Pipe Protection Checklist
Let faucets drip slightly (cold & hot) when temps drop below 28°F.
Open cabinet doors under sinks to let warm air circulate around pipes.
Keep thermostat at 55°F or higher, even when away.
Insulate exposed pipes in attics, garages, and along exterior walls.
Disconnect and drain outdoor garden hoses.
Cover outdoor faucets with insulated faucet covers.
Austin Freeze Facts
Austin averages 15–25 freezing nights per year, mostly between December and February. Most are brief overnight freezes that thaw by mid-morning.
However, hard freeze events (sustained temperatures below 28°F for 4+ hours) occur 2–5 times annually and pose the greatest risk to pipes, plants, and outdoor pets. Bridges and overpasses freeze first.
The NWS issues Freeze Warnings when temperatures are expected to drop to 32°F or below and Hard Freeze Warnings for temperatures at or below 28°F.
