What kinds of testing are typically required for newly installed drainage systems?

The appropriate testing for newly installed drainage systems typically involves pressure testing and flow tests. Pressure testing is crucial for identifying any leaks or weaknesses in the system that could lead to failures after installation. It ensures that the system can withstand the intended operational pressures without leaking or bursting.

Flow tests are equally important as they assess the system's capacity to handle the expected volume of wastewater or stormwater. These tests help confirm that the design specifications are met and the system will function effectively under typical conditions.

Visual inspections alone are generally not sufficient to ensure the integrity and functionality of a new drainage system. While they can highlight obvious issues, they do not provide the rigorous assessment that pressure and flow testing can. Similarly, stating that no testing is required ignores the necessity for verification of the system's performance and safety. Lastly, while regular cleaning and maintenance checks are vital for the long-term health of the drainage system, they do not replace the initial testing requirements that ensure proper installation.
