Tools You'll Need:

  • Adjustable wrench

  • Screwdriver (flathead and Phillips)

  • Replacement parts (washer, O-ring, or cartridge)

  • Plumber's grease

  • Towels or rags

  • Bowl (to catch water)

  • Allen wrench (if necessary)


Step 1: Turn Off the Water Supply

Before starting any repairs, turn off the water supply to avoid accidental water flow. Locate the shut-off valves under the sink and turn them clockwise until they stop. Open the faucet to drain any remaining water.


Step 2: Remove the Faucet Handle

Use a screwdriver to remove the screws securing the faucet handle. If the screws are hidden, pry off the decorative cap to expose them. Gently pull the handle off. If it’s stuck, use an Allen wrench or handle puller.


Step 3: Identify the Leak Source

Inspect the internal components for wear or damage. Common culprits include worn-out washers, O-rings, or cartridges.


Step 4: Replace the Faulty Parts

  1. Washers and O-rings:

  • Remove the old washer or O-ring.

  • Take it to a hardware store to find an exact replacement.

  • Coat the new washer or O-ring with plumber's grease and install it.

  1. Cartridge:

  • Pull out the cartridge using pliers.

  • Replace it with an identical one from the store.


Step 5: Reassemble the Faucet

Put the faucet handle back in place and secure it with screws. Reattach the decorative cap if necessary. Turn on the water supply and test the faucet. If the leak persists, check if the parts are correctly installed or consult a plumber.


Types of Faucets

Different faucets require specific approaches:

  1. Compression Faucets:

  • Two handles, one for hot and one for cold.

  • Replace washers and O-rings to stop leaks.

  1. Ball Faucets:

  • Single handle with a ball joint.

  • Replace springs, valve seats, and O-rings using a repair kit.

  1. Cartridge Faucets:

  • Single or double handles with a movable stem cartridge.

  • Replace the entire cartridge if it’s faulty.

  1. Ceramic Disk Faucets:

  • Single handle with ceramic disks controlling water flow.

  • Replace seals or the entire disk if damaged.


Preventing Future Leaks

  • Regularly inspect and maintain your faucets.

  • Clean the aerators to avoid clogs.

  • Avoid excessive force when turning handles.

  • Monitor and adjust water pressure to prevent strain on your plumbing system.
