BACKFLOW PREVENTION ASSEMBLY TESTER
TRAINING
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
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.
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
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
Potable water - Answers :Chemically, biologically, radiologically safe, aesthetically
pleaseing
Backflow prevention - Answers :Installed for containment and isolation
Containment - Answers :Service protection (protects mains from property)
Isolation - Answers :Internal protection (isolates each internal area).
Sewage - Answers :Can be chemical, biological, or both
Force - Answers :A vector that tend to produce an acceleration of a body in the direction
of its application
Force - Answers :Provides energy for motion
Weight - Answers :Type of force resulting from gravity
Force - Answers :Measured in lbs
Area - Answers :The extent of a planar region or the surface of a solid measured in
square units
Area - Answers :Measures the surface of an object
Area - Answers :Tells how big something is
Area - Answers :Measures in square inches (in2)
Pressure - Answers :Force applies uniformly across a surface
Pressure - Answers :=force/area
Pressure - Answers :Tells how much weight over how big a surface area
Pressure - Answers :Measured in lbs/in2 (psi)
