Water fountains have pumps that continually cycle the water through the system, keeping it flowing and running smoothly. The fountain itself has minimal maintenance requirements but it does still need some attention once in a while. If you're having trouble with your water fountain perhaps some of these tips will help. Be sure the fountain pump is strong enough for the water flow needs. Smaller indoor fountains need less water pressure than large outdoor fountains. Most fountains come with the right pump when you by them, but if you ever need to replace the pump you want to be sure the gallons per hour (GPH) rating is right for your needs. The easiest thing is to get the same pump type as you had before, but if you've thrown that away, you can go by this basic range: indoor fountains up to 10" high need about 45-65 GPH, outdoor fountains need about 500 GPH for every 3 feet of fountain height.
If your fountain overflows when the pump is off this means you have too much water in there. As the pump is running there's water in the pump and the tubing, but when shut off that water will settle in the basin. If it overflows your overall water volume is too high. Be sure to have enough water to cover the entire pump, but keep it 3/4 to 1" lower than overall basin rim. After setting the correct volume then turn on the pump and check for noise. If the pump is slightly exposed while running add enough water to cover it. This will cut back the noise and should be low enough to prevent run over when the pump is off. Water fountains are beautiful decorative items that can add a new level to your decor, whether indoor or outdoor. If you take care of them properly they should serve you for a long time.
