A plumbing tree is a prefabricated assembly of drain, waste, vent, and supply lines designed to streamline the installation of plumbing systems in buildings. It typically consists of a vertical stack connected to horizontal branches that distribute water and collect wastewater. Plumbing trees are used in both residential and commercial buildings to ensure efficient water distribution and waste removal, meeting building codes and standards. They simplify installation, reduce labor costs, and ensure consistent alignment and flow throughout the system.
