This 1-1/4 in lead-free double check valve backflow preventer assembly is designed to prevent the backflow of polluted water from entering into the potable water supply due to backsiphonage and or backpressure. Its compact modular design facilitates easy maintenance with a single access cover for in-line repairs. It is ideal for protection in continuous pressure piping applications and at cross-connections identified as non-health hazards and for contaminants at the service line entrance. This assembly consists of a lead-free body construction, union end connections, quarter-turn ball valve shutoffs, top-mounted test cocks, two in-line independent positive seating check modules, captured springs and replaceable check discs and seats.
