Commercial Backflow Prevention Systems in Winston-Salem, NC
Businesses in Winston-Salem, NC carry a greater responsibility to prevent water contamination because of the scale and complexity of their plumbing systems.

Reduced Pressure Zone (RPZ) Device Installation in Winston-Salem, NC
For high-hazard applications in Winston-Salem, NC where toxic substances could contaminate the water supply, a reduced pressure zone, or RPZ, device is usually required. RPZ backflow preventers offer the highest level of protection, using a relief valve to discharge water if the pressure drops. HFN Plumbing specializes in RPZ installation, making sure all components are correctly sized, positioned and set up according to state and local plumbing codes. Proper installation is critical for effective operation.
Double Check Valve Assembly Installation in Winston-Salem
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 permit. We size them to avoid too much pressure loss on your system.
Backflow Preventer Installation Cost Comparison in Winston-Salem, NC
A residential pressure vacuum breaker is the most affordable option, while larger RPZ assemblies for commercial buildings cost a good deal more in parts and labor. Size, brand, enclosure needs and how much existing pipe must be modified all affect the price. Replacing a failed old device with a new one is usually cheaper than repeated rebuilds. We give you an itemized quote that includes the initial certification test.
Code-Compliant Backflow Installation in Winston-Salem, NC
Sorting out the plumbing codes for backflow prevention in Winston-Salem, NC can be challenging. HFN Plumbing stays up to date with local and state regulations so every installation is fully compliant. North Carolina enforces a statewide plumbing code based on the International Plumbing Code, and plumbing contractors must be licensed by the state. From proper device selection and placement to required permits and inspections, we handle all aspects of code compliance. Your system works as intended and avoids fines or costly rework down the line.
Commercial Backflow Preventer Installation in Winston-Salem
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.
Backflow Prevention for Irrigation Systems in Winston-Salem, NC
Irrigation systems in Winston-Salem, NC are a frequent source of backflow, as stagnant water and lawn chemicals can be drawn back into the potable water supply.
