What is required for the connection between the pool drain and the sanitary sewer?

The requirement that involves having a properly located cleanout for the connection between the pool drain and the sanitary sewer is primarily about ensuring that the drainage system is accessible for maintenance and inspection. A cleanout allows for the easy removal of blockages that may occur in the pipe, facilitating the upkeep of the entire drainage system and preventing overflow or backups within the sanitary sewer.

Establishing a cleanout is critical for system integrity, as it helps maintain proper waste flows and enables the sanitation authority to monitor and manage the drainage effectively. This requirement is often outlined in plumbing codes and regulations to ensure safety and hygiene standards are upheld in public and private swimming pool operations.

The other options, while they might seem plausible, do not address the pressing need for maintenance accessibility directly related to the sanitary sewer connection. The focus on having a cleanout underscores the importance of creating systems that prevent long-term problems and ensure quick solutions in case of clogs or failures in the drainage setup.
