When testing a spill resistant vacuum breaker you use the bleed
valve arrangement to compensate for a leaking #1 shut off valve
and you are testing the check valve where is the bleed valve
arrangement connected? - ANSWER-On the test cock
When testing a spill resistant vacuum breaker and the air inlet
fails you may proceed in the following manner: - ANSWER-fail the
air inlet valve and fail the assembly
When testing a spill resistant vacuum breaker you have opened
the high side needle valve one quarter turn but the air inlet does
not open. you open the bleed valve arrangement and a small
amount of water discharges from the testcock and stops. Your
gauge is still indicating 0.0 at the low end of the scale. Your
assessment of the malfunction is: - ANSWER-The #2 shut off
valve is leaking with parallel installation with back pressure

You are testing the check valve of a spill resistant vacuum
breaker and the reading on your test kit is 0.3 psid. Your
assessment of the failure is: - ANSWER-Dirty or damaged check
disc
The maximum pressure loss through a SVB assembly is: -
ANSWER-Not more than 10.0 psi
When testing a reduced pressure principle backflow prevention
assembly, you have closed the #2 shut off valve, opened the high
side control needle valve approximately one turn and opened the
low side control needle valve no more than one quarter turn. The
indicator on the test kit does not continue to move to the low end
of the scale to open the differential pressure relief valve. What is
the most probable cause indicated by the test kit - ANSWER-The
#2 shut off valve is leaking with demand downstream
When testing the air inlet of a pressure vacuum breaker you have
closed the #2 shut off valve, have closed the #1 shut off valve and
located your test kit at the appropriate elevation. You open the
high side bleed needle valve no more than one quarter turn, the
indicator on the test kit stays at the high end of the scale with

water continuously discharging from the high side bleed needle
valve. How do you proceed? - ANSWER-Close the high side
needle valve. Open the #1 test cock fully to compensate for a
leaking #1 shut off valve.
When testing the #1 check valve of a double check valve
assembly testcock #3 is opened and the value on the test kit is an
indicated 0.4 psi, how do you proceed? - ANSWER-Note the
value for the #1 check valve on the test form, continue to the #2
check valve, fail the #1 check valve and fail the assembly.
When installing a backflow prevention assembly there are going
to be changes in the water system that may cause serious
problems in the water system. Which of the following problems
would be caused by creating a closed water system? - ANSWER-
Thermal expansion
When testing reduced pressure principle backflow prevention
assembly you have prepared to test the #2 check valve. As you
move water behind the #2 check valve the indicator on your test
kit begins to move to the high side of the scale. What is the

correct procedure to follow in this situation? - ANSWER-Close the
#2 testcock
When testing the #1 check valve of a double check valve
assembly you opened the bleed valve arrangement to record a
value of 0.6 how do you proceed? - ANSWER-Stop the test until
repairs are made to the #1 check valve.
When the bleed valve arrangement is needed to compensate for
a leaking shut off valve when testing a pressure vacuum breaker,
where is the bleed valve arrangement located? - ANSWER-On
the #1 test cock
The differential pressure gauge is the correct test kit to use when
testing atmospheric vacuum breaker? True or False? - ANSWER-
False.... Cannot test AVB
One foot of elevation is equal to what psi? - ANSWER-.433 psi
