An RPZ, or Reduced Pressure Zone assembly, offers the highest level of protection, suitable for high-hazard cross-connections. A DCVA, or Double Check Valve Assembly, provides moderate protection and is typically used for low to medium hazard situations, like irrigation systems. The choice depends on the application and local code rules.
HNV Plumbing services all major types of backflow preventers, including Reduced Pressure Zone Assemblies, Double Check Valve Assemblies, Pressure Vacuum Breakers, and Atmospheric Vacuum Breakers. We work with popular brands like Watts, Wilkins, Febco, and Conbraco.
Backflow prevention is crucial because of changing water pressures, main breaks and fire flow that can drop pressure suddenly, and the potential for cross-connections from irrigation systems or industrial processes. These factors increase the risk of contaminated water entering the public supply, making a working backflow preventer a must.
Yes. Parts carry the manufacturer warranty and our workmanship is guaranteed. Every repair is retested to confirm it passes before we leave.
No, backflow preventer installation and major repairs should only be performed by a licensed and certified plumber. Improper installation or repair can lead to water contamination, which poses serious health risks and can result in steep fines from local authorities. Special tools and training are required.
Signs of a failing backflow preventer include discolored water, strange odors from your tap, a noticeable drop in water pressure, or visible leaks around the device itself. If you notice any of these, contact a professional plumber immediately to assess the issue.
Water providers may send follow-up notices, charge fees or eventually suspend service. Scheduling early avoids these problems. We can often fit urgent tests in on short notice.
