______________________ is the minimum discharge pipe size from a sump or receiving tank for a sewage pump system?

The minimum discharge pipe size from a sump or receiving tank for a sewage pump system is specified to ensure efficient and effective movement of sewage without causing blockages or excessive pressure in the system. A two-inch discharge pipe is commonly required because it provides a larger diameter that facilitates the proper flow of sewage, minimizing the risk of clogs and allowing the pump to operate at optimal performance.

Using a two-inch discharge pipe ensures that the sewage can be transported over longer distances and at a steady rate, reducing the likelihood that solids will settle and cause backflow or other issues. In sewage systems, maintaining adequate flow is crucial because it helps prevent backups and maintains the overall health of the plumbing infrastructure. A smaller diameter pipe, such as half an inch, would significantly increase the risk of blockages and hinder the performance of the pump.

The reference to "Minimum Per Manufacturer" suggests that specific pump manufacturers might have varying requirements based on their equipment design. However, the standard practice generally adheres to the two-inch minimum to ensure compatibility with the hydraulic parameters involved in sewage transportation. Thus, the two-inch size is a widely accepted minimum in plumbing codes to promote both efficiency and reliability in sewage systems.
