Where should branch connections to the house drain be made for optimal performance?

The optimal performance of branch connections to the house drain is achieved when these connections are made at the upper portion of the pipe. This positioning helps facilitate effective drainage and prevents the risk of sewage gas accumulation. When the branch connection is made higher up, it allows for a smoother flow of wastewater towards the main drain, minimizing the chances of blockages and ensuring that waste moves efficiently by leveraging gravity.

Furthermore, this approach is in line with plumbing codes and best practices, which emphasize maintaining a proper pitch and height for waste drainage systems. Incorporating these standards not only enhances performance but also contributes to the overall durability and reliability of the plumbing system.
