Backflow Prevention Assembly Tester Training -
GA
1.What is an actual cross connection?: Any arrangement of pipes,
fittings, or devices that connects a potable water supply directly to a
non-potable source at all times
2.What is an Air Gap?: The unobstructed vertical distance through the
free atmos- phere 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
3.What does AVB stand for?: Atmospheric Vacuum Breaker
4.What is an Atmospheric Vacuum Breaker?: A mechanical device
consisting of a float check valve and an air-inlet port designed to
prevent backsiphonage
5.What is an auxiliary supply?: Any water source or system, other
than the potable water supply, that may be available in the
building or premises
6.What is backflow?: A hydraulic condition, caused by difference in
pressures, in which non-potable water or other fluids flow into a potable
water system
7.What is backpressure?: A backflow condition in which a pump,
elevated tank, boiler, 0r other means results in a downstream pressure
greater than the supply pressure
8.What is backsiphange?: A backflow condition in which the pressure
in the distribution system is less than atmospheric pressure (sub-
atmospheric)
9.What is a bypass?: In cross-connection control, any pipe
arrangement that passes water around a protective device, casing it
to be ineffective
10.What is a carrier?: A human or animal that carries disease germs and
can pass them to another person or animal without getting the disease
itself
11.What is the purpose of a check valve?: To allow flow in only one
direction
12.What is a cross connection?: Any arrangement of pipes, fittings,
fixtures, or devices that connects a non-potable system to a potable
water system
13.What does DCVA stand for?: Double Check Valve Assembly
14.What is a DCVA?: A testable mechanical device consisting of two
independently operating, spring-loaded check valves
15.What is feed water?: Water that is added to a commercial or industrial
system and is subsequently used by the system, such as water that is
