This 10 inch lead free FEBCO MasterSeries LF870W Double Check Valve Assembly is specifically designed to prevent the backflow of polluted water from entering into the potable water supply due to backsiphonage and backpressure. It is ideal for protection in continuous pressure piping applications and at cross-connections identified as non-health hazards and for other non-toxic contaminants at the service line entrance.
