discharge side of the piping system that is greater than that of the supply side
of the system.
Quiz :Backsiphonage - √Answer :A form of backflow due to negative or sub-
atmospheric pressure within water system.
Quiz :Backflow prevention methods - √Answer :Any approved device which
prevents an undesirable reversal of flow of water by the introduction of air,
check valves, or a combination of both.
Quiz :Backflow prevention devices - √Answer :Air Gap
Atmospheric Vacuum Breaker (AVB)
