After repairing a leak and re-testing, what is the recommended action?

• A. Re-pressurize and re-test the affected area.
• B. Immediately resume full operation without testing.
• C. Replace the tank.
• D. Seal the tank and halt testing.

Answer: (A)

Verification after a repair hinges on confirming that the fix actually stopped the leak and that the system still holds pressure at the required test level. Re-pressurizing to the test pressure and then re-testing the repaired area ensures the seal can sustain operating conditions and meets the allowable leak rate over the specified duration. If the area holds, you’ve validated the repair and can proceed; if not, further repair is needed and the re-test should be repeated until the leak is eliminated. This approach prevents continuing with an unresolved leak and ensures the tank remains safe and compliant with testing standards.
