How to Winterize Outdoor Faucets

Faucets are the most vulnerable points of your home's exterior plumbing when the temperature drops. When water trapped in the spigot or the pipe leading to it freezes, it expands with enough force to crack the copper or plastic line, leading to a major leak once the thaw begins. Successfully winterizing your system is about removing the internal pressure and creating a thermal barrier. Do this before the first hard freeze, and you will save yourself the headache of a basement flood and the high cost of emergency plumbing repairs in mid-winter.

1. Trap Water Before It Freezes. Unscrew any garden hoses attached to the outdoor spigots. Drain the hoses completely, coil them, and store them in a garage or shed.
2. Cut Off the Water Supply. Locate the shut-off valve inside your basement or crawlspace that controls the outdoor faucet. Turn the handle clockwise until it stops.
3. Release All Trapped Water. Head back outside and open the outdoor faucet completely to let any water sitting in the line drain out. Leave the valve in the open position.
4. Seal Out the Cold. Place a foam or insulated hard-shell faucet cover over the exterior spigot. Tighten the draw-string or locking mechanism to ensure a snug fit against the siding.
5. Confirm the Seal Holds. Go back inside and inspect the pipe near the interior shut-off valve for any moisture or slow drips. If you see water, tighten the packing nut on the valve.
6. Complete Your Winter Defense. Perform a final walkthrough of all exterior spigots, including those in the backyard and side yard. Ensure all are covered and hoses are cleared.
