When testing a pressure vacuum breaker, what indicates that the pressure has been successfully established?

• A. The bleed valve arrangement shows no discharge
• B. Water continues to discharge from the test kit
• C. The indicator shows an acceptable value
• D. The #1 shut off valve is not leaking

Answer: (C)

The indication that pressure has been successfully established in a pressure vacuum breaker is when the indicator shows an acceptable value. This value reflects the maintained pressure necessary for the system to function properly, ensuring that the backflow prevention mechanism is operational. The indicator is a critical tool during testing, providing immediate feedback on the pressure within the system and confirming that it is within the designed parameters. In contrast, if the bleed valve arrangement shows no discharge, it does not directly confirm that pressure is set correctly; it merely suggests that there isn’t an issue with the valve itself. Similarly, water continuing to discharge from the test kit may indicate a malfunction or failure, rather than a successful establishment of pressure. Lastly, while ensuring that the shut-off valve is not leaking is important for overall system integrity, it does not provide direct evidence of successful pressure establishment like the indicator does. Thus, the indicator's reading is essential for assessing the system's readiness and functionality.
