Freeze and Heat Protection for Backflow Preventers in Brookhaven, WV
Above-ground backflow assemblies are exposed to summer sun and winter cold. Keeping heat on in unused rooms and letting faucets drip on the coldest nights helps prevent many frozen pipe calls. 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.
