When we bought the house, there was a stagnant pod with a little stream of water streaming up in the middle. One of my early projects was to clean out the pond and clean the pump. It worked fine for several years until I had to replace it with Pump #2… which went out this winter after about three years. I’m amazed that these little pumps can run continuously under water for years.

Photo of pump #3 that is now installed and circulating the water. Just in time for spring. Note the little slica gell pack. Keeps moisture down. Wouldn’t want a pond pump getting moist.
