How to Fix a Leaky Faucet in 15 Minutes

A dripping faucet wastes water, drives up your bill, and keeps you up at night. The good news: most leaks come from a worn washer or O-ring, and you can swap it out in about 15 minutes with a few basic tools. Here's how.

What You'll Need

• Adjustable wrench

• Screwdriver (flathead or Phillips, depending on your faucet)

• Replacement washer, O-ring, or cartridge (match it to your faucet model)

• Plumber's grease

• A rag or towel

Step-by-Step Instructions

1. Shut off the water supply. Look under the sink for the shut-off valves and turn them clockwise until snug.

2. Open the faucet to release pressure. Let any remaining water drain out, then plug the drain so small parts don't fall in.

3. Remove the handle. Pop off the decorative cap, unscrew the handle screw, and lift the handle away.

4. Take out the cartridge or stem. Use your wrench to loosen the packing nut, then pull out the valve stem or cartridge.

5. Inspect and replace the worn part. Swap the old washer, O-ring, or cartridge for a new one that matches.

6. Add plumber's grease. A thin coat on the new O-ring or washer helps it seal and last longer.

7. Reassemble the faucet. Reverse your steps: stem or cartridge back in, packing nut tightened, handle screwed on, cap snapped back.

8. Turn the water back on and test. Open the valves slowly and check for leaks at the handle and spout.

If the drip continues after you've replaced the washer or cartridge, the issue may be a worn seat or valve body, and it's worth calling a plumber. But for most leaky faucets, this quick fix will have your sink drip-free in about 15 minutes.
