BACKFLOW PREVENTION ASSEMBLY TESTER
TRAINING EXAM STUDY GUIDE
Salmonellosis - 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. - Answers :Check valve
Overflow level - Answers :The maximum height that water or liquid will rise in a
receptacle before it flows over the rim.
Backflow - 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 - Answers :A shortened name for a reduced pressure backflow preventer
Air Gap - 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
Auxiliary supply - Answers :Any water source or system, other than the potable water
supply, that may be available in the building or premesis.
Actual Cross Connection - Answers :Any arrangement of pipes, fittings, that connects a
potable water supply directly to a non-potable source at all times.
Hepatitis - 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 - 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 - 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 - Answers :In cross-connection control, any pipe arrangement that passes water
around a protective device, causing it to be ineffective.
Gastroenteritis - Answers :An intestinal disease caused by pathogenic microorganisms,
which involves inflammation of the stomach and intestines. Symptoms are diarrhea,
pain, and nausea.
, Back pressure - 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 - 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 - Answers :Any arrangement of pipes, fitting, fixtures, or devices that
connects a non potable system to a potable water system
Atmospheric vacuum breaker - Answers :A mechanical device consisting of a float
check valve and an air inlet port designed to prevent backsiphonage
Double Check Valve Assembly - Answers :A testable mechanical device consiting of
two independently operating, spring-loaded check valves
Potable - Answers :Water that is safe for human consumption
Backflow - Answers :The reversal of the normal direction of flow
Backpressure - Answers :An elevation of pressure in the downstream piping system
above the supply pressure
Backsiphonage - Answers :Reduction in system pressure which causes a sub
atmospheric pressure to exist at a site in the water system
Cross-connection - Answers :A link between potable and non-potable sources
potential cross connection - Answers :Any arrangements of pipes, fittings, or devices
that indirectly connects a potable water supply to a non-potable source
Dysentery - Answers :A disease (sometime waterborne) caused by pathogenic
microorganisms and characterized by severe diarrhea with passage of mucus and blood
Backsiphonage - Answers :A backflow condition in which the pressure in the distribution
system is less than atmospheric pressure (subatmospheric)
Hose bib - Answers :A faucet to which a hose may be attached
Carrier - 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 - Answers :A mechanical device consisting
of two independnetly operating, spring-loaded check valves with a reduced pressure
zone between check valves.
