Comments: Like all check valves, they do tend to fail over time. We ordered two, one still holds, but one does allow some seepage, but it worked perfect for a year before it started to allow some backflow. We just keep it up towards the surface to the siphon breaks right away anyway. As far as other check valves, these seem to be more reliable and hold longer than other similar check valves. They just need services and replaced just as any would in time.
