Questions this calculator answers
- At what temperature do pipes freeze?
- Water freezes at 32°F, but a pipe in a heated house may not. Unheated crawl spaces, garages and sillcocks with hoses attached fail first. Duration and wind matter. This tool uses 20°F as a high-risk line for unheated pipes, which is a practical threshold, not a code figure.
- What do I do if a pipe bursts?
- Water off at the main. Then a plumber. Photograph before anything is torn out if you may claim.
