What the sources say
The City's guidance (Dallas Water Utilities winter guide) tells residents to drip faucets during a "hard freeze" and does not set a temperature threshold. We have not found an official Dallas number and will not invent one.
Risk factors
- Hours below freezing, especially overnight into the next day
- Wind against exterior walls
- Uninsulated attic, garage or crawlspace lines
- Outdoor faucets and irrigation backflow devices
Practical rule
When a forecast calls for sustained subfreezing temperatures, follow the full freeze checklist.
