Abstract: A P-trap drainage device having a tubular body and a plurality of internal angled vanes which direct water flow in a circular or whirlpool pattern has a short coupling portion having a coupling thereon, and an extension portion dimensioned and configured to fit within standard sizes of plumbing pipes. In use, the device causes vertically flowing water coming from the drain to the P-trap to “swirl”, increasing the efficiency of flow. The shortness of the coupling portion allows easier use of the device in typically cramped conditions.
