The Flower Fountain adds a beautiful visual aesthetic to your pool, as well as serving a much appreciated function. A fountain can cool the temperature of your water as much 5-6 degrees in the right application. This fountain screws into the return of the Splash pools. It will replace the eyeball that is usually in the fitting. Simply unscrew the eyeball and screw the fountain in. You can adjust the amount of water routed through the flower vs bypassing the flower. This will also allow you to control the distance that the flower shoots the water into the air. Every pool should have one!
