Outdoor Faucet Winterizing Checklist for Homeowners

Before freezing weather, disconnect outdoor hoses, protect exposed piping and identify any indoor shutoff serving the faucet. The right drain-down procedure depends on the faucet and valve; a frost-free faucet reduces risk but is not immune to freezing.

Before the first freeze

1. Turn off the outdoor faucet, disconnect the hose and any attachments, drain the hose and store it under cover. A connected hose can interfere with drainage from a frost-free faucet.
2. Locate an indoor shutoff dedicated to that faucet, if present. If it operates normally, close it and open the outside faucet to drain the isolated section. Use a drain or bleeder only if the valve is designed for it and you understand its operation; catch the water. Do not force a stuck or corroded valve.
3. Insulate exposed pipes in unheated areas and fit an outdoor faucet cover where appropriate. Insulation slows heat loss; it cannot guarantee protection during prolonged cold.
4. Know where the main shutoff is before an emergency. If a valve leaks or will not move, arrange service before freezing weather.

Frost-free faucets and spring checks

A frost-free sillcock has a longer stem intended to shut off water inside the warmer wall. It must be installed so it can drain; remove the hose even if the faucet is labeled frost-free. If you are unsure about its slope, installation or a dedicated shutoff, ask a plumber rather than altering the piping.

When returning the faucet to service, watch both the exterior and the accessible interior connection while it runs. A split can leak inside the wall only when the faucet is open. Stop using it and call a plumber if you see moisture, a weak stream with unexplained leakage, or water damage.
