Before a freeze (City checklist)
From the Dallas Water Utilities winter guide:
- Wrap exposed pipes outside or in unheated areas, including the attic
- Drain and remove garden hoses from outside faucets
- Insulate outdoor faucets with hard foam covers or cloth
- Cover foundation vents on pier-and-beam homes
- Learn how to operate your private shut-off valve
During subfreezing weather
Let hot and cold water drip slowly from inside faucets during a hard freeze, and open cabinet doors under sinks on outside walls. Turn off or confirm the freeze sensor on your irrigation system.
Dallas-specific weak spots
Attic water lines, pipes in exterior walls, garage water heaters and lines, and backflow preventers on irrigation systems are the usual failure points here.
