Freeze and Heat Protection for Backflow Preventers in Winslow, ME
Above-ground backflow assemblies are exposed to summer sun and winter cold. Frozen pipes are a serious winter risk across Maine, and pipes in exterior walls, crawlspaces, and unheated areas are the most at risk. Freezing can crack bodies and bonnets, while UV exposure breaks down plastic parts. We install insulated pouches, heated enclosures or lockable cages as needed. Protecting the assembly helps it pass testing and last for years.
