BACKFLOW PREVENTION ASSEMBLY
TESTER TRAINING QUESTIONS AND
ANSWERS WITH COMPLETE
SOLUTIONS 100% CORRECT RATED A+
Salmonellosis
Answer: A disease caused by pathogenic bacteria, commonly associated with
chicken, which affects the intestinal tract. The primary symptom is severe diarrhea.
A valve designed to open in the direction of normal flow and close with the
reversal of flow.
Answer: Check valve.
Overflow level
Answer: The maximum height that water or liquid will rise in a container before it
begins to overflow the rim.
Backflow
Answer: A hydraulic condition caused by a difference in pressure, in which non-
potable water or other fluids flow into a potable water system.
RPBP
Answer: A shortened term for a reduced pressure backflow preventer.
Air Gap
Answer: In plumbing, the unobstructed vertical distance through the free
atmosphere between the lowest opening of any pipe or outlet supplying water to a
tank, fixture, or container, and the overflow rim of that container.
,potential cross connection -ANSWER✔✔Any arrangements of pipes, fittings, or
devices that indirectly connects a potable water supply to a non-potable source
Dysentery -ANSWER✔✔A disease (sometime waterborne) caused by pathogenic
microorganisms and characterized by severe diarrhea with passage of mucus and
blood
Backsiphonage -ANSWER✔✔A backflow condition in which the pressure in the
distribution system is less than atmospheric pressure (subatmospheric)
Hose bib -ANSWER✔✔A faucet to which a hose may be attached
Carrier -ANSWER✔✔A human or animal that carries germs and can pass them to
another person without getting the disease himself.
Reduced pressure zone backflow preventer -ANSWER✔✔A mechanical device
consisting of two independnetly operating, spring-loaded check valves with a
reduced pressure zone between check valves.
Auxiliary supply -ANSWER✔✔Any water source or system, other than the
potable water supply, that may be available in the building or premesis.
Actual Cross Connection -ANSWER✔✔Any arrangement of pipes, fittings, that
connects a potable water supply directly to a non-potable source at all times.
Hepatitis -ANSWER✔✔An inflammation of the liver caused by a pathogenic
virus. Symptoms are jaundice, general weakness, nausea, and the presence of dark
urine.
, Feed water -ANSWER✔✔Water that is added to a commercial or industrial system
and subsequently used by the system, such as water that is fed to a boiler to
produce steam.
Pressure vacuum breaker -ANSWER✔✔A device designed to prevent
backsiphonsge, consisting of one independently operating spring-loaded check
valve and an independently operating spring-loaded air-inlet valve.
Bypass -ANSWER✔✔In cross-connection control, any pipe arrangement that
passes water around a protective device, causing it to be ineffective.
Gastroenteritis -ANSWER✔✔An intestinal disease caused by pathogenic
microorganisms, which involves inflammation of the stomach and intestines.
Symptoms are diarrhea, pain, and nausea.
Back pressure -ANSWER✔✔A backflow condition in which a pump, elevated
tank, boiler or other means results in a downstream pressure greater than the
supply pressure
Incubation period -ANSWER✔✔The time period that elapses between the time a
person is exposed to some disease and the time that person shows the first sign of
symptom of the disease.
Cross connection -ANSWER✔✔Any arrangement of pipes, fitting, fixtures, or
devices that connects a non potable system to a potable water system
Atmospheric vacuum breaker -ANSWER✔✔A mechanical device consisting of a
float check valve and an air inlet port designed to prevent backsiphonage
