If the indicator valve on a test kit drops to the relief valve opening point while testing a #2 check valve, how should you proceed?

• A. Open the low side bleed needle valve
• B. Close the high side bleed needle valve
• C. Check for leaks in the assembly
• D. Replace the #2 check valve

Answer: (A)

When the indicator valve on a test kit drops to the relief valve opening point while testing a #2 check valve, opening the low side bleed needle valve is the appropriate action. This step allows for equalization of pressure within the system, providing an opportunity to confirm whether the check valve is functioning correctly or if it has failed. Opening the low side bleed needle valve helps to relieve the pressure that may be causing an incorrect reading on the indicator valve. This procedure is essential in determining if the drop in the indicator value is due to genuine backflow or a malfunction in the testing equipment or system pressures. It's important to follow this step before inspecting for leaks or considering replacement of the check valve, as this could lead to unnecessary actions or expenses if the issue is with pressure imbalance rather than a faulty valve. This ensures a methodical approach to troubleshooting and results in more accurate diagnostics.
