ARI Flood Guard Selfoperating Flood Guard for Air Valves ARI Flood Guard device protects potable water systems from external contamination caused by floodwater overflow In cases where contaminated water infiltrates the manhole and enters the pipeline via the air vacuum kinetic discharge outlet the Flood Guard seals at zero pressure guaranteeing a leaktight seal to prevent water from penetrating the air valve It also allows effective air valve intake and discharge flow rates to be maintained Note During flooding when the Flood Guard is sealed the air valve will not intake air under negative pressure vacuum conditions
