The correct use of field test procedures is how we ensure that backflow prevention assemblies will provide the necessary protection to the water system. Any mechanical device or assembly can fail and a robust testing program is needed in any quality cross-connection program. The industry may disagree on which test procedure should be used but everyone agrees that testing in necessary. Its time to pick up your pencil and test your knowledge on the proper use of field test procedures.

Spring 2020

There are several different recognized field test procedures which when used correctly by certified testers will provide accurate results on the status of backflow prevention assemblies installed as cross-connection protection.

It is always necessary to use a sight tube when testing an ASSE 1015 Double Check Valve Assembly with the USC 10th Edition Field Test Procedure.

When flushing the test cocks on an ASSE 1013 Reduced Pressure Principle Assembly using either the ASSE of USC Field Test Procedures the first test cock opened is:

When testing the 2nd check valve on an ASSE 1013 Reduced Pressure Principle Assembly using the One Hose Field Test Procedure the check valve is tested:

When testing the air-inlet of an ASSE 1020 Pressure Vacuum Breaker using the ASSE Field Test Procedure pressure is bleed out of the assembly using the:

If a certified backflow tester finds that an ASSE 1013 Reduced Pressure Principle Assembly has failed a field test he is required to leave the assembly shutoff until repairs are made and the valve is retested.

The majority of certified testers in the United States use a _________ Valve Test Kit when testing backflow assemblies.

The Field Test Procedure that fully opens the relief valve on an ASSE 1013 Reduced Pressure Principle Assembly is the:

Using the USC 10th Edition Field Test Procedure on an ASSE 1013 Reduced Pressure Principle Assembly, if the relief valve opens when the 2nd check is initially back pressured, the tester must then:

When testing an ASSE 1056 Spill Resistant Vacuum Breaker Assembly using the _________ Field Test Procedure the Vent Valve Screw is removed completely from the assembly.

When testing assemblies using the USC 10th Edition Field Test Procedure it is required to use a bleed valve arrangement on every assembly type except:

Using the ASSE Field Test Procedure for backflow prevention assemblies with the exception of the ASSE 1056 Spill Resistant Vacuum Breaker Assembly, the first component tested is the:

When using the One Hose or the USC 10th Edition Test Procedure in testing an ASSE 1020 Pressure Vacuum Breaker Assembly the first component tested is the:

Shut off valves on an ASSE 1048 Double Check Detector Assembly shall be:

Which of the following devices or assemblies is not approved for high hazard service?
