ASSE (Plumbing) 1032-2004(R2011)

The devices covered by this standard are those with functional capabilities for preventing back pressure backflow in water supply lines, and which can operate under continuous or intermittent pressure conditions. These devices consist of two independently acting primary check valves, internally force loaded to a normally closed position, in a common casing or valve body. Devices may have a supplementary check valve downstream of the primary downstream check valve. Where it is incorporated in the design, it shall be held open by suitable means or removed for all performance tests where noted.
