Air release and vacuum breaker valves are typically installed at high points in the pipelines for air release, or at the anticipated pipeline vacuum occurrence location. Air release valves vent the accumulated air to the atmosphere and maintain use of the conduit's full-flow area. These are used to release trapped air within the water system. Pockets of air that restrict water flow accumulate at high points in water mains.
