JONESBORO — With temperatures taking a sudden plunge, the possibility of burst water pipes are on everyone’s mind. Officials are offering tips to help residents avoid the messy and often expensive issue of busted pipes. Pipes that freeze most frequently are those that are exposed to severe cold, like outdoor hose bibs, swimming pool supply lines, water sprinkler lines and 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 are also subject to freezing.
