We had our pool up for 13 days everything was fine. Then the inlet valve at our skimmer basket started to rattle and make whiney sounds. We use to burp the filter a couple of times a day and the water would come out after a second or two - now when we bleed it, it takes 30 seconds or more for the water to come out. When it gets bad, water is gushing through the lines and the swg and lots of air bubbles come out of the outlet into the pool. Water is high. We have a big Hayward cartridge filter with a Hayward dual speed pump. What should we do?
