How Water Fountains Work

It’s as simple as this. Pulled by gravity, water flows downhill and, in the process, adapts itself to whatever solid objects it encounters.

Built around this principle, a fountain is an illusion of sorts. It emulates an outdoor environment, including an endless flow of water coming from an unseen source "upstream." Unlike in nature, however, the water which just flowed by goes back upstream and flows by again and again.

Within this self-contained, closed-loop system, the fountain’s water is constantly recirculated by a small, submersible pump hidden "behind the scenes." The pump pulls water from the receiving pool or reservoir, carries it "uphill" (via a tube) to the fountain head, and gravity does the rest - again and again.

The fountain piece is the waterfall, sculpture, or spout from which the water emerges and flows into the reservoir.

Because the water is recirculated, the self-contained fountain doesn’t waste water. The only water lost is through evaporation - which can be beneficial in humidifying the air. Periodically, you simply replenish the water that has evaporated. (Never let the pump run dry or you’ll ruin it.) Use distilled water.
