How to Adjust a Set Screw in an Outdoor Water Spigot

Attach a garden hose to the outdoor water spigot to divert water while you adjust the set screw.

Rotate the spigot handle counterclockwise to fully open the water supply. Tighten the set screw with a Phillips-head screwdriver and turn the handle clockwise to turn the water off. Check the handle to ensure it is tight.

Turn off the water supply to the outdoor water spigot, if the set screw does not tighten securely. The shutoff is either under the house in line with the spigot plumbing pipe or in the house usually in a basement or laundry room.

Open the spigot handle fully to allow any remaining water in the line to drain. Leave the faucet handle in the open position. Remove the set screw with a Phillips-head screwdriver.

Apply some thread sealant or plumber's tape to the threads of the set screw. Install the set screw back into the center of the handle and tighten with the Phillips-head screwdriver. Turn the water supply back on to the outdoor spigot.
