    vacuum breakers

    Just to clarify, not to break spheres. A vacuum breaker is used to protect potable water from backflow. A vacuum relief valve is (NJ Code) required if any hot water outlets are BELOW the water heating source. This is to prevent forming a vacuum in the vessel and having the reduced pressure cause the water to flash to steam. Steam can make a very loud sound when it explodes.
