Freeze and Heat Protection for Backflow Preventers in Porterville, CA
Above-ground backflow assemblies are exposed to summer sun and winter cold. Freezing is uncommon along the coast and on valley floors in Northern California, but frosty nights do happen and can crack unprotected outdoor pipes. 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 longer.

Proper drainage is designed for the relief port discharge.
