Reduced Pressure Zone Assembly Service in Raleigh, NC
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 designed for the relief port discharge.

Freeze and Heat Protection for Backflow Preventers in Raleigh, NC
Above-ground backflow assemblies are exposed to summer sun and winter cold. Hard freezes are uncommon along the coast but happen most winters in the mountains, where pipes in crawlspaces and outside walls require protection. 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.
