A complete assembly consists of two internally loaded, independently operating check valves, located between two tightly closing resilient-seated shutoff valves, with four properly placed resilient-seated test cocks (see Sec. 4.3.1.3).

Purpose

The purpose of this standard is to provide the minimum requirements for double check-valve backflow prevention assemblies for potable water applications, including materials, general and detailed design, workmanship, and shipping and delivery.
