Backflow Prevention Assembly Tester Training -
Questions With Verified Solutions
What is an actual cross connection? Correct Answer - Any
arrangement of pipes, fittings, or devices that connects a potable
water supply directly to a non-potable source at all times
What is an Air Gap? Correct Answer - 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
What does AVB stand for? Correct Answer - Atmospheric
Vacuum Breaker
What is an Atmospheric Vacuum Breaker? Correct Answer - A
mechanical device consisting of a float check valve and an air-inlet
port designed to prevent backsiphonage
What is an auxiliary supply? Correct Answer - Any water
source or system, other than the potable water supply, that may be
available in the building or premises
What is backflow? Correct Answer - A hydraulic condition,
caused by difference in pressures, in which non-potable water or
other fluids flow into a potable water system
What is backpressure? Correct Answer - A backflow condition
in which a pump, elevated tank, boiler, 0r other means results in a
downstream pressure greater than the supply pressure
, What is backsiphange? Correct Answer - A backflow condition
in which the pressure in the distribution system is less than
atmospheric pressure (sub-atmospheric)
What is a bypass? Correct Answer - In cross-connection
control, any pipe arrangement that passes water around a
protective device, casing it to be ineffective
What is the purpose of a check valve? Correct Answer - To
allow flow in only one direction
What is a cross connection? Correct Answer - Any
arrangement of pipes, fittings, fixtures, or devices that connects a
non-potable system to a potable water system
What does DCVA stand for? Correct Answer - Double Check
Valve Assembly
What is a DCVA? Correct Answer - A testable mechanical
device consisting of two independently operating, spring-loaded
check valves
What is an overflow level? Correct Answer - The maximum
height that water or liquid will rise in a receptacle before it flows
over the rim
What is a potable water source? Correct Answer - Water that is
biologically, chemically, and radiologically safe to drink
What is a potential cross connection? Correct Answer - Any
arrangement of pipes, fittings, or devices that indirectly connects a
potable water supply to a non-potable water source
