Frost-Proof Outside Spigots - Chicago Plumbing Information

Frost-proof outside spigots or hydrants are common, and they prevent many repairs each year. To keep the water behind the valve from freezing, the valve portion of the spigot is located deep inside the wall. When the spigot is in the off position, no water is present near the outside of the house wall. Unfortunately, some homeowners unknowingly defeat the purpose of the design by leaving a water-filled hose attached to the spigot. As the water in the hose and spigot freezes, it expands, cracks the spigot, and creates a burst-pipe situation in the wall. Remember to remove the hose from the spigot and drain it before the cold season.
