External check valve assembly for Helix Pond Skimmer. In the instance that the power shuts off to your home and you do not have a check valve on your pond; there is a large possibility that your pond is going to flood. There is a lot of water in the lines above your pump leading to your waterfall body. Having an external check valve will prevent this backflow from happening. Call 909-794-5217 for more questions
