This essential guide prepares you for the AWWA Backflow Prevention
Assembly Testing exam. It provides key practice questions and verified
answers covering testing procedures, troubleshooting, and compliance
standards. Master the critical steps and confidently pass your
certification.
When testing a reduced pressure principle backflow
prevention assembly, there is intermittent spitting from the
relief valve. What is the possible cause of the spitting? supply
pressure fluctuations
When testing the air inlet of a pressure vacuum breaker the
hose(s) on the test kit shall be connected in this manner: High
side hose to the #2 testcock
When testing the #1 check valve of a double check valve
assembly you have opened the #3 testcock to the
atmosphere. The water recedes from the sight tube. How do
you proceed? Lower the test kit to the centerline of the
,2|Page
assembly; record the reading as the static pressure drop
across the #1 check valve. Note that the #2 check valve
and the #2 shut off valve are leaking and terminate the
test.
As you move water from the high side of the #1 check valve
to the low side of the #2 check valve of a reduced pressure
principle backflow prevention assembly, the indicator on the
test kit falls to the low end of the scale and the differential
pressure relief valve discharges a continuous stream of water.
How do you proceed? Open the low side bleed needle valve
to re-establish differential pressure above the apparent
differential pressure to give the #2 check a second chance.
When testing a double check valve assembly and the #1
check valve fails you may proceed in the following manner:
Fail the #1 check valve and continue to test the #2 check
valve
The correct procedure to test the #1 check valve of a double
check valve assembly is to: Install the bleed arrangement on
the #2 testcock before purging air from the test kit
As you start to test the air inlet on a pressure vacuum breaker
you close the #2 shut off valve, raise your test kit to the
, 3|Page
appropriate elevation and close the #1 shut off valve. You
open the high side bleed needle valve one quarter turn. Water
continues to discharge from the high side bleed needle valve
and the indicator on your test kit remains at the high side of
the scale. How do you proceed? Open the #1 testcock to
compensate for a leaking #1 shut off valve.
Regarding question #4, after you have opened the low side
bleed needle valve and re-established the differential pressure
above the apparent differential pressure, you close the low
side bleed needle valve. Now you test kit indicates an
acceptable value for the actual differential pressure across the
#1 check valve. How do you proceed? Accept the value as
the actual differential pressure across the #1 check valve
When testing the #2 check valve of a double check valve
assembly you open the #4 testcock. Water continues to
discharge from the sight tube and the bleed valve
arrangement, after you have opened the bleed valve
arrangement completely on the #3 testcock. How do you
proceed? Close the bleed valve arrangement and open the
#2 testcock to compensate for a leaking #1 shut off valve
When testing the #2 check valve of a double check valve
assembly you open the #4 testcock. The water in the sight
tube recedes. How do you proceed? Lower the test kit to
