Backflow Preventer Repair and Rebuild in Hayden, ID
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.
Reduced Pressure Zone Assembly Service in Hayden, ID
RPZ assemblies protect against high-hazard cross-connections at restaurants, medical offices, car washes and buildings with chemical feed systems. They have two check valves and a relief port that discharges water if a check fails. We install, test and rebuild RPZ units from Watts, Febco, Wilkins and Apollo. Proper drainage is planned for the relief port discharge.
Freeze and Heat Protection for Backflow Preventers in Hayden, ID
Above-ground backflow assemblies are exposed to summer sun and winter cold. Frost reaches deep into the ground in colder areas, so water and sewer lines need to be buried well below the local frost line. 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.
