Steps to Fix a Leaky Faucet

Step 1: Turn Off the Water Supply

Ensure you turn off the water supply to your faucet. Look under the sink for the water supply valves and turn them clockwise to close. Open the faucet to release any water left in the line.

Step 2: Plug the Drain

Use a sink plug or a rag to block the drain. This prevents small parts like screws or washers from falling down the drain during your repair.

Step 3: Remove the Faucet Handle

Remove the handle by loosening the screw that holds it. This screw is usually hidden under a decorative cap on the top of the handle. Use a flat-head screwdriver to gently pry off the cap, then use a Phillips screwdriver to remove the screw.

Step 4: Take Out the Stem or Cartridge

With the handle off, use an adjustable wrench to remove the nut that holds the stem or cartridge in place. Carefully pull out the stem or cartridge from the faucet body.

Step 5: Replace the Washer and O-Ring

Inspect the stem or cartridge for worn-out washers or O-rings. Replace these with new ones that match in size and type. Apply a small amount of plumber's grease on the new washer and O-ring before installation.

Step 6: Reassemble the Faucet

Once the new washer and O-ring are in place, reinsert the stem or cartridge into the faucet body. Secure it with the nut and reattach the handle.

Step 7: Test Your Work

Turn the water supply back on and test the faucet for leaks. If it still leaks, you may need to disassemble again and check if the washer and O-ring are properly seated or if another part needs replacement.
