Basic Parts and Functions
A water fountain consists of four basic parts: a pool of water, a submersible pump, a power source to run the pump and tubing to carry the water from the bottom to the surface. The fountain may include one or more nozzles to create different spray patterns, as well as one or more basins into which water can flow.
A filter may also be attached to the setup to keep debris out of the pump.
Water Fountain Operation
The submersible pump connects to an electrical outlet equipped with a ground-fault circuit interrupter or to a solar battery, though some smaller pumps may be powered by an internal battery. The pump sits below the surface, drawing in water and forcing it up through the tube and nozzle.
The arc or stream of water falls back into the basin so that the pump can recycle it again and again.
