When should an inspection be ordered for an external sewer line?

Ordering an inspection for an external sewer line at the point when the pipe is on 6 inches of sand and before backfill is crucial for several reasons.

Firstly, this timing ensures that the installation is reviewed before it is covered up. Inspecting the pipe at this stage allows for verification of proper alignment, support, and integrity, which is essential to prevent future issues that may arise due to improper installation.

Additionally, checking the pipe before backfill provides an opportunity to examine the drainage system and ensure that it meets all required codes and standards. This includes confirming the appropriate slope and the correct joints and connections, which are vital for proper function and preventing blockages.

Once backfill occurs, access to the pipe will be significantly limited, making it challenging to address any issues that may not have been identified during the initial installation. Thus, ordering the inspection at this specific moment is a best practice in construction aimed at ensuring the long-term reliability and functionality of the sewer line.
