T&S Brass B-0970-FE Dual Check Vacuum Breaker with Intermediate Vent

The T&S B-0970-FE atmospheric vacuum breaker is a vital back pressure backflow preventer engineered to safeguard commercial potable water systems from contamination. Frequently installed in commercial kitchens, food service facilities, and laboratory environments, this backflow preventer mounts vertically downstream of shut-off valves and equipment—such as mop sinks, pre-rinse units, chemical proportioners, and hose connections—where a cross-connection could pull non-potable fluids back into the primary supply lines. Operating automatically via atmospheric pressure, its internal disc float drops to introduce air into the pipeline during a loss of supply pressure, effectively breaking the siphon effect before backsiphonage occurs. Incorporating a durable, polished chrome-plated brass body and reliable 3/8-inch NPT connections, the B-0970-FE offers low head loss, full compliance with strict plumbing codes (ASSE 1001 and CSA B64.1.1), and long-lasting durability, making it an essential, high-converting upgrade for contractors seeking reliable health code compliance and reduced operational downtime.
