F.W.&P.C.O.A. FLORIDA BACKFLOW
PREVENTION ASSEMBLY TESTER
CERTIFICATION COURSE
Air Gap - Correct Answers -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 device and the flood level rim of the receptacle.
Who Can Approve Backflow Prevention Assemblies - Correct Answers -The Foundation
for Cross-Connection Control and Hydraulic Research at The University of Southern
California
Define Atmospheric Pressure - Correct Answers -The Pressure exerted by the weight of
the atmosphere.
As the elevation above see level increases the atmospheric pressure.... - Correct
Answers -Decreases
What is the weight of the atmosphere at sea level - Correct Answers -14.7 PSI
Atmospheric Vacuum Breaker (AVB) Prevents - Correct Answers -Backsiphonage
Define Backflow - Correct Answers -A reverse flow condition, created by a difference in
water pressure, which causes water to flow back into the distribution pipes of a potable
water supply from any source or sources other than an intended source.
Backflow can occur under what two conditions - Correct Answers -Backsiphonage and
backpressure conditions
Backflow Prevention Assembly - Correct Answers -Any mechanical assembly, method,
or means that would prohibit the backflow of water or any other substance into the
potable water supply.
The reference point for installing an AVB device at least 6" higher then the highest
downstream outlet the device serves is know as the: - Correct Answers -Critical Level
Line
, Which backflow prevention assembly is the minimum level of protection required for
non-health hazards with backpressure and backsiphonage conditions - Correct Answers
-Double check valve assembly
What equipment is used to test a reduced pressure principle assembly? - Correct
Answers -Differential Gauge
Define Backpressure - Correct Answers -A condition in which the pressure in the
downstream plumbing system is greater then the supply pressure in the potable
distribution system.
Backsiphonage - Correct Answers -The reversal of flow within a system that is caused
by negative pressure in the supply piping.
How high is a Barometric Loop? - Correct Answers -35FT in height
In a total vacuum will not rise higher then? - Correct Answers -33.9 Feet at sea level
Define Closed System - Correct Answers -Prevents any water that has passed through
the line from backflowing and re-entering the potable water system
Define Containment (Policy) - Correct Answers -To confine potential contamination
caused by a cross-connection within the facility where it arises by installing a backflow
prevention assembly at the meter or service connection when no meter is used.
Continuous Pressure - Correct Answers -Water used for 12 hours or more within a 24
hour period.
Define Critical line level - Correct Answers -a reference line representing the level of the
check valve seat within a backsiphonage control unit. it is used to establish the Hight of
the unit above the highest outlet or flood level rim.
Define Cross-Connection - Correct Answers -Any arrangement of pipes, fittings, fixture,
or devices that connects a non-potable system to a potable water system through which
backflow could occur (an unprotected connection)
Degree of hazard - Correct Answers -The danger posed by a particular substance or set
of circumstances.
Degree of hazard is separated into what two categories - Correct Answers -Low Degree
of Hazard and High Degree of Hazard
Define Low degree of Hazard - Correct Answers -One that does not affect health but
may be aesthetically objectionable.
Potable water that may be yellow in appearance.
