The Watts 1/2" Lead-Free Bronze Spill-Resistant Anti-Siphon Vacuum Breaker Backflow Preventer is engineered to prevent the backflow of polluted water from entering into the potable water supply due to back-siphonage and backpressure on indoor point-of-use applications. This advanced backflow preventer integrates a thermoplastic check and float assembly valve, stainless steel springs, and tee handles to ensure reliable operation. In addition, the molded diaphragm effectively separates the air inlet from the potable water supply, preventing spillage and maintaining system integrity.
Constructed from high-quality, lead-free bronze, this backflow preventer promises exceptional durability and longevity. Its internal polymer coating further enhances efficiency and reliability, making it a dependable choice for critical water supply systems. The preventer operates efficiently within a wide pressure range, with a minimum operating pressure of 8 psi (55.2 kPa) and a maximum pressure of 150 psi (10.3 bar), accommodating various water system requirements and ensuring consistent performance under diverse conditions.
The spill-resistant design of this backflow preventer makes it particularly versatile for indoor use, especially in health hazard applications where contamination prevention is paramount. It is ideally suited for deployment on machines and equipment within general plumbing systems, offering a reliable solution for maintaining the purity and safety of potable water supplies.
Separation of the water supply from the air inlet is accomplished by means of a diaphragm seal. This feature protects against any spillage during start-up or operation.
