What should you do if water continues to discharge from the sight tube while testing the #2 check valve?

• A. Close the bleed valve arrangement and open the #2 testcock
• B. Terminate the test immediately
• C. Adjust the elevation of the test kit
• D. Lower the test kit and record the reading

Answer: (A)

When testing a backflow prevention device, the sight tube is used to observe the water flow and pressure conditions of the check valves during the test. If water continues to discharge from the sight tube while testing the #2 check valve, it indicates that there might be an issue with the valve holding pressure or sealing properly. Closing the bleed valve arrangement and opening the #2 testcock is the appropriate action in this scenario, as it helps to isolate the test section and allows for a proper assessment of the valve's performance. This procedure can reduce the potential for backflow issues while enabling the tester to examine the #2 check valve’s function without interference from extraneous water flow. It ensures that the testing process remains controlled, providing clearer readings on the condition of the check valve. Alternative actions, such as terminating the test immediately, adjusting the elevation of the test kit, or lowering the test kit to record readings, do not address the immediate concern of evaluating the #2 check valve under the current testing conditions. Instead, they might lead to incomplete or inaccurate assessments of the backflow prevention assembly's functionality. Proper handling of the bleed valve and testcock allows for a more effective troubleshooting and ensures the integrity of the backflow assembly is determined accurately.
