Project

Now, reassemble the faucet in the reverse order of disassembly. Slide the packing nut back over the valve stem and thread it onto the faucet body. Start by hand-tightening it clockwise. Then, use your adjustable wrench to snug it down another half-turn. The goal is to compress the new packing material to create a seal, but not make it so tight that the valve stem cannot turn. Place the faucet handle back on the valve stem, making sure it's oriented correctly (usually with the 'off' position fully clockwise). Insert the handle screw and tighten it firmly with your screwdriver.

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.
