What is an actual cross connection?
Ans: Any arrangement of pipes, fittings, or devices that connects a potable water supply directly to a
non-potable source at all times
Quiz What is an Air Gap?
Ans: The unobstructed vertical distance through the free atmosphere between the lowest opening from
any pipe or outlet supplying water to a tank, plumbing fixture, or other container, and the overflow rim
of that container
Quiz What does AVB stand for?
Ans: Atmospheric Vacuum Breaker
Quiz What is an Atmospheric Vacuum Breaker?
Ans: A mechanical device consisting of a float check valve and an air-inlet port designed to prevent
backsiphonage
Quiz What is an auxiliary supply?
,Ans: Any water source or system, other than the potable water supply, that may be available in the
building or premises
Quiz What is backflow?
Ans: A hydraulic condition, caused by difference in pressures, in which non-potable water or other
fluids flow into a potable water system
Quiz What is backpressure?
Ans: A backflow condition in which a pump, elevated tank, boiler, 0r other means results in a
downstream pressure greater than the supply pressure
Quiz What is backsiphange?
Ans: A backflow condition in which the pressure in the distribution system is less than atmospheric
pressure (sub-atmospheric)
