With frigid temperatures expected in Alabama for much of the week, reports of frozen pipes - and damage from burst pipes - are growing.
Freezing temperatures can cause massive problems with plumbing since water expands when it turns to ice. The expansion puts pressure on whatever is containing it, including metal or plastic pipes. Eventually, if the pressure reaches maximum level, the expanding water can cause the pipe to break.
Pipes in most danger of freezing are those exposed to severe cold, including outdoor hose bibs, swimming pool supply lines and water sprinkler lines. Pipes in unheated areas like basements and crawl spaces, attics, garages or kitchen cabinets are also vulnerable, as are pipes that run against exterior walls that have little or no insulation.
The Red Cross has advice on preventing frozen pipes and what to do if they do freeze.
