What is the minimum vertical distance defined as a Branch Interval in plumbing?

The minimum vertical distance defined as a Branch Interval in plumbing is 8 feet (2438 mm). This specific measurement is important as it helps ensure proper ventilation and drainage within plumbing systems. The Branch Interval is the vertical space required to accommodate changes in flow and pressure which contribute to the efficient functioning of the plumbing system.

By adhering to this measurement, plumbers can prevent issues such as backflow or inadequate drainage, which can lead to more significant plumbing problems. Understanding and applying this measurement correctly is essential for maintaining compliance with plumbing codes and ensuring the reliability of plumbing installations.
