What is the vertical measurement distance between connections required for branch intervals?

The requirement for vertical measurement distances between connections for branch intervals is effectively defined by building codes and plumbing regulations, particularly in New York City. A distance of 8 feet ensures that there is adequate space for maintenance, accessibility, and overall efficiency in plumbing systems. This standard helps to avoid issues such as water hammer, unnecessary bends in the piping, and access concerns for repairs or modifications. The 8-foot interval also aligns with best practices in the installation and layout of plumbing systems, facilitating proper drainage and flow without obstruction. This specification aids in promoting efficient plumbing operations within both residential and commercial buildings, ensuring compliance with local safety and regulatory standards.
