Backflow Preventer Repair and Rebuild in Harrisburg, SD

Rebuilding usually costs far less than replacing the entire assembly.
Freeze and Heat Protection for Backflow Preventers in Harrisburg, SD
Above-ground backflow assemblies are exposed to summer sun and winter cold. Frozen pipes are a real and regular risk in South Dakota, with deep frost each winter that can reach water service lines buried at shallow depth. 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.
