Sample 1Sample 2Sample 3
Reduced pressure backflow assembly. (RPBA) means an approved assembly consisting of two independently operating check valves, spring loaded to the closed position, separated by a spring loaded differential pressure relief valve loaded to the open position, an installed as a unit with and between two resilient seated shutoff valves and having suitable connections for testing. The assembly must operate to maintain the pressure in the zone between the two check valves, less than the pressure on the public water system side of the device. At cessation of normal flow, the pressure between the check valve must be less than the supply pressure. In case of leakage of either check valve, the differential relief valve must operate to maintain the reduced pressure by discharging to the atmosphere. When the inlet pressure drops below two (2) pounds per square inch (13.8 kPa) the relief valve must open to the atmosphere thereby providing an atmospheric zone between the two check valves. (Ord. 1349 §1(part), 2003: Ord. 1190 §3(part), 1996).

Reduced pressure backflow assembly. (RPBA) means an assembly incorporating two check valves and an automatically operating differential relief valve, located between the two shutoff valves, and equipped with necessary appurtenances for testing. This assembly may be used for non-health and health-hazard applications.
