Reduced Pressure Zone Assembly Service in Sandpoint, 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.

Fire Line Backflow Testing in Sandpoint
Fire sprinkler systems typically use double check or double check detector assemblies to keep stagnant water out of the public supply. These assemblies need regular testing, often coordinated with fire system inspections. We test and repair fire line assemblies and document the results. We can coordinate scheduling with your fire protection contractor.
Freeze and Heat Protection for Backflow Preventers in Sandpoint, 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 for years.

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 usually used for low to medium hazard situations, like irrigation systems. The choice depends on the application and local code requirements.

A well-maintained backflow preventer can last 10 to 20 years or more. However, factors like water quality, exposure to weather, and the type of device can affect its lifespan. Frost reaches deep into the ground in colder areas, so water and sewer lines need to be buried safely below the local frost line. Regular testing and maintenance help lengthen its service life.
