Introduction
A leaky faucet is one of the most common plumbing problems in any home. Not only is the dripping sound annoying, but it can also waste hundreds of gallons of water per year. The good news? Fixing it yourself is easier than you think!
What You'll Need
- Adjustable wrench
- Screwdrivers (flathead and Phillips)
- Replacement washers or cartridge
- Plumber's tape (Teflon tape)
- Replacement O-rings
- Pliers
- Bucket or towel
Step 1: Turn Off the Water Supply
Locate the shut-off valves under the sink and turn them clockwise to stop the water flow. Turn on the faucet to release any remaining water pressure.
Step 2: Remove the Faucet Handle
Remove the decorative cap on top of the handle to reveal the screw underneath. Unscrew it and carefully pull off the handle.
Step 3: Inspect the Cartridge or Washer
Depending on your faucet type, you'll find either a cartridge or a rubber washer. Inspect it for wear and tear — this is usually the cause of the leak. Replace it with a matching part from your local hardware store.
Step 4: Replace O-rings and Seals
While you have the faucet apart, replace any worn O-rings and seals. Apply plumber's grease to the new O-rings before installing them for a better seal.
Step 5: Wrap Threads with Plumber's Tape
Wrap the threaded parts with Teflon tape (plumber's tape) to ensure a watertight seal when reassembling.
Step 6: Reassemble and Test
Put the faucet back together in reverse order. Turn the water supply back on slowly and check for leaks. If the dripping has stopped — great job!
Pro Tips
- Take photos before disassembling so you remember how it goes back together.
- Bring the old washer or cartridge to the store to find an exact match.
- If the leak persists, the faucet seat may be damaged and need replacing.
