Engineered for Reliable Cross-Connection Control
At its core, the 975XL operates on the reduced pressure principle, a highly effective method for preventing backflow. This principle involves two spring-loaded check valves and a differential pressure relief valve. When backpressure or backsiphonage occurs, the relief valve senses the pressure differential and opens to discharge water, thereby reducing the pressure between the check valves and preventing contaminated water from entering the potable supply. This multi-stage protection mechanism provides a high level of assurance against contamination, making it a trusted component in safeguarding drinking water systems from potential hazards.
