BAT Backflow Assembly Field Testing Procedures 3

Question 1

After completing a backflow assembly field test, the tester's required actions include:

Accepted Answer

Restore the assembly to full service and submit a completed test report

Answer

After testing, the tester must return the assembly to normal operating position (open shutoffs, close test cocks) and provide a completed test report documenting all results.

Question 2

How frequently must a differential pressure gauge used for backflow field testing be calibrated?

Accepted Answer

Annually or per the manufacturer's recommendation

Answer

Test gauges must be calibrated annually or per manufacturer guidelines to ensure readings are accurate and meet regulatory requirements for certified testing.

Question 3

A Spill-Resistant Vacuum Breaker (SVB) differs from a standard Pressure Vacuum Breaker (PVB) primarily because the SVB:

Accepted Answer

Is designed to withstand backpressure without spilling

Answer

The SVB (ASSE 1056) is designed so that backpressure conditions do not cause it to spill, whereas a standard PVB cannot be installed where it may be subjected to backpressure.

Question 4

What is the correct method to verify a test cock is open before attaching test equipment?

Accepted Answer

Confirm the handle is oriented parallel (inline) with the valve body

Answer

On a test cock, a handle parallel to the body indicates the open position; a handle perpendicular to the body indicates the closed position.

Question 5

When a field test report documents a failed backflow prevention assembly, who must be notified?

Accepted Answer

The local water purveyor or authority having jurisdiction (AHJ)

Answer

Failures must be reported to the water purveyor or AHJ so they can require repair or replacement to protect the public water supply.
