I'm in my first full year as a pool owner and for the life of me , I can not get the basket in front of the pump to stay full of water.I have to unscrew the lid to get it to fill with water , then tighten it back up .after turning the pump on , after about 3 seconds, the basket empties again. I know this cant be good for the pump so I turn it off. I.m very dissatisfied with the company who sold it to me, no how to demos or anything. could anyone on here please help?
