Preventing and Thawing Frozen Pipes
Why Pipe Freezing is a Problem
Water has a unique property in that it expands as it freezes. This expansion puts tremendous pressure on whatever is containing it, including metal or plastic pipes. No matter the strength of a container, expanding water can cause pipes to break.
Pipes that freeze most frequently are:
- Pipes that are exposed to severe cold, like outdoor hose bibs, swimming pool supply lines, and water sprinkler lines.
- Water supply pipes in unheated interior areas like basements and crawl spaces, attics, garages, or kitchen cabinets.
- Pipes that run against exterior walls that have little or no insulation.
