BACKFLOW PREVENTION TEST PAPER
QUESTIONS AND SOLUTIONS FULL REVIEW
GUIDE
●● 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
receptacle before it flows over the rim.
●● Backflow
Answer: A hydraulic condition, caused by a difference in pressures, in
which non-potable water or other fluids flow into a potable water
system.
●● RPBP
Answer: A shortened name for a reduced pressure backflow preventer
●● Air Gap
Answer: 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
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
