How to Repair a Leaking Outdoor Faucet Hose Bibb

By: Allen Lyle

Repairing a dripping outdoor spigot is often at the bottom of a homeowner’s to-do list, since the leak is outside the house. But left unchecked, it doesn’t take long for even a small leak from a hose bibb to waste hundreds of gallons of water.

Another common problem on outside spigots is leaking around the valve stem when the water is turned on. The good news is that both of these problems can often be easily fixed simply by tighten the packing nut behind the handle 1/8 to 1/4 turn.

If the faucet still leaks after tightening the packing nut, the washer on the end of the valve stem needs to be replaced. Here’s how to go about it:

  1. Turn the water off at the water meter using a cut-off key.
  2. Unscrew the packing nut beneath the handle of the faucet.
  3. Grasp the faucet handle, and pull the valve stem out of the hose bibb.
  4. Remove the screw on the valve stem holding the faucet washer.
  5. Replace the washer with one of the same size and thickness.
  6. Push the valve stem back into the hose bibb housing.
  7. Tighten the packing nut on the hose bibb until snug.
  8. Use the cut-off key to turn the water back on at the meter.
  9. Turn the spigot back on to remove any air from the line.
  10. Check for leaks around the packing nut on the valve stem.
  11. Turn the faucet off and check the spigot for leaks.
