Faucet Repair

Find the hot and cold water shut-off valves, usually located beneath the sink basin. Turn these valves clockwise until they are firmly closed. After closing the valves, open the faucet handles to release any residual water pressure and confirm that the water supply has been successfully shut off.

Examine the faucet for any brand names or model numbers. If not visible, take clear photos of the faucet and its components, especially around the handle and spout base. You may need to consult the manufacturer's website or a plumbing supply store with this information to identify the specific cartridge required for your faucet model.

Pry off any decorative cap on the faucet handle, usually located at the front or top. Look for a small set screw, often hidden beneath this cap. Use an Allen wrench or screwdriver to loosen and remove the set screw. Once the set screw is removed, carefully pull the faucet handle straight up and off the faucet stem.

With the handle removed, you will see a retaining nut or clip securing the cartridge. Use an adjustable wrench to counter-clockwise unscrew the retaining nut. If a clip is present, use needle-nose pliers or a screwdriver to carefully pry it out. Be gentle to avoid damaging the faucet body.

Once the retaining nut or clip is removed, the cartridge should be accessible. You may be able to pull it straight out with your fingers or needle-nose pliers. Some cartridges might be seated tightly and require a slight twist or wiggling motion. Some manufacturers provide a cartridge puller tool for stubborn cartridges.

Inspect the area where the cartridge was seated for any mineral deposits, debris, or old sealant. Use a soft cloth, an old toothbrush, or a small brush to clean the interior of the faucet body thoroughly. Ensure the seating surfaces are smooth and free of obstructions for the new cartridge.

Align the new cartridge with the opening in the faucet body, paying attention to any notches or slots that ensure correct orientation. Gently push the cartridge into place until it is fully seated. Some cartridges may require a slight turn to lock into position.

Once the new cartridge is in place, reinstall the retaining nut or clip. If it's a nut, tighten it with the adjustable wrench until snug, but do not overtighten. If it's a clip, ensure it snaps firmly into its designated groove.

Slide the faucet handle back onto the stem, ensuring it is properly aligned. Reinsert and tighten the set screw using the appropriate Allen wrench or screwdriver. Replace the decorative cap if one was removed.

Slowly turn the hot and cold water shut-off valves counter-clockwise to restore the water supply. Check all connections and the faucet base for any signs of leaks. Turn on the faucet and test both hot and cold water flow, ensuring there are no drips from the spout when the faucet is turned off.
