Enjoy the soothing nature of a beautiful luxury, spa like pool water feature and water decor. Quick and easy to install, the Spa and Swimming Pool Waterfall Fountain works with most in-ground pools, depending on fitting size (fits most 1.5-inch threaded return fittings). Spray height and direction is fully and easily adjustable. For better water flow and stronger spray, make sure your filter is clean and backwashed to increase pressure. If there is low pressure it probably means your filter needs to be cleaned or replaced. Easy installation video is included on this page. Please watch for instructions on how to install and adjust spray.
