Question 1

The ASSE 1012 standard governs which piece of equipment commonly used during backflow field testing?

Accepted Answer

Backflow preventer test kits (differential pressure gauges)

Answer

ASSE 1012 establishes performance requirements for backflow preventer field test kits, including accuracy and construction standards.

Question 2

When attaching test kit hoses to test cocks on a DCVA, the tester should open the test cocks:

Accepted Answer

Slowly to allow gradual pressure equalization and protect the gauge

Answer

Slow, controlled opening of test cocks prevents water hammer and sudden pressure spikes that could damage the gauge or produce erroneous readings.

Question 3

A tester's field test kit hoses develop small cracks near the fittings. The correct action is to:

Accepted Answer

Replace the hoses before performing any tests

Answer

Cracked hoses can leak under pressure, causing incorrect differential readings and a safety hazard; they must be replaced.

Question 4

How frequently should a backflow tester's differential pressure gauge be calibrated according to standard practice?

Accepted Answer

At least annually, or whenever accuracy is suspect

Answer

Annual calibration (or more frequently if the gauge is dropped or suspected inaccurate) is the accepted minimum standard for test kit accuracy.

Question 5

During a field test, a tester uses a stopwatch to time a relief valve opening event. This measurement is used to:

Accepted Answer

Determine the differential pressure at which the relief valve first opens (opening point)

Answer

Timing combined with controlled gauge manipulation helps the tester identify the exact differential at which the relief valve cracks open during an RPZ test.
