Do any have that the Air relief valve (ARV) vault contains standing water (see photo #) An ARV vault near [describe location] contained standing water from ground water intrusion or in the pipes or valves. Standing water at the discharge point of the air relief valve could create a potential backflow problem if the system loses pressure and the water is siphoned back into the main.

(See photo #) (see examples listed below) provide a pathway for to enter the drinking water system during backflow events and therefore present a potential public health threat.
