Reduced Pressure Zone Assembly Installation in Naperville, IL
RPZ assemblies offer the highest level of protection and are required for high hazard connections like commercial kitchens, medical facilities, chemical injection and car washes. They include two independent check valves with a relief valve that dumps water if either check fails. Because the relief valve can discharge, we plan for drainage and install the assembly above grade where it can be tested easily. We carry trusted brands like Watts, Febco, Wilkins and Apollo.

Commercial Backflow Prevention in Naperville, IL
Commercial properties in Naperville, IL often have complex plumbing systems that pose a higher risk of cross-contamination and need robust backflow prevention. Restaurants, hospitals, industrial facilities and even multi-family buildings must comply with commercial plumbing codes. HVM Plumbing provides complete installation of heavy-duty backflow preventers, including large diameter RPZ assemblies, to safeguard public health and meet Illinois' regulations for businesses. We handle all necessary permits and inspections.
Backflow Testing and Certification in Naperville
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 on the spot with genuine parts. We submit passing results so you avoid compliance letters or service interruption.
Double Check Valve Assembly (DCVA) Installation in Naperville
The double check valve assembly, or DCVA, is a common backflow preventer for low-hazard applications where the consequences of backflow are not severe. In Naperville, DCVAs are frequently installed on fire sprinkler systems or irrigation lines. Our certified plumbers carefully 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.
Reduced Pressure Zone (RPZ) Device Installation in Naperville, IL
For high-hazard applications in Naperville, IL 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. HVM 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.
Irrigation Backflow Preventer Installation in Naperville
Landscape irrigation is the most common reason homeowners need a backflow device. Fertilizer, herbicides and stagnant water in sprinkler and drip lines can be siphoned into your drinking water if pressure drops. We install pressure vacuum breakers or double check assemblies based on local requirements and the design of your system. Above-ground installs are set at least 12 inches above the highest sprinkler head when a PVB is used.
