Hi all, I have noticed for quite sometime that I have air returning into the pool jets and the spa return as well, the basket on the pump is virtually full, but a little air can be seen at the top, not filled to the top like it use to be. Anyway, is there any trouble shooting procedure or tips to help identify where the air is being sucked in at? I have an 18 x 36 pool with spa, a DE filter fnsp 60, and a sta rite 2 hp pump, with a heat pump as well. There are a lot of lines out around the filter and pump, and I"m not sure where to begin. Thanks Craig
