WebConverting DFU (drainage fixture units) of a drainage system to GPM (gallons per minute) is a simple matter of dividing it in half. When determining the necessary capacity of a drainage or sewer system, it is vital to know the flow of material that is going to be traveling … Web20 Sep 2024 · So, for example, the WDC might estimate a peak demand of 20-gpm for that piping, which would require a minimum diameter pipe of 1-inch. By comparison, the old fixture-unit method would derive a peak demand of 30 gpm for the same configuration, requiring a 1 ¼-inch diameter pipe.
