When you lose inlet pressure to a pressure vacuum breaker with a dynamic flow downstream of
the pressure vacuum, breaker assembly, the following occurs:
The air inlet opens and the check valve closes
Pressure vacuum breaker assemblies are the correct protection for the following type(s) of
degree of hazard:
High hazard with backsiphonage only
The correct elevation of a pressure vacuum assembly is:
12'' above the highest point of usage and downstream piping
When testing a pressure vacuum breaker and the air inlet fails to open you may proceed in the
following manner:
1|Page
,Fail the air inlet and continue to test the check valve
When testing a pressure vacuum breaker, you have opened the high side needle valve one
quarter turn but the air inlet does not open. You open the #1 test cock and a small amount of
water discharges from the test cock. Your gauge is still indicating at the high end of the scale.
your assessment of the malfunction is:
The #2 shut off valve is leaking with a parallel installation.
You are testing the check valve of a pressure vacuum breaker and the reading on your test kit is
0.3 psid. Your assessment of the failure is
Dirty or damaged check disc
.The maximum allowable pressure loss through a pressure vacuum, breaker assembly is:
not more than 10.0 psi
A local ordinance establishing a cross-connection control program must require that:
A certified tester test the assembly at least once each year and report the test results to the
water authority in a timely manner
An approved air gap used for backflow prevention shall be:
A vertical dimension of at least twice the diameter of the supply pipe and but in no case less
than one inch above the overflow rim
The proper location for backflow prevention assembly for the protection of a service connection
is:
in an above grade, protected and accessible site and before any tees in the service line

, If water is continuously flowing from the relief valve port of a reduced pressure principle
backflow prevention assembly the person testing the assembly could report:
The first check may be fouled; or the relief valve may have malfunctioned; or the second check
is fouled with backpressure on the assembly
Backpressure will cause backflow:
Through an unprotected feed to a closed make-up water tank
The primary responsibility for requiring the testing, maintenance and reporting on service
protection backflow prevention assemblies is normally vested in the :
Water purveyor
In testing a reduced pressure principle backlfow prevention assembly:
The relief valve must be tested first
A water agency or public health agency may require more frequent testing of a backflow
prevention assembly than the maximum time allowed between testing. What is the maximum
legal length of time permitted between tests?
Twelve months
One form of backflow is:
Backsiphonage through a submerged inlet
When a perfect vacuum, at seas level, draws up water into a 40-foot vertical pipe, the pressure
in the pipe above the water surface pipe is:
Zero psia
