Hello, I live in NJ and pool is currently 66 degrees. I would like to close myself before we go away for a few days this week. Is it too early? Second, I don't have a multiport so I'm not sure how to direct blowing out the lines. I have a compressor and i think I just attach it to the pump drain but not sure how to blow out returns, skimmer, water fall. Pool has two returns in shallow end, a polaris line, and a skimmer in deep end. Thanks for the help as always.
