how to fix a leaky outdoor faucet

Introduction

A leaky outdoor faucet is more than just an annoyance—it can lead to wasted water, higher utility bills, and even damage to your home’s foundation if left unchecked. Fortunately, fixing a dripping or leaking spigot is a straightforward task that most homeowners can tackle with a few basic tools. In this guide, we’ll walk you through the common causes of outdoor faucet leaks and provide step-by-step instructions on how to repair them.

Common Causes of a Leaky Outdoor Faucet

Before diving into the repair process, it’s important to identify the root cause of the leak. Some of the most common reasons include:

  • Worn-out washers – Over time, the rubber washer inside the faucet can deteriorate, leading to leaks.
  • Loose packing nut – The packing nut, which helps create a watertight seal, may loosen over time.
  • Damaged O-rings – The O-ring inside the faucet handle can degrade, allowing water to seep through.
  • Cracked or frozen pipes – If your faucet has been exposed to freezing temperatures, the pipe or faucet itself may have developed cracks.

Tools and Materials Needed

Before starting the repair, gather the following tools and supplies:

  • Adjustable wrench
  • Flathead and Phillips screwdriver
  • Replacement washers and O-rings
  • Teflon (plumber’s) tape
  • Pipe wrench (if necessary)
  • Bucket or towel (to catch any remaining water)

Step-by-Step Guide to Fixing a Leaky Outdoor Faucet

Step 1: Turn Off the Water Supply

Before working on the faucet, shut off the water supply to prevent further leakage. The shut-off valve for outdoor faucets is usually located inside your home, near the point where the pipe connects to the faucet.

Step 2: Drain Any Remaining Water

Turn on the outdoor faucet to release any trapped water in the pipe. This prevents excess water from spilling when you remove parts of the faucet.

Step 3: Remove the Faucet Handle

Use a screwdriver to remove the screw securing the faucet handle. Gently pull the handle off to expose the packing nut and internal components.

Step 4: Tighten or Replace the Packing Nut

A loose packing nut is a common cause of leaks. Use an adjustable wrench to tighten it slightly and see if this stops the dripping. If the leak persists, you may need to replace the washer or O-ring inside.

Step 5: Inspect and Replace the Washer

  1. Remove the stem assembly – Unscrew the packing nut and pull out the faucet stem.
  2. Check the washer – Look for cracks or wear on the rubber washer at the end of the stem.
  3. Replace the washer – If damaged, swap it out with a new one of the same size.

Step 6: Inspect and Replace the O-Ring

If the faucet still leaks, inspect the O-ring inside the handle assembly. A worn-out O-ring can allow water to leak around the faucet handle. Replace it with a new one, applying a small amount of plumber’s grease to ensure a proper seal.

Step 7: Reassemble the Faucet

  1. Reinsert the faucet stem and tighten the packing nut.
  2. Reattach the handle and secure it with the screw.
  3. Wrap the faucet threads with Teflon tape before reattaching any additional components.

Step 8: Turn the Water Supply Back On

Slowly turn the water supply back on and test the faucet for leaks. If the leak persists, double-check that all components are securely in place.

Preventing Future Outdoor Faucet Leaks

To extend the life of your outdoor faucet and prevent future leaks, follow these simple maintenance tips:

  • Winterize your faucet – Disconnect hoses and use a faucet cover during freezing months to prevent pipe damage.
  • Regularly inspect for leaks – Check your outdoor faucet at least once a season for early signs of wear.
  • Avoid over-tightening the faucet – Excessive force can damage washers and O-rings, leading to leaks.

When to Call a Professional

If your faucet continues to leak after replacing the washers and O-rings, or if you suspect a cracked pipe, it may be best to call a professional plumber. A persistent leak could indicate deeper plumbing issues that require expert attention.

Conclusion

A leaky outdoor faucet is a common household issue, but with the right tools and a bit of patience, you can fix it yourself and save money on costly repairs. By identifying the cause, following these step-by-step repair instructions, and taking preventive measures, you can ensure your outdoor faucet remains in top shape for years to come.
