Your frozen pipes checklist
- Disconnect, drain, and store garden hoses, then shut off and drain any interior valves that feed outdoor faucets.
- Insulate exposed pipes in the garage, crawl space, and along exterior walls with foam sleeves rated for the pipe size.Helpful gear: Foam pipe insulation sleeves — Recommended pick
- On nights in the low 20s, let a pencil-thin stream of water drip from the faucet farthest from where the line enters.
- Open cabinet doors under kitchen and bathroom sinks on outside walls so household heat reaches the plumbing.
- Add self-regulating heat cable to the runs most likely to freeze, such as a pipe in an unheated garage.Helpful gear: Self-regulating heat cable — Recommended pick
- Cap outdoor faucets with insulated covers once the hoses are off.Helpful gear: Outdoor faucet covers — Recommended pick

- If you travel, keep the thermostat at 55°F or higher and ask someone to check the house during a cold snap.Helpful gear: Wi-Fi water leak sensor — Recommended pick
