Service & Installation
RPZ Backflow Preventer stands for Reduced Pressure Zone. The device has a series of check valves that control the direction that water can flow, and a pressure chamber that can be monitored for pressure between the valves. RPZ Backflow devices prevent contaminated water or chemicals from flowing back into the drinking water supply if there is a sudden or unexpected change in water pressure. This backflow can be the result of pressure that builds up in a hot water heater or boiler, or reduced pressure on the supply side caused by sudden increased demand (fire hydrant). RPZ backflow preventers ensure that the safety of the public drinking water is maintained
