What does it indicate when water continues to discharge from the assembly with no decrease in pressure while testing the check valve of a spill resistant vacuum breaker?

• A. The assembly is in proper working order
• B. The #1 shut off valve is leaking
• C. The relief valve is malfunctioning
• D. The second check valve is leaking

Answer: (B)

When water continues to discharge from the assembly with no decrease in pressure while testing the check valve of a spill-resistant vacuum breaker, it indicates that the number one shut-off valve is leaking. In a properly functioning spill-resistant vacuum breaker, one would expect that closing the shut-off valve would stop the flow or significantly reduce the pressure. If there is continuous discharge with sustained pressure, it suggests that the shut-off valve is not sealing correctly, allowing water to escape and resulting in a failure to hold pressure. This scenario highlights the importance of inspecting valves for leaks, as a leaking shut-off valve can compromise the overall functionality and safety of the backflow prevention assembly. Ensuring that all components, particularly shut-off valves, are in good working order is crucial for effective backflow prevention.
