Different Types of Backflow Preventers: Matching Your Commercial Needs
In understanding the various types of backflow preventers, it’s important to discern which one suits your commercial needs. Commercial plumbing necessitates specific types of backflow preventers to ensure water supply safety and quality. Whether you have a commercial kitchen, office building, or an industrial facility, having a correct backflow preventer is essential.
The most common types of backflow preventers are Pressure Vacuum Breaker (PVB), Reduced Pressure Zone (RPZ), and Double Check Assembly (DCA). The PVB is best used for irrigation purposes and is designed to protect against low hazard situations. When there is a sudden drop in water pressure, the PVB will open to allow air in and stop any backflow. The RPZ, on the other hand, provides a maximum level of protection against high hazard situations, appropriate for industrial or chemical plants due to its two independent check valves and pressure differential relief valve. Lastly, the DCA also suits for low hazard situations and offers protection by utilizing two independent check valves.
| Preventer Type | Best for | Protection Level |
|---|---|---|
| PVB | Irrigation | Low Hazard |
| RPZ | Industrial/Chemical Plants | High Hazard |
| DCA | General Use | Low Hazard |
The conditions of your commercial establishment determine which backflow preventer you need. Hence, it’s crucial to be aware of the complying local codes and water supplier requirements. Do take note as well that each of these preventers need regular inspections and maintenance to ensure their efficient function. Matching your commercial needs with the correct backflow preventer not only ensures compliance but also guarantees a safe and clean water supply.
