ASSE (Plumbing) 1081 – Performance Requirements for Backflow Preventers with Integral Pressure Reducing Boiler Feed Valve and Intermediate Atmospheric Vent Style for Domestic and Light Commercial Water Distribution Systems

ASSE 1081 provides performance standards and testing procedures for pressure reducing boiler feed valves that offer protection of the potable water supply by means of an integral backflow preventer with an intermediate atmospheric vent. Devices covered by this standard are installed in plumbing systems to fill and reduce static boiler pressure under normal conditions, as well as prevent backflow into potable water supply lines when pressures fluctuate.
