The final step is to test your work. Go back to the shut-off valve and open it slowly and completely. Return to the outdoor faucet and inspect the packing nut area closely for any signs of water drips or seepage. Turn the faucet on and let water flow, then turn it off again. Check for leaks in both the on and off positions. If a small drip appears from the packing nut, use your wrench to give it one last, very slight (1/8 turn) tightening. If the leak is gone and the handle operates smoothly, the repair is complete.

This guide provides step-by-step instructions for fixing a common leak on an outdoor faucet (spigot or hose bibb) that originates from the packing nut located behind the handle. The process involves first attempting to tighten the nut, and if that fails, replacing the internal packing material (either a washer or twine) to create a new seal.

Frequently Asked Questions

What's the absolute first and most important step to take before attempting this repair?

You must turn off the main water supply to your house or the specific line feeding the outdoor faucet. Failing to do so can result in significant water damage and a much larger plumbing emergency. After turning off the supply, open the faucet to drain any remaining water from the line.

Do I really need the specific branded tools and materials listed, or can I use alternatives?

While the listed items are recommended for convenience, you generally only need an adjustable wrench and a screwdriver (a flathead is common for older spigots). For packing, standard faucet packing washers of the correct size or specialized graphite/Teflon packing cord can often substitute jute twine if the Danco washers aren't available. Always ensure your tools are the correct size to avoid stripping nuts.

I tried tightening the packing nut, but the leak is still there. What should I do next?

If tightening doesn't resolve the leak, it indicates that the internal packing material (whether it's a washer or twine) is worn out and needs replacement. Proceed to disassemble the faucet handle and packing nut, then carefully remove the old packing and install new material as detailed in the project steps. This usually provides a lasting fix.

How can I be certain the leak is coming specifically from the packing nut and not another part of the faucet?

Thoroughly dry the entire faucet body and surrounding area with a shop towel. Then, turn the water on to the faucet and carefully observe where the water first appears. If it's dripping or seeping directly from behind the handle, around the stem where the packing nut is located, then the packing nut is indeed the source of the leak.
