When testing a pressure vacuum breaker, what should you do if water continues to discharge from the high side bleed needle valve?

• A. Close the #2 shut off valve
• B. Open the #1 testcock
• C. Open the #1 testcock to compensate for a leaking #1 shut off valve
• D. Reduce the pressure at the test kit

Answer: (C)

When testing a pressure vacuum breaker, if water continues to discharge from the high side bleed needle valve, opening the #1 testcock to compensate for a leaking #1 shut-off valve is the correct action to take. This occurs because if the #1 shut-off valve is not sealing properly, it can cause backpressure that prevents the vacuum breaker from functioning as intended. By opening the #1 testcock, you allow additional pressure relief and can help ensure proper readings during the test. The main goal in this situation is to stabilize the system and accurately assess the pressure condition. By addressing the leaking shut-off valve in this manner, you can help mitigate the issues caused by the leakage and enable a more effective test of the pressure vacuum breaker. This approach is a crucial aspect of troubleshooting and maintaining the integrity of the backflow prevention system.
