BACKFLOW PREVENTION ASSEMBLY TESTER
TRAINING – GA
What is an actual cross connection? - 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? - 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? - Answers :Atmospheric Vacuum Breaker
What is an Atmospheric Vacuum Breaker? - Answers :A mechanical device consisting
of a float check valve and an air-inlet port designed to prevent backsiphonage
What is an auxiliary supply? - Answers :Any water source or system, other than the
potable water supply, that may be available in the building or premises
What is the purpose of a check valve? - Answers :To allow flow in only one direction
What is a cross connection? - 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? - Answers :Double Check Valve Assembly
What is a DCVA? - Answers :A testable mechanical device consisting of two
independently operating, spring-loaded check valves
What is feed water? - 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? - 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? - 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? - Answers :Water that is biologically, chemically, and
radiologically safe to drink
What is a potential cross connection? - 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? - Answers :Pressure Vacuum Breaker
What is a PVB? - 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? - Answers :Reduced Pressure Backflow Preventer
What does RPZBP stand for? - Answers :Reduced Pressure Zone Backflow Preventer
What is backflow? - 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? - 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? - Answers :A backflow condition in which the pressure in the
distribution system is less than atmospheric pressure (sub-atmospheric)
What is a bypass? - Answers :In cross-connection control, any pipe arrangement that
passes water around a protective device, casing it to be ineffective
What is a carrier? - 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 an RP? - Answers :A mechanical device consisting of two independently
operating, spring-loaded check valves with a reduced pressure zone between the check
valves
Containment - Answers :Protection on the service line - protects the potable water
supply and not the customer
Isolation - Answers :Protection on individual sources of hazard - provides internal
protection
Does GA law require containment or isolation? - Answers :Containment
Organism that causes salmonellosis - Answers :Salmonella
Symptom(s) of salmonellosis - Answers :Acute diarrhea and vomiting
Organism that causes bacillary dysentery - Answers :Shigella
Symptom(s) of bacillary dysentery - Answers :Diarrhea
