Customer has waterfall in the backyard. She was concerned that it might freeze from the water source. After inspection, I found the water source is not on, and we cannot find where it comes from or if it’s even hooked up It is recommended to unplug the pump for the waterfall during the winter time so the pump cannot freeze up And in the spring/summertime, just fill the water feature with a water hose like you have in the past then plug in the pump for the waterfall
