BACKFLOW PREVENTION ASSEMBLY
TESTER TRAINING EXAM
Salmonellosis - Correct Answers -A disease caused by pathogenic bacterica (often
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. - Correct Answers -Check valve
Overflow level - Correct Answers -The maximum height that water or liquid will rise in a
receptacle before it flows over the rim.
Backflow - Correct Answers -A hydraulic condition, caused by a difference in pressures,
in which non-potable water or other fluids flow into a potable water system.
RPBP - Correct Answers -A shortened name for a reduced pressure backflow preventer
Air Gap - Correct Answers -In plumbing, 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
potential cross connection - Correct Answers -Any arrangements of pipes, fittings, or
devices that indirectly connects a potable water supply to a non-potable source
Dysentery - Correct Answers -A disease (sometime waterborne) caused by pathogenic
microorganisms and characterized by severe diarrhea with passage of mucus and blood
Backsiphonage - Correct Answers -A backflow condition in which the pressure in the
distribution system is less than atmospheric pressure (subatmospheric)
Hose bib - Correct Answers -A faucet to which a hose may be attached
Carrier - Correct Answers -A human or animal that carries germs and can pass them to
another person without getting the disease himself.
Reduced pressure zone backflow preventer - Correct Answers -A mechanical device
consisting of two independnetly operating, spring-loaded check valves with a reduced
pressure zone between check valves.
, Auxiliary supply - Correct Answers -Any water source or system, other than the potable
water supply, that may be available in the building or premesis.
Actual Cross Connection - Correct Answers -Any arrangement of pipes, fittings, that
connects a potable water supply directly to a non-potable source at all times.
Hepatitis - Correct Answers -An inflammation of the liver caused by a pathogenic virus.
Symptoms are jaundice, general weakness, nausea, and the presence of dark urine.
Feed water - Correct Answers -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 - Correct Answers -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 - Correct Answers -In cross-connection control, any pipe arrangement that
passes water around a protective device, causing it to be ineffective.
Gastroenteritis - Correct Answers -An intestinal disease caused by pathogenic
microorganisms, which involves inflammation of the stomach and intestines. Symptoms
are diarrhea, pain, and nausea.
Back pressure - Correct Answers -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 - 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 of
symptom of the disease.
Cross connection - Correct Answers -Any arrangement of pipes, fitting, fixtures, or
devices that connects a non potable system to a potable water system
Atmospheric vacuum breaker - Correct Answers -A mechanical device consisting of a
float check valve and an air inlet port designed to prevent backsiphonage
Double Check Valve Assembly - Correct Answers -A testable mechanical device
consiting of two independently operating, spring-loaded check valves
Potable - Correct Answers -Water that is safe for human consumption
Backflow - Correct Answers -The reversal of the normal direction of flow
