Maintenance & Winterization


Aerating Fountains require minimal maintenance, to insure years of dependable service we recommend the following:

  • 1

    Once a year: Disconnect unit from power and physically inspect aerator, float and electrical cable.

  • 3

    Every three years: An oil change is suggested to keep your aerator running smoothly.


If temperatures drop BELOW 20° Fahrenheit or -7° Celsius these units should be removed from the water.

NOTE: Units should never be stored upside down.
