Locate the interior shut-off valve for the outdoor faucet, which is typically found in the basement, crawl space, or a utility room directly behind the exterior spigot. Turn the valve handle clockwise until it is fully closed. If there is no dedicated shut-off, you must close the main water valve for the entire house. After closing the valve, go outside and open the spigot to drain any remaining water from the pipe. Place a bucket under the interior valve if it has a drain cap (bleeder valve) and open it to drain residual water from the indoor pipe section.
