[[Cooling waterfall] The fountain jets in this pool return to the fresh air from the jet, reducing the water temperature by 5-15 degrees in the hot summer. It brings soothing and relaxing beautiful rain sounds in the yard. No need to connect hose, no additional power supply[Very suitable for pools] It is easy to install to the return port of the booster pump and adapt to most sizes. The sprinkler function of any underground and above-ground pools can be swung into the water when not in use[Adjustable control valve] The most ingenious part is the side valve, which you can open and close to force more water through the fountain or let more water directly into the pool. The water cover and pump power can be adjusted to control the spray height[Rotating Tee] This pond waterfall has a ball joint under the water, so you can keep the direction of the fountain away from the edge of the pool to prevent water from falling outside the pool. The water outlet is stable and easy to use, and will not rotate/bounce or pop up like a flowing one[Fun for children and families] In addition to the cool water spray, the high-quality ABS plastic white tube allows you to paint children with colors and interesting patterns.
