A one-inch opening makes fountain pump connectivity easy, and plastic construction ensures durability while minimizing maintenance. The Lava fountain nozzle adds a unique visual dimension to any pond or lake, artificial or natural, and serves to enhance the surrounding landscape. The nozzle produces a light and modern spray and presents a bell-shaped water wall with an arcing display. Add bubbles to produce a single column of water for a more modern effect. The first step in designing your fountain is to determine what kind of spray column you prefer. The height of the spray--and the type and amount of nozzles--will determine the size of the pump. The choice of nozzle also determines the amount and intensity of light needed. The lava fountain nozzle adds a peaceful tranquility to any outdoor or indoor setting. Avoid setting up the Lava fountain in a space that is frequently impacted by winds as it might alter the water pattern.
