This 1/2 inch lead free anti-siphon vacuum breaker prevents the reverse flow of polluted water from entering into the potable water supply due to backsiphonage. It consists of a lead free brass body with polished chrome finish, chemical resistant silicone seat disc, and atmospheric vent to prevent spilling. It has a full size orifice to assure pipe size capacity and maximum flow. It is ideal for low flow, non-continuous hot or cold water health hazard installations such as on laboratory equipment.
