Water lines freeze due to a combination of exposure to subfreezing temperatures and poor insulation. When the ambient temperature around the pipes drops below 32°F (0°C), the water inside can freeze, expand, and potentially cause the pipes to burst. Preventive measures include insulating pipes, especially those in unheated areas like basements, attics, and garages, and keeping garage doors closed. Also, letting faucets drip slightly can prevent pressure build-up and reduce the risk of bursting pipes.
