Air Gap - 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 device and the flood level rim of the receptacle.
Who Can Approve Backflow Prevention Assemblies - ANSWER
The Foundation for Cross-Connection Control and Hydraulic
Research at The University of Southern California
Define Atmospheric Pressure - ANSWER The Pressure exerted
by the weight of the atmosphere.
As the elevation above see level increases the atmospheric
pressure.... - ANSWER Decreases
What is the weight of the atmosphere at sea level - ANSWER
14.7 PSI

Atmospheric Vacuum Breaker (AVB) Prevents - ANSWER
Backsiphonage
Define Backflow - ANSWER 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 - ANSWER
Backsiphonage and backpressure conditions
Backflow Prevention Assembly - ANSWER Any mechanical
assembly, method, or means that would prohibit the backflow
of water or any other substance into the potable water supply.
Define Backpressure - ANSWER A condition in which the
pressure in the downstream plumbing system is greater then
the supply pressure in the potable distribution system.
Backsiphonage - ANSWER The reversal of flow within a system
that is caused by negative pressure in the supply piping.

How high is a Barometric Loop? - ANSWER 35FT in height
In a total vacuum will not rise higher then? - ANSWER 33.9 Feet
at sea level
Define Closed System - ANSWER Prevents any water that has
passed through the line from backflowing and re-entering the
potable water system
Define Containment (Policy) - ANSWER 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 - ANSWER Water used for 12 hours or
more within a 24 hour period.
Define Critical line level - ANSWER 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.
