| Device Type | Primary Application | Hazard Level |
|---|---|---|
| Reduced Pressure Zone (RPZ) | Commercial Facilities, Boilers, Medical, High-Risk Supply | High Hazard (Health Hazard) |
| Double Check Valve Assembly (DCV) | Indoor Plumbing, Low-Hazard Fire Lines, Vaults | 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 Water Connections | Low to Medium Hazard |
