What is the proper procedure to test a newly installed patch for leaks?

• A. Flood the compartment to check for leaks.
• B. Pressure test the patch and inspect seams for leaks.
• C. Only visually inspect the patch.
• D. Ignore leaks unless they worsen.

Answer: (B)

Testing a newly installed patch requires applying the appropriate pressure to the patched area and inspecting the seams for leaks. This approach directly confirms the patch can hold the intended pressure and that every joint around the patch is sealed. A visual check alone won’t reveal small or slow leaks that only show up when the system is under pressure. Flooding the compartment isn’t a controlled leak test and can create unsafe conditions and additional damage. Likewise, relying on appearances and ignoring potential leaks risks further flooding once the system is back in use. When performing the test, follow the specified test pressure, monitor for any pressure drop, and inspect the patch and seams for signs of leakage, using soap solution or other leak-detecting methods as needed.
