How to Fix a Leaky Outdoor Spigot and Stop Water Waste

A leaky outdoor spigot wastes water and raises your utility bills, but you can fix it yourself without calling a plumber right away. Most leaks come from worn washers, loose packing nuts, or damaged connections. By identifying the leak’s source, safely shutting off the water, and replacing or tightening the right parts, you can stop the drip quickly and efficiently.

How can I tell where the leak is coming from?

To find where your outdoor spigot is leaking, watch it both when it’s off and when water is running. Check three areas closely: the handle, the pipe connection where the spigot meets the house, and the spout. If water drips near the handle, the packing nut or stem packing is likely worn. A leak at the pipe connection indicates a loose or damaged fitting. If water drips from the spout even when the handle is fully off, the washer inside the valve probably needs replacement. You can also run your fingers along these parts to feel for moisture or water trails. This simple check helps you focus your repair efforts on the right spot.

What usually causes an outdoor spigot to leak?

The most frequent cause is a worn or damaged washer. Washers degrade over time from constant pressure and exposure to weather, allowing water to seep through. Another common issue is a loose or damaged packing nut, which seals the valve stem and prevents leaks around the handle. If the packing wears out, water can drip near the handle. Freezing temperatures can crack or damage internal parts, causing leaks when the water thaws. Corrosion or mineral buildup inside the valve can also stop it from closing fully, leading to drips. Knowing these causes helps you target the right parts for inspection and repair.

How do I safely prepare to fix my leaking spigot?

Before you start, shut off the water supply to the outdoor spigot to avoid flooding. Find your home’s main water shutoff valve or a separate valve for the outdoor spigot—these are often in the basement, crawl space, or near the water meter. Turn off the valve, then open the spigot fully to drain any remaining water. Gather these tools and materials: an adjustable wrench, flathead and Phillips screwdrivers, replacement washers or packing material (from hardware stores), plumber’s tape, and a cloth for grip. Lay down towels or place buckets under the spigot to catch drips and keep your workspace clean. Taking these steps will make your repair safer and smoother.

What are the step-by-step instructions to fix a leaky outdoor spigot?

1. Confirm the water is shut off and the spigot is drained.

2. Remove the handle screw with a screwdriver and take off the handle.

3. Use a wrench to loosen the packing nut (the hexagonal nut behind the handle). If water leaks from the handle, gently tightening this nut can stop the drip.

4. If tightening doesn’t stop the leak, fully unscrew the packing nut and pull out the valve stem.

5. Check the washer at the stem’s end. Replace it if it’s worn, cracked, or flattened with a new washer of the same size.

6. Inspect the packing material around the stem. Replace or add fresh packing if it looks old or brittle.

7. Wrap plumber’s tape around the valve stem threads before reinserting it.

8. Screw the stem back into the spigot body and tighten the packing nut snugly—avoid overtightening, which can cause leaks.

9. Reattach the handle and tighten its screw.

10. For leaks at the pipe connection, carefully tighten the fitting with a wrench or replace the sealing tape or gasket if needed.

How do I check that my repair worked and the leak is gone?

After completing the repair, slowly turn the water supply back on. Watch the spigot for any dripping from the handle, pipe connection, or spout. Run water through the spigot for a minute to confirm it opens and closes smoothly without leaks. If you still notice drips, try gently tightening the packing nut a bit more. Persistent leaks after replacing washers and packing might mean the valve seat inside the spigot is damaged, requiring more advanced repairs or replacement. Your repair worked if there’s no drip when the spigot is off and no leaks when it’s running.

How can I prevent my outdoor spigot from leaking in the future?

Regular maintenance helps prevent leaks and extends your spigot’s life. Check the spigot each spring and fall for drips and tighten the packing nut if needed. Replace washers before they wear out completely. Winterize your spigot by shutting off its water supply and draining it to avoid freeze damage. Installing a frost-free spigot can also reduce freezing-related leaks. Avoid overtightening the handle when turning off the water, since that wears washers prematurely. Keep the spigot clean and free from mineral buildup to maintain a proper seal. These steps reduce the chance of leaks developing over time.

Conclusion

Fixing a leaky outdoor spigot usually means finding the leak’s source, shutting off water safely, and replacing worn washers or packing. With basic tools and the steps above, you can stop most leaks yourself and save water and money. If leaks continue after these repairs, consider replacing the spigot or calling a plumber. Regular maintenance and winterizing will help keep your spigot working well and prevent future leaks.
