BACKFLOW PREVENTION ASSEMBLY TESTER TRAINING EXAM
QUESTIONS WITH COMPLETE SOLUTIONS VERIFIED 2024/2025
Salmonellosis
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.
Check valve
Overflow level
The maximum height that water or liquid will rise in a receptacle before it flows over the
rim.
Backflow
A hydraulic condition, caused by a difference in pressures, in which non-potable water
or other fluids flow into a potable water system.
RPBP
A shortened name for a reduced pressure backflow preventer
Air Gap
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
,Any arrangements of pipes, fittings, or devices that indirectly connects a potable water
supply to a non-potable source
Dysentery
A disease (sometime waterborne) caused by pathogenic microorganisms and
characterized by severe diarrhea with passage of mucus and blood
Backsiphonage
A backflow condition in which the pressure in the distribution system is less than
atmospheric pressure (subatmospheric)
Hose bib
A faucet to which a hose may be attached
Carrier
A human or animal that carries germs and can pass them to another person without
getting the disease himself.
Reduced pressure zone backflow preventer
A mechanical device consisting of two independnetly operating, spring-loaded check
valves with a reduced pressure zone between check valves.
Auxiliary supply
Any water source or system, other than the potable water supply, that may be available
in the building or premesis.
Actual Cross Connection
Any arrangement of pipes, fittings, that connects a potable water supply directly to a
non-potable source at all times.
Hepatitis
, An inflammation of the liver caused by a pathogenic virus. Symptoms are jaundice,
general weakness, nausea, and the presence of dark urine.
Feed water
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
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
In cross-connection control, any pipe arrangement that passes water around a
protective device, causing it to be ineffective.
Gastroenteritis
An intestinal disease caused by pathogenic microorganisms, which involves
inflammation of the stomach and intestines. Symptoms are diarrhea, pain, and nausea.
Back pressure
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
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
Any arrangement of pipes, fitting, fixtures, or devices that connects a non potable
system to a potable water system
