American Society of Heating and Ventilating Engineers Guide, 1936 SIZING AN UP-FEED RISER When the riser is an up-feed, the opposite condition occurs; that is, there is a drop in pressure as the top of the riser is approached, due to the natural reduction in the gravity pressure, and to this must be added the pipe friction plus that introduced by the pipe fittings, all of which produce an excessive drop when compared to the conditions existing with a downfeed riser.
