When a backflow device leaks continuously from its relief port or fails its annual inspection, prompt repair prevents water waste, pressure loss, and county non-compliance penalties.

Different plumbing hazards require specific backflow assembly designs. Our DPOR-certified specialists are qualified to service all code-approved devices:
| Device Type | Primary Application | Hazard Level |
|---|---|---|
| Reduced Pressure Zone (RPZ) | Commercial Buildings, Boilers, High-Risk Systems | High Hazard (Health Hazard) |
| Double Check Valve Assembly (DCV) | Indoor Plumbing, Low-Hazard Fire Lines | Low Hazard (Non-Health) |
| Pressure Vacuum Breaker (PVB) | Residential Lawn Irrigation, Landscape Sprinklers | High Hazard (Outdoor Backsiphonage) |
| Atmospheric Vacuum Breaker (AVB) | Hose Bibbs, Point-of-Use Supply Connections | Low to Medium Hazard |
Offers maximum mechanical protection against backsiphonage and backpressure. RPZs feature two independent check valves separated by an intermediate differential relief valve, making them mandatory for commercial facilities, boilers, and high-hazard plumbing systems.
Consists of two spring-loaded check valves in series. DCVs are typically installed indoors or in subterranean vaults for low-hazard non-health risks.
