacement cartridge from the faucet’s manufacturer.” [7] X Expert Source Dave Jones
Master Plumber, Roto-Rooter Plumbing & Water Cleanup Expert Interview. 29 March 2021.- Jones recommends shining “a flashlight down into the hole that the cartridge came out of. Inspect for debris and if you see any, remove it with your finger or a needle nose pliers.” [8]

Apply grease to the O-ring and cartridge and put them in the handle. Place the O-ring on the open edge of the cartridge and use your fingers to roll it down to the groove near the middle. Apply waterproof plumber’s grease along the outside of the O ring and on the bottom of the cartridge. Insert the cartridge into the handle hole in the faucet. [10] X Research source
- Compression faucet: Coat the washers at the bottom end of the cartridge and the O-ring with grease. If the disk around the washers is broken, replace that, too. [11] X Research source
- Ceramic disc faucet: Clean the cylinder openings inside the handle with distilled white vinegar and a small scoring pad or sponge, then rinse with water. [12] X Research source

Inspect your sink for leaks regularly. A leaky faucet can waste water and increase your water bills. To check for leaks, examine the outside of the faucet, its gaskets, and the fittings of the pipes under your sinks to make sure there aren’t any surface leaks. [17] X Trustworthy Source United States Environmental Protection Agency Independent U.S. government agency responsible for promoting safe environmental practices Go to source
- When you notice a component is broken or damaged, replace it immediately.

Descale your faucet once a month to avoid mineral buildup. Vinegar can help prevent limescale and other mineral deposits from damaging your faucet’s components. Fill a plastic bag with equal parts water and vinegar, secure it around the faucet head, and let it soak for 30 minutes to an hour. Scrub the rest of the faucet with the vinegar solution and dish soap. [18] X Research source
- Remove the bag and brush the head with a toothbrush or cleaning brush and dish soap. Run the faucet to dislodge anything inside, then rinse and dry the area.

If your faucet handle is leaking, you should be able to fix the issue yourself by replacing its O ring. First, turn off your water supply at the valve under the sink and open the faucet to drain any water from the pipe. When the water’s stopped, remove the faucet handle. Depending on the type you have, you may have to pull it straight up, unscrew it counterclockwise, or pry it off with a flat-head screwdriver. Once you’ve removed the handle, unscrew the nut underneath with a wrench. Under the nut, you should see the rubber O ring, which will probably be worn down. Replace the O ring with a new one, then screw the nut and faucet handle back on. Finally, open the faucet gradually to release any air bubbles until the water flows normally. For more tips, including how to unscrew a stiff nut, read on!
