I have a blower design for air scouring purposes with pipeline to a gravity filter. I need an inverted "pea-trap" on the line to go above the hydraulic grade line of the filters water level (to create an air gap). The pipeline also has a double wafer check-valve and butterfly valve, but failures can happen and there may be some leakage. What can I do to prevent siphoning of water back to the blower when the blower is turned off and valves do not function properly?
