Winterizing Your Fountain Bowl

It is recommended to completely drain the Fountain Bowl and store it in a frost-free location. Remove the standpipe to drain for winterization. If you are unable to store inside, drain the bowl and basin and cover with tight fitting cover. Prevent water, snow, and ice from accumulating on top of the cover, causing it to sag into the bowl and basin. Note: Fountain Bowls set up as Biological Filters must also be winterized properly.
