During testing of a double check valve assembly, what does it mean if water continues to discharge after the bleed valve is opened?

• A. The testing is complete
• B. The #1 shut off valve is leaking
• C. Water pressure is too high
• D. The test kit is malfunctioning

Answer: (B)

When testing a double check valve assembly, if water continues to discharge after the bleed valve is opened, it indicates that there is an issue with the assembly, specifically related to the shut-off valve. The double check valve assembly is designed to prevent backflow, and both shut-off valves must function correctly to contain the water within the system. If the first shut-off valve is leaking, it will not maintain a proper seal, causing water to continue to discharge even after the bleed valve is activated. This scenario suggests that there is a failure in achieving a full closure of the valve, which is crucial for the integrity of the backflow prevention system. Therefore, the presence of a steady flow of water is a direct indicator of potential malfunction regarding the first shut-off valve. This outcome emphasizes the importance of inspecting and ensuring that all components of the double check valve assembly are operating properly to maintain an effective backflow prevention mechanism.
