To repair a leaking outdoor faucet, you need to shut off the water supply, identify whether the leak comes from the handle, the spout or the base, and replace the worn washer, packing or valve seat. Most of these repairs take an hour or two with a few basic tools. This guide walks through the process for the common compression-style hose bibb that causes most outdoor drips.

Shut Off the Water and Relieve Pressure

Start by closing the shutoff valve that feeds the outdoor faucet. This is usually inside the basement, crawl space or near the exterior wall. If you cannot find one, shut off the main water supply. Then open the outdoor faucet fully and let any trapped water drain out, which relieves pressure in the line.

Find Where the Leak Is Coming From

The location of the leak tells you which part has failed. Each area points to a different repair:

  • Dripping from the spout when closed: The washer or valve seat is worn.
  • Water leaking around the handle: The packing nut or O-ring is loose or worn.
  • Water seeping at the base or wall: The packing or the faucet body has cracked, which usually needs a full replacement.

How to Repair an Outdoor Faucet Leak Step by Step

Once you know the source, work through the repair in this order:

  1. Remove the handle screw and lift off the handle.
  2. Unscrew the packing nut with an adjustable wrench and pull out the stem.
  3. Remove the rubber washer at the bottom of the stem. Note its size and shape, then take it to a hardware store to match it.
  4. Install a new washer, secured by the brass screw. Tighten it snugly without forcing it.
  5. Replace the packing washer or O-ring on the stem if it looks cracked or flattened.
  6. Reassemble the stem, packing nut and handle, then slowly turn the water back on.

Check the Valve Seat

If the faucet still drips after the new washer is in, the valve seat inside the faucet body may be pitted or corroded. A seat wrench can resurface it, or you can replace the whole valve. Manufacturers generally recommend replacing the seat when the surface shows deep grooves rather than light wear.

Tools and Supplies You Will Need

  • Adjustable wrench or pipe wrench
  • Phillips or flathead screwdriver
  • Replacement washer (matched to size)
  • Replacement O-rings or packing washer
  • Seat wrench (if resurfacing the valve seat)
  • Plumber’s grease and a rag
  • Outdoor faucet washer assortment: Having several sizes on hand lets you match the old washer without a second trip to the store. View on Amazon
  • Seat wrench set: A set with several bit sizes helps you remove and resurface a worn valve seat. View on Amazon
  • Plumber’s grease: A small tube keeps O-rings sealed and makes the stem easier to turn. View on Amazon

Common Mistakes to Avoid

  • Skipping the step of draining the line, which can cause water to spray when you loosen the packing nut.
  • Buying a washer by eye instead of measuring the old one, which often leads to a poor seal.
  • Overtightening the packing nut, which can crack the stem or make the handle hard to turn.
  • Forgetting to turn the water back on slowly, which can cause a sudden surge that damages fittings.

FAQ

Can I repair an outdoor faucet leak without shutting off the main water?

Yes, if the faucet has its own shutoff valve inside the building. Closing that valve isolates the outdoor line, so the main supply can stay on.

How long does a washer last on an outdoor faucet?

Washers wear out with use and freeze-thaw cycles, and many owners find they need replacing every few years. Replace it sooner if you see drips at the spout.

When should I replace the whole faucet instead of repairing it?

Replace the faucet if the body is cracked, the threads are stripped or water leaks from the base. If you are unsure about the connections or the shutoff valve, consult a licensed plumber.

Conclusion

Most outdoor faucet leaks come from a worn washer, a loose packing nut or a damaged valve seat, and each is a manageable repair. Work methodically, match your parts carefully and turn the water back on slowly. If the leak persists or the problem involves the main supply, a professional can finish the job safely.
