Backflow Testing and Certification in Cary

Most water providers require testable backflow assemblies to be certified at installation and then once a year. Our certified testers check each valve's opening point, relief valve operation and differential pressure. If a device fails, we can repair or rebuild it right away with genuine parts. We submit passing results so you avoid compliance letters or service interruption.

Double Check Valve Assembly Installation in Cary

Double check assemblies are used for low hazard connections such as many fire sprinkler systems and some irrigation lines. They have two spring-loaded check valves and test cocks for annual certification. Unlike an RPZ, they do not discharge water, so they can be installed in vaults or below grade where local rules allow. We size them to avoid excessive pressure loss on your system.

Reduced Pressure Zone (RPZ) Assembly Installation in Cary

RPZ assemblies offer the highest level of backflow protection and are commonly required for high-hazard applications in Cary. These devices feature two independent check valves and a relief valve that opens to discharge water if pressure differentials indicate a backflow condition. HFN Plumbing specializes in precise RPZ installation, with proper sizing, placement and testing to meet all regulatory requirements for residential and commercial properties. We work with trusted brands like Watts and Febco.

Commercial Backflow Preventer Installation in Cary

Restaurants, salons, dental offices and light industrial buildings often need multiple backflow devices on soda machines, boilers, dishwashers and process water. We survey the building, identify each cross-connection and install containment and isolation assemblies as required. Work is scheduled after hours or on weekends when needed to keep from shutting down your business. You receive documentation for each device for your records and your water provider.

Double Check Valve Assembly (DCVA) Installation in Cary

The double check valve assembly, or DCVA, is a widely used backflow preventer for low-hazard applications where the consequences of backflow are not severe.

Our certified plumbers precisely install these devices, making sure both check valves operate correctly and are properly sealed to prevent backpressure or back-siphonage into the main water supply.
