What should you ensure before making the connection of the building drain to the sewer main?

Ensuring the protection of the pipe before making the connection of the building drain to the sewer main is crucial for several reasons. The pipe must be safeguarded against potential damage from environmental factors, such as soil movement, water, and other elements that could compromise its integrity over time. This protection might include proper bedding materials, encasement, or using corrosion-resistant materials to extend the life of the piping system.

Additionally, safeguarding the pipe helps maintain the efficiency of the drainage system by preventing leaks, ensuring that the system functions correctly and complies with local codes and standards. Without this protection, the connection may suffer from premature failures, resulting in costly repairs and potential health and safety hazards due to sewage leaks.

Other options would address different steps in the installation process but not specifically the essential need for pipe protection as a primary concern prior to making the connection to the sewer main.
