Backflow Preventers

Backflow preventers prevent contamination of the potable water supply due to back-siphonage or backpressure from substances that are health or non-health hazards. To prevent contamination due to back pressure, many health regulatory regimes require an air gap or mechanical backflow prevention assembly between the delivery point of mains water and local storage or use. Where submerged mains inflow is permitted, a backflow prevention assembly is required, which protects the potable water system from contamination hazards. A check valve is a basic form of backflow prevention, but often more complex devices are required as check valves are not considered as reliable when compared to devices with redundancies and reduced pressure zones.
