What Are RPZs and Backflow Devices?
RPZ stands for Reduced Pressure Zone. This is a specialized type of backflow prevention device that guards both your water supply and the city’s from backflow. Backflow is a reversal of water flow that can introduce harmful contaminants like chemical waste, fertilizers, sewage, pesticides, and more into clean water supplies.
RPZs specifically are designed with two check valves (similar to a double check valve) plus a failsafe intermediate relief valve. These barriers prevent water from your business from flowing back into the main water supply, reducing the risk of waterborne illness. Most businesses are required to have these devices according to state and local water safety regulations.
