  • Patent number: 8905625
    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.

  • Patent number: 8322908
    Abstract: A wall mounted swimming pool venturi jet return line designed to increase water flow for better circulation without effecting the pool pump and filter system. Warm surface water is drawn through a venturi, driving warmer water down to the floor of the swimming pool. Water flow is substantially increased through the venturi jet thus improving water flow throughout the swimming pool. This helps prevent algae growth in poor circulating pools. The return line can rotate in a 360 degree angle, thereby providing multiple benefits and effects. A built-in flange with a locking nut holds the return line in the desired position.

  • Patent number: 4963073
    Abstract: A device for use as a convenient, easy-to-use, and inexpensive pump for pumping water is disclosed which uses water pressure from a standard garden hose connected from a tap to the pump apparatus as the motive power to pump between seven and eleven times the volume of the water from the garden hose from a reservoir into a discharge hose which is any of several different standard sizes and which is connected to the pump apparatus. The water from the garden hose flows into the pump through a pump inlet having a reduced diameter venturi, which increases the velocity of the water, into a pumping chamber with the resulting drop in pressure creating a vacuum in the pumping chamber. The vacuum in the pressure chamber draws water from a reservoir the pump is placed in through a reservoir inlet chamber into the pumping chamber in the pump body, and the water exits the pumping chamber through a pump outlet located on the opposite side of the pumping chamber from the pump inlet.
