Study Pack
• Overflow level. CORRECT ANSWER: The maximum height that water or liquid will rise
in a receptacle before it flows over the rim.
• Backflow. CORRECT 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. CORRECT ANSWER: A shortened name for a reduced pressure backflow
preventer
• Air Gap. CORRECT 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. CORRECT ANSWER: Any arrangements of pipes, fittings,
or devices that indirectly connects a potable water supply to a non-potable source
• Backsiphonage. CORRECT ANSWER: A backflow condition in which the pressure in
the distribution system is less than atmospheric pressure (subatmospheric)
• Hose bib. CORRECT ANSWER: A faucet to which a hose may be attached
• Reduced pressure zone backflow preventer. CORRECT ANSWER: A mechanical
device consisting of two independnetly operating, spring-loaded check valves with a
reduced pressure zone between check valves.
• Auxiliary supply. CORRECT ANSWER: Any water source or system, other than the
potable water supply, that may be available in the building or premesis.
• Actual Cross Connection. CORRECT ANSWER: Any arrangement of pipes, fittings,
that connects a potable water supply directly to a non-potable source at all times.
• Feed water. CORRECT 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. CORRECT 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. CORRECT ANSWER: In cross-connection control, any pipe arrangement that
passes water around a protective device, causing it to be ineffective.
• Back pressure. CORRECT ANSWER: A backflow condition in which a pump, elevated
tank, boiler or other means results in a downstream pressure greater than the supply
pressure
• Cross connection. CORRECT ANSWER: Any arrangement of pipes, fitting, fixtures, or
devices that connects a non potable system to a potable water system
• Atmospheric vacuum breaker. CORRECT ANSWER: A mechanical device consisting
of a float check valve and an air inlet port designed to prevent backsiphonage
• Double Check Valve Assembly. CORRECT ANSWER: A testable mechanical device
consiting of two independently operating, spring-loaded check valves
• Potable. CORRECT ANSWER: Water that is safe for human consumption
• Backflow. CORRECT ANSWER: The reversal of the normal direction of flow
• Backpressure. CORRECT ANSWER: An elevation of pressure in the downstream
piping system above the supply pressure
• Backsiphonage. CORRECT ANSWER: Reduction in system pressure which causes a
sub atmospheric pressure to exist at a site in the water system
• Cross-connection. CORRECT ANSWER: A link between potable and non-potable
sources
• Potable water. CORRECT ANSWER: Chemically, biologically, radiologically safe,
aesthetically pleaseing
• Backflow prevention. CORRECT ANSWER: Installed for containment and isolation
• Containment. CORRECT ANSWER: Service protection (protects mains from property)
• Isolation. CORRECT ANSWER: Internal protection (isolates each internal area).
• Sewage. CORRECT ANSWER: Can be chemical, biological, or both
• Force. CORRECT ANSWER: A vector that tend to produce an acceleration of a body
in the direction of its application
