What device is indicated for protecting the potable water supply on a chicken farm that injects chemicals into the water?

• A. Reduced Pressure Principle (RP)
• B. Atmospheric Vacuum Breaker
• C. Double Check
• D. Pressure Vacuum Breaker

Answer: (A)

A chemical-injection setup creates a cross-connection that could contamination the potable water if backflow occurs. In this scenario you want a backflow preventer that stops all backflow, including both back-siphonage and backpressure, because toxic or hazardous substances are involved. The Reduced Pressure Principle backflow preventer is designed for exactly that level of protection. It has two checks and a relief port that maintains a reduced pressure between them; if any backward flow tries to occur, the relief valve opens to vent to the atmosphere, preventing contaminants from entering the water supply. This makes it the safest and most reliable choice for protecting potable water on a farm where chemicals are injected into the water. Other devices either protect only against back-siphonage or are intended for less hazardous cross-connections, and they don’t provide the same level of protection for a chemical-injection setup.
