Introduction

A leaking outdoor faucet can be more than just an annoying drip—it can waste water, increase your utility bills, and even cause damage to your home’s foundation if left unchecked. Fortunately, fixing a leaky outdoor spigot is a simple DIY task that requires minimal tools and effort. 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 Leaking Outdoor Faucet

Before diving into the repair process, it’s important to understand why your outdoor faucet is leaking. Here are some of the most common reasons:

1. Worn-Out Washer

Over time, the rubber washer inside the faucet can deteriorate, leading to leaks.

2. Loose or Damaged Packing Nut

The packing nut secures the faucet’s stem. If it’s loose or damaged, water can seep through.

3. Faulty Valve Seat

Corrosion or buildup on the valve seat can prevent a proper seal, causing leaks.

4. Cracked or Frozen Pipes

If your outdoor faucet leaked after a cold winter, frozen water might have caused internal cracks.

How to Fix a Leaking Outdoor Faucet

Follow these step-by-step instructions to fix your leaky outdoor faucet efficiently.

Step 1: Turn Off the Water Supply

Before starting any repair, locate your home’s main water shut-off valve and turn it off to prevent flooding.

Step 2: Drain the Faucet

Once the water is off, open the outdoor faucet to drain any remaining water. This prevents spills when you take it apart.

Step 3: Remove the Faucet Handle

  • Use a screwdriver to unscrew the handle.
  • Gently pull the handle off to expose the faucet stem.

Step 4: Unscrew the Packing Nut

  • Use an adjustable wrench to loosen the packing nut.
  • Once removed, pull out the faucet stem.

Step 5: Inspect and Replace the Washer

  • Check the rubber washer at the bottom of the stem. If it’s worn or cracked, replace it with a new one.
  • Ensure you use the correct size washer for a proper seal.

Step 6: Check the Packing Nut and Valve Seat

  • Inspect the packing nut for damage and replace it if necessary.
  • Look inside the faucet body to check the valve seat. If it’s corroded, clean it with vinegar and a brush or replace it if needed.

Step 7: Reassemble the Faucet

  • Place the new washer onto the stem.
  • Reinsert the faucet stem and tighten the packing nut securely.
  • Reattach the handle and screw it back in place.

Step 8: Turn the Water Supply Back On

  • Slowly turn the main water supply back on.
  • Check for any remaining leaks and ensure the faucet is functioning properly.

Preventing Future Leaks

To avoid dealing with a leaky outdoor faucet in the future, follow these preventative measures:

  • Turn Off Water Before Winter – If you live in a cold climate, shut off the outdoor water supply and drain the faucet to prevent freezing.
  • Use a Faucet Cover – A protective cover can shield your faucet from extreme temperatures.
  • Check for Leaks Regularly – Periodically inspect your outdoor faucet for drips, cracks, or wear.

Conclusion

Fixing a leaky outdoor faucet is a quick and easy task that can save you money and prevent potential water damage. By following these step-by-step instructions, you can repair your faucet in no time.
