Worry about pipes freezing when outdoor temperatures drop below 32°F (0°C), as water inside pipes can begin to freeze under prolonged exposure.

Key Risk Thresholds

Pipes face higher risk below 20°F (-7°C), especially if sustained for several hours or days, leading to expansion and potential bursts. Exposed or uninsulated pipes in areas like basements, attics, garages, or near exterior walls freeze faster.

Vulnerable Pipes

• Outdoor hose bibs, pool lines, and sprinkler pipes.
• Those in unheated spaces or against exterior walls with poor insulation.

Freezing can occur in as little as 6 hours at subfreezing temperatures, though bursts often follow 1-3 days of cold.
