What is the minimum size for the ejector system run length compared to the pump discharge outlet?

The minimum size for the ejector system run length should be at least the same size as the pump discharge outlet to ensure proper flow and functionality. This requirement stems from the need to minimize friction loss and maintain adequate flow velocity within the system. If the run length were smaller than the pump discharge outlet, it could lead to increased turbulence, potential clogs, and reduced efficiency of the ejector system. Therefore, matching the size of the run to the pump discharge outlet allows for more efficient transportation of wastewater and prevents backflow or blockages, thus optimizing the performance of the ejector system. The design criteria emphasize that for effective operation and to meet building codes, maintaining this minimum size is critical.
