What is the maximum allowable angle for a junction that connects one drain to another?

The maximum allowable angle for a junction that connects one drain to another is 60 degrees. This angle is significant because it helps maintain good flow characteristics and reduces the risk of blockages. Angles that are too sharp can create turbulence within the flow, leading to debris settling and potential clogs. By adhering to the 60-degree maximum, drainage systems can minimize friction and ensure smoother transitions between pipes, allowing waste and water to move more efficiently through the system. This design consideration is critical for maintaining effective drainage performance and reducing the need for future maintenance or repairs. Overall, using a 60-degree junction optimizes drainage without compromising functionality.
