I was wondering if anyone could help me out here. We had our pool put in last summer, and had a couple of weeks of swim time without a problem. Recently our skimmer has been acting up. It seems like the float valve is closing when the pump comes on, giving us no suction to the skimmer. When i hook the robot/vacuum up to the line it works so I know there is suction there. I know it's something simple. Thanks in advance.
