Auto Air Vent

An auto air vent, also known as an AAV, a bottle vent, an auto purger or an auto de-aerator, is a mechanical device which has the purpose of automatically releasing air that is trapped within a water system to prevent pressure build up. Usually they will be fitted on the pump, and can also be found at the highest point of an appliance. Auto Air Vents are also used in heating systems and on water heater discharge lines to make sure that trapped air pockets can be relieved before pressure buildup causes damage to the system.
