Easy Installation: Setup only takes a few minutes. Turn off the pool pump, unscrew and remove the nozzle, plug in the fountain, turn the pump back on, and adjust the water flow and direction as desired. Pool Fountain with Upgraded Dual Sprinklers: Connects directly to the pump return line; the riser tube is almost invisible. The upgraded dual fountain is more attractive than the single fountain, with a larger water jet and a longer spray distance. The sprinklers cool the water by 6-10 degrees. Really helpful in keeping the water cool. Controllable Waterfall Direction and Height: Simply rotate the riser tube to adjust the parallel and intersecting water jets. (Make sure the nozzle is facing the pool when changing direction.) Control the water pressure by adjusting the pressure regulator according to your pool's needs. (Tip: The smaller the opening, the taller the waterfall.) Enjoy and relax poolside. Imagine it! 1. Wake up to the waterfall of your new private pool. Sit poolside, listen
