Reduced Pressure Zone Assembly Service in Winston-Salem, 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.

Sprinkler and drip systems are one of the most common sources of cross-connection risk because they sit in soil with fertilizers and pesticides. Many systems use a pressure vacuum breaker or a reduced pressure assembly installed above grade. We size and install the correct device and set it at the required height. Insulated covers or enclosures help protect it from weather and theft.

Commercial Backflow Compliance in Winston-Salem

Property managers receive a summary of every device and its status. This keeps you ahead of notices and avoids surprise shutoffs.

Freeze and Heat Protection for Backflow Preventers in Winston-Salem, 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 longer.
