Will be closing the pool next week. Water is balanced. Not a very complicated setup. I have a mesh cover. 2 return lines and 2 skimmers on the opposite side of the returns. I plan on lowering the water 12 to 18 inches below the skimmers. Removing the pump. Using an air compressor to blowout the return lines when I remove the SWG. I will then cap them. Then blowing out the skimmer lines from where I removed the pump. What kind of connector do I need for my pump to be able to blow those lines out?
