BACKFLOW PREVENTION ASSEMBLY
TESTER TRAINING – GA EXAM
QUESTIONS ANSWERS
What is an actual cross connection? - Correct Answers -Any arrangement of pipes,
fittings, or devices that connects a potable water supply directly to a non-potable source
at all times
What is an Air Gap? - Correct Answers -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
What does AVB stand for? - Correct Answers -Atmospheric Vacuum Breaker
What is an Atmospheric Vacuum Breaker? - Correct Answers -A mechanical device
consisting of a float check valve and an air-inlet port designed to prevent
backsiphonage
What is an auxiliary supply? - Correct Answers -Any water source or system, other than
the potable water supply, that may be available in the building or premises
What is backflow? - Correct Answers -A hydraulic condition, caused by difference in
pressures, in which non-potable water or other fluids flow into a potable water system
What is backpressure? - Correct Answers -A backflow condition in which a pump,
elevated tank, boiler, 0r other means results in a downstream pressure greater than the
supply pressure
What is backsiphange? - Correct Answers -A backflow condition in which the pressure
in the distribution system is less than atmospheric pressure (sub-atmospheric)
What is a bypass? - Correct Answers -In cross-connection control, any pipe
arrangement that passes water around a protective device, casing it to be ineffective
What is a carrier? - Correct Answers -A human or animal that carries disease germs
and can pass them to another person or animal without getting the disease itself
, What is the purpose of a check valve? - Correct Answers -To allow flow in only one
direction
What is a cross connection? - Correct Answers -Any arrangement of pipes, fittings,
fixtures, or devices that connects a non-potable system to a potable water system
What does DCVA stand for? - Correct Answers -Double Check Valve Assembly
What is a DCVA? - Correct Answers -A testable mechanical device consisting of two
independently operating, spring-loaded check valves
What is feed water? - Correct Answers -Water that is added to a commercial or
industrial system and is subsequently used by the system, such as water that is fed to a
boiler to produce steam
What is an incubation period for a disease? - Correct Answers -The time period that
elapses between the time a person is exposed to some disease and the time that
person shows the first sign or symptom of the disease
What is an overflow level? - Correct Answers -The maximum height that water or liquid
will rise in a receptacle before it flows over the rim
What is a potable water source? - Correct Answers -Water that is biologically,
chemically, and radiologically safe to drink
What is a potential cross connection? - Correct Answers -Any arrangement of pipes,
fittings, or devices that indirectly connects a potable water supply to a non-potable water
source
What does PVB stand for? - Correct Answers -Pressure Vacuum Breaker
What is a PVB? - Correct Answers -A device designed to prevent backsiphonage,
consisting of once independently operating spring-loaded check valve and an
independently operating spring-loaded air-inlet valve
What does RPBP stand for? - Correct Answers -Reduced Pressure Backflow Preventer
What does RPZBP stand for? - Correct Answers -Reduced Pressure Zone Backflow
Preventer
What is an RP? - Correct Answers -A mechanical device consisting of two
independently operating, spring-loaded check valves with a reduced pressure zone
between the check valves
Containment - Correct Answers -Protection on the service line - protects the potable
water supply and not the customer
