What must be done when connecting a drainage system to a public sewer system?

When connecting a drainage system to a public sewer system, proper venting is essential to ensure that the drainage system operates effectively and safely. Venting allows air into the plumbing system, which helps to maintain neutral air pressure throughout the system. This processes facilitates the smooth flow of wastewater by preventing siphoning in the traps, which can lead to odors and the potential backup of sewage.

Venting is also crucial for the health and safety of the building's occupants since it allows harmful sewer gases to escape, reducing the risk of exposure to detrimental substances. Proper venting is a critical requirement in plumbing codes to enhance the functionality and safety of the drainage system when interfacing with public sewer systems.

While there are other considerations, such as the materials used in the piping, joining methods, and fitting designs, these are secondary to ensuring that the system is adequately vented to comply with plumbing standards and regulations.
