In water supply systems, water is normally maintained at a significant pressure to enable water to flow from the tap, shower etc.
When pressure fails or is reduced, as may happen if a water main bursts, pipes freeze or there is unexpectedly high demand on the water system, then such reduced pressure in the pipe may allow contaminated water from the ground, from storage or from other sources to be drawn up into the system. Terminology[edit] Points at which a potable water system connects with a non-potable water system, are called cross connections. Backflow means the undesirable reversal of flow of a liquid, gas or solid into the potable water supply — A backflow preventer keeps this from happening.
Atmospheric vacuum breaker. One-Inch Brass Atmospheric Vacuum Breaker mounted on PVC Pipe An Atmospheric Vacuum Breaker (AVB) is a backflow prevention device used in plumbing to prevent backflow of non-potable liquids into the drinking water system.
It is usually constructed of brass and resembles a 90-degree elbow with a hood on its top to allow air to enter the water system if a siphon attempts to form. Inside this elbow is a poppet valve that is held "up" by the water pressure found in the system, closing the air entrance to the device. Hose Tap Vacuum Breaker.
