Performance Requirements for Water Pressure Reducing Valves for Domestic Water Distribution Systems standard by American Society of Sanitary Engineering, 10/01/2009
Positive pressure reduction devices are to be used in building drainage waste and vent (DWV) systems. They are intended to reduce the impact of short duration air pressure transients which arise in DWV networks through use. They are not intended to have any effect on long duration or steady-state offsets in air pressure.
