Hello all, I am wondering if you can give me some advice on the proper way to blow my lines. I am new to the closing process but want to learn to do it myself as it is getting expensive. As you can see in the picture the circle at the bottom right is my saltwater cell which will be unhooked in stored for the winter. Am I able to shop vac blow those lines both ways to blow out to the skimmer and return? If so, how would I get antifreeze into those pipes? The circle in the top left, do I need to unhook those for any reason? The skimmer is an aqua genie.
