Backflow Troubleshooting Quiz Latest Update | 2024/2025 | Graded A+ Well field testing the first check valve of a double check valve assembly, water continues to flow from the site tube. How do you proceed? Observe reading on gauge (first step). Open high side of bleed valve (second step). What are acceptable field test readings for a properly operating double check valve assembly? Check valve number 1: 1.0 PSID and above/ check valve number 2: 1.0 P ID and above What are acceptable field test readings for a properly operating pressure vacuum breaker? Air inlet: 1.0 PSID and above/ check valve: 1.0 PSID and above. When testing an RP, upon closing the number 2 shut off valve and the high and low side bleed valves, the gauge reading drops and differential pressure relief valve begins to discharge. How do you proceed? Record the number 1 check valve is leaking and end the test. When testing and SVB, upon closing the number 1 shut off valve the gauge reading starts to decrease. What does this imply? Number 2 shut off valve leaks with demand. Which of the following are acceptable field test readings for a properly operating reduced pressure principal backflow prevention assembly? 1st check valve: 5.9 PSID/ Relief valve: 2.9 PSID/ Second check valve: tight. While field testing a double check valve assembly, what gauge reading would indicate a check valve failure? Less than 1.0 PSID While field testing the air inlet valve of a pressure vacuum breaker, the high side bleed valve is open 1/4 turn in the gauge reading will not drop. What does this imply? Shut off the valve number 1 is leaking. While field testing the air inlet valve of a pressure vacuum breaker, the high side bleed valve is opened 1/4 turn and the gauge reading will not drop. How do you proceed? Close the high side bleed valve, then open the number 1 test cock. While field testing the check valve of a pressure vacuum breaker, water continues to flow from the # 2 test cock . How do you proceed ? Open the bleed off valve until the flow slows to a slight drip. While field testing the check valve of a spill resistant pressure vacuum breaker, water continues to flow from the vent valve. What does this imply? Number 1 shut off valve is leaking. While field testing the differential pressure relief valve of the RP, what gauge reading indicates a failure? Less than 2.0 PSID While field testing the differential pressure relief
