To repair an outdoor faucet and prevent it from leaking, individuals usually need to remove the valve stem assembly and replace it with a new one. Tightening loose packing nuts or packing washers may also stop the leaking. To repair an outdoor faucet, a couple of tools such as an adjustable wrench and 4-in-1 screwdriver are required.
In most cases, leaks in outdoor faucets occur in the spout or the handle. If a leak is present in the spout, remove and replace the valve stem assembly. For leaks that occur in the handle, try to tighten the packing nut with the help of a wrench before replacing the valve stem assembly.
To remove and replace the valve stem assembly, turn off the water supply and use a screwdriver to unscrew the screw holding the assembly in place. A packing nut is usually located behind the handle. With the help of the adjustable wrench, turn the packing nut counter clockwise and slide it out of the assembly. Next, replace the valve stem assembly with a new one, making sure it is a good match for that particular type of outdoor faucet. Screw the handle of the faucet back on and test it by turning the water supply on.
