Garden hose spigots allow easy access to water outside your home, enabling you to irrigate your flowers and grass to keep them healthy during periods of drought. After years of use, your spigot may begin to leak, or maybe it does not shut the water off completely. It must be replaced so it doesn't waste water. You'll need a few simple plumbing tools and supplies to complete this task.
Turn off the main water supply valve in your basement. Follow your water piping back to where it enters your home; you should see a valve.
Apply spray lubricant to the spigot where it connects to the water pipe to loosen any rust on the threads.
Open the outside spigot valve all the way to drain out remaining water in the piping.
Place one pipe wrench on the water pipe and the other on the spigot. While grasping the wrench on the water pipe to hold it steady, grasp the pipe wrench on the spigot and turn it counterclockwise to loosen the spigot. Once loose, unscrew it the rest of the way by hand.
Brush the threads on the pipe with a stiff-bristled brush.
Wrap Teflon pipe thread tape around the threads of the water pipe clockwise until the threads are covered with two to three layers of tape.
Screw the new spigot on to the water pipe and turn it clockwise until it is hand-tight. Place one pipe wrench on the water pipe and one on the spigot. Hold the wrench on the water pipe steady and turn the wrench on the spigot clockwise until the spigot is tight. Make sure the spigot is pointing in the direction you desire when finished.
Turn the main water valve back on. Turn on the spigot and check for leaks.
