Freeze and Heat Protection for Backflow Preventers in Severn, MD

Above-ground backflow assemblies are exposed to summer sun and winter cold. Freezing nights are a normal part of winter in Maryland, and the western mountain counties see longer, harder cold spells than the coast. 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.
