Main highlights

•Notes and Suggestions: On one hand, the fountain is suitable for Above and In-ground Pools. On the other hand, if you want a strong powerful spray it will be dependent on your pool pump! 0.75HP sand pump injection distance up to 10 meters, 0.1HP/1000 gallons / 80W ordinary filter pump (HP = 80/745.7) injection distance of about 4 meters, 0.02HP/530 gallons / 15W ordinary filter pump can not be sprayed at all. It is recommended that you use a filter pump of at least 0.2hp and above.
•Easy to Installation: Put together in minutes. Turn off your pool pump, unscrew and remove the jet nozzle, attach the fountain, turn pump back on, and adjust the water flow and direction to your liking. Included a detailed step manual, Let us know if you need help with assembly and installation, SUMMERBUDDY team will be there to help you as soon as possible.
•Upgrade Dual Spray Pool Fountain： Attach directly to pump return outlet, the riser pipe is barely noticeable. The newly upgraded dual-spray fountain is more interesting than the single-spray one, with more water spraying, and a longer spraying distance. Sprinklers successfully cooled the water temp 6-10 degrees. Does real good at keeping the water cool.
•Controllable Waterfall Direction and Height: Simply rotate on riser pipe to adjust the PARALLEL and CROSS water spray. (Ensure nozzles toward the pool when changing direction). Control of water pressure by adjusting the pressure regulator to fit your unique pool (Tips: the smaller the opening, the higher the waterfall).
•Enjoy and Relax in Your Pool: Imagine! 1 When you wake up and watch your new private waterfall in the pool. Listen to the soothing sound as you sit by the pool, grab a cup of wine, and enjoy leisure time with friends and family.
