This 3/4 inch lead free anti-siphon pressure vacuum breaker backflow preventer prevents the reverse flow of polluted water from entering into the potable water supply due to backsiphonage. It is ideal for health hazard continuous pressure applications such as irrigation systems and industrial process water systems where water enters equipment at or below its flood rim.
