Performance Requirements for Reduced Pressure Detector Fire Protection Backflow Prevention Assemblies
The purpose of a Reduced Pressure Detector Fire Protection Backflow Prevention Assembly is to keep contaminated water from fire protection systems from flowing back into a potable water distribution system when some abnormality in the system causes the pressure to be temporarily higher in the contaminated part of the system than in the potable water supply piping. These assemblies are designed to detect low rates of flow up to 2.00 GPM (0.13 L/s) caused by leakage or unauthorized use.
