I'm totally confused on how to close my pool, first time owner and I can't screw this up with IGP and concrete decking. 4 returns, 1 skimmer, one side drain.
I get blowing out the plumbing but still not sure if I do this with the water above the returns or not. Do you blow out the plumbing with the water level above returns and skimmer? Then comes the anti-freeze in the plumbing. What the heck do you do with the anti-freeze when you open and how do you get it outta there?
I mean do you put positive air pressure on ALL inputs/outputs, seal them up when they are still under water or what? Then once all sealed and dry how do you put anti-freeze in and what do you do with it when opening. I've read so many time but it's still not making sense.
