Understanding the Basic Function of Backflow Preventers in Commercial Irrigation
Commercial irrigation systems are vital for sustaining landscapes in public spaces, large estates, and commercial establishments. One of the most crucial components of these irrigation systems is a device known as a backflow preventer. As the name suggests, it helps prevent the reverse flow of water from the system back into the main water supply. This is essential to not only comply with sanitary regulations, but also to protect the public water supply from potential contamination by fertilizers, pesticides, or other chemicals used in irrigation.
Backflow Preventers essentially eliminate the risk of contaminating potable water supplies due to backpressure or back-siphonage. Backpressure occurs when the downstream pressure is more than the supply pressure, whereas back-siphonage happens when negative or reduced pressure exists in the supply line. To give you a better understanding, here’s a breakdown of how these mighty devices work:
- Pressure Vacuum Breaker (PVB): A PVB is installed above the highest point of water usage, and it’s considered highly efficient in sprinkler systems. When the water flow slows down or stops, the valve closes and protects your water from being polluted.
- Double Check Valve: This type contains two check valves assembled sequentially, providing double protection. Mostly used in underground applications, this type is usually installed horizontally.
- Reduced Pressure Principle (RPZ): An RPZ consists of two independently operating check valves with a pressure-monitored chamber in between. Any backflow is ejected out of the device, hence, ensuring complete cleanliness of the water.
Each of these types of backflow preventers has its own advantages and is used based on the kind of irrigation system and the potential degree of contamination hazard. Having a correct and functional backflow preventer installed is the key to a healthy and efficient irrigation system.
