Frozen Pipe Prevention: How to Get Through a Cold Snap

A frozen pipe is dangerous because the ice expansion can split the pipe, and you don't find out until it thaws and floods. Preventing it during a cold snap takes four easy habits: let faucets drip, open cabinets, hold a steady temperature, and thaw safely if needed.

Should I let faucets drip in cold weather?

Yes — let faucets drip during extreme cold. A trickle of moving water is far less likely to freeze, and an open faucet relieves the pressure that actually bursts a pipe even if ice forms. Drip the faucets farthest from where your water enters, and especially any served by pipes on exterior walls.

Why open cabinet doors on cold nights?

Pipes under sinks — especially on exterior walls — sit in cold, closed cabinets. Open the cabinet doors on very cold nights so household heat reaches them. It's a small thing that keeps the most vulnerable pipes (kitchen and bathroom supply lines) a few critical degrees warmer.

Should I lower the thermostat when away in winter?

Not too far. Keep the thermostat consistent, even when you're away — never below about 55°F. Cranking the heat way down to save money lets pipes in walls and unheated spaces freeze, and a burst pipe costs far more than the savings. Consistent warmth is cheap insurance against a flood.

How do I thaw a frozen pipe safely?

If a pipe freezes, open the faucet it feeds and thaw it gently with a hairdryer, heat lamp, or towels soaked in warm water — never an open flame. A torch can burst the pipe or start a fire. Work from the faucet end toward the frozen section. If you can't reach it or it's already burst, shut off the water and call a plumber. Insulating those pipes ahead of time helps most.

Frequently asked questions

Which pipes freeze first?

Pipes in unheated spaces (basements, attics, garages, crawlspaces) and along exterior walls, plus outdoor faucets and sprinkler lines. Those deserve insulation and extra attention.

How do I know a pipe is frozen?

No or barely-a-trickle water from a faucet in cold weather, frost on a visible pipe, or odd smells from the drain. Act fast — open the faucet and start thawing before it bursts.
