What section of the code addresses drainage systems?

The section that addresses drainage systems specifically focuses on the design, installation, and maintenance of drainage systems in plumbing. This includes regulations concerning the removal of wastewater and sewage from buildings and the necessary connections to municipal or on-site sewage treatment systems.

By concentrating on drainage systems, this section ensures that plumbers understand the criteria for proper drainage, including factors like venting, slope, and material specifications, which are essential for preventing blockages, ensuring sanitary conditions, and reducing the risk of backflow.

While other sections may deal with general requirements, water supply, or plumbing fixtures, they do not specifically cover the detailed guidelines needed for effective drainage systems. Therefore, the information under this third section is crucial for anybody involved in plumbing to ensure compliance with safety and regulatory standards.
