Product Details

Zurn Industries 3-350ADABG

The 3'' 350ADABG Double Check Detector Backflow Assembly, with grooved end butterfly valves with integral supervisory switches, protects against both back siphonage and backpressure in low health hazard, fire protection applications. Featuring a metered bypass system, the 350ADA efficiently detects leaks and any unauthorized water use. Its single access cover reduces down time and added costs associated with maintenance and repairs. Lighter in weight than the 350DA Model, the 350ADA features a short lay-length for compact, versatile installation in horizontal or vertical positions.
