Zurn Industries stainless-steel backflow preventers
Zurn’s 375ASTDAR stainless-steel replacement reduced-pressure detector assembly and 350ASTDAR stainless-steel replacement double-check valve assembly are available in sizes from 2 1/2” to 10”. They are lightweight, corrosion-resistant, easier to install in small spaces and can be used in most existing low-pressure systems. These models incorporate the Zurn Wilkins AR backflow option, ideal for drop-in replacement of an existing assembly. The AR option comprises custom-length, build to order assemblies — available in stainless-steel or ductile-iron bodies — with a turnaround time of 48 hr. within receipt of an order.
