How to Fix a Leaky Faucet in 6 Simple Steps

A dripping faucet isn't just annoying—it can waste up to 3,000 gallons of water every year. Luckily, most leaks are easy to repair with basic tools. In this tutorial we'll walk you through the entire process from diagnosis to cleanup.

Tools & Materials

- Adjustable wrench or basin wrench

- Flat-head & Phillips screwdrivers

- Replacement O-rings / cartridge (check manufacturer)

- Cloth or rag to cover drain

- White vinegar & old toothbrush for mineral deposits

Step-by-Step Repair Guide

### 1. Turn Off the Water

Locate the shut-off valves underneath the sink and turn them clockwise. Open the faucet to release any pressure.

### 2. Plug the Drain

Small screws can disappear quickly—use a rag or rubber stopper to block the drain.

### 3. Disassemble the Handle

Most handles have a decorative cap hiding the screw. Pry it off with a flat-head screwdriver, then remove the handle.

### 4. Inspect the Cartridge or Washer

Pull the cartridge straight out (for cartridge faucets) *or* unscrew the packing nut to reveal the rubber washer (for compression faucets). Worn O-rings or cracked washers are the usual culprits of leaks.

### 5. Replace Worn Parts

Coat new O-rings with plumber's grease and seat them firmly. For cartridge models, take the old cartridge to the hardware store to ensure an exact match.

### 6. Reassemble & Test

Rebuild the faucet in reverse order, open the shut-off valves, and test. A steady stream without drips means success!

Prevent Future Leaks

1. Avoid overtightening the handles—this stresses washers.

2. Clean aerators every 3–6 months to prevent mineral buildup.

3. Replace cartridges every 5–7 years as preventative maintenance.

When to Call a Professional

If the valve seat is pitted or corroded, or you see signs of extensive rust on supply lines, it's best to let a licensed plumber handle the repair.

Conclusion

Fixing a leaky faucet takes less than 30 minutes and costs only a few dollars in parts, yet it can save hundreds of gallons of water. Next time you hear that tell-tale drip, grab your tools and follow these steps.
