Abstract: The high flow water return fitting of the present invention is designed to connect directly to the end of a water return pipe in a swimming pool, spa, or the like. Water return fittings have been available for many years and have the primary purpose of returning filtered water back into a swimming pool, spa, or the like. However, the water return fitting of the present invention does not only return water into the swimming pool, it also substantially increases the water outflow so that a greater area of water in the pool can be circulated or agitated. The present invention has a uniquely curved nozzle with a flat flange. Both the curvature of the nozzle and the flat flange promote the accumulation of water within the nozzle so as to build up pressure that then pushes the water out a small outlet hole at a greater rate than does a conventional water return fitting. The outflow from the nozzle then creates a low pressure condition within a mixing chamber.
