Freeze and Heat Protection for Backflow Preventers in Dover, NH
Above-ground backflow assemblies are exposed to summer sun and winter cold. Winterizing unused buildings, draining outdoor faucets and keeping heat on avoid most of the freeze damage plumbers see. 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.
Backflow Preventer Repair and Rebuild in Dover, NH
Common failures include worn check valve rubbers, debris stuck under seats and relief valves that drip constantly. We isolate the assembly, disassemble it and replace the worn parts with the manufacturer rebuild kit. Then we retest to verify it passes. Rebuilding usually costs much less than replacing the entire assembly.

Most municipalities, including Dover, require backflow preventers to be tested once a year. This regular testing makes sure the device is working correctly and continues to protect your potable water supply from contamination, as required by local water authorities.
An RPZ, or Reduced Pressure Zone assembly, offers the highest level of protection, suitable for high-hazard cross-connections. A DCVA, or Double Check Valve Assembly, provides moderate protection and is typically used for low to medium hazard situations, like irrigation systems.
