In the typical installation sequence, which step comes after laying the pipe and before surface restoration?

• A. Backfilling
• B. Testing
• C. Installing bypass
• D. Installing line markers

Answer: (B)

Testing the line to confirm its integrity is the key step after laying the pipe and before surface restoration. By applying pressure to the installed system, you verify there are no leaks and that joints or welds will hold under normal operating conditions. This early check catches faults while the trench is still open, making repairs easier and cheaper than after backfilling and restoring the surface. If issues are found, they can be addressed before you proceed with backfilling and surface restoration, ensuring the installation is safe and code-compliant. (A temporary bypass may be used to maintain service during construction, but the standard sequence places the test here, before backfill and surface restoration.)
