What is the recommended distance apart for iron hangers supporting horizontal soil branch piping?

For horizontal soil branch piping, the recommended distance between iron hangers is 1.5 meters. This spacing is crucial to ensure proper support and stability of the piping system. Maintaining the right distance helps prevent sagging or bending of the pipes, which can lead to obstructed flow, increased stress on joints, and potential leaks over time. Properly installed hangers help distribute the weight of the pipes evenly, supporting both the pipes and their contents effectively. Additionally, adhering to this spacing guideline is important for maintaining compliance with plumbing codes and standards, which further ensures the longevity and reliability of the installation.
