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.
