The TacoGenie™ provides hot water at your command at the same time it saves water, energy and money. The TacoGenie™ is a small, silent pump that you attach to the hot and cold water lines in the cabinet under the most remote kitchen or bath fixture in the home. When the TacoGenie™ pump is activated, the cool water you normally let run down the drain is recirculated back to the water heater through the cold water line.
