The building drain is sized based on the drainage fixture unit load connected to the drain. The DFU load is a measure of the probable discharge into the drainage system from several types of plumbing fixtures. It takes into account factors such as the type of fixture, the expected frequency of use, and the flow rate. Therefore, the drain size is determined by the maximum DFU load that can be handled by the drainage system, which determines the minimum size of the building drain.
