Everyone's set-up is a little different and does things differently, but how about this:
I have two skimmers, independently plumbed, not hooked in to the main drain.

My pool company has closed my pool 5 years straight. The one thing I've questioned is the first thing they do is run the pump with the main drain valve set to close. They suck one skimmer until the water is just emptying from it, then pour in 1/2 gal antifreeze, then plug it off. They repeat with the other skimmer. They don't pump the line dry or even pump very long after the skimmer is empty. They just pour in a little anti freeze and plug it. I guess they're depending on the antifreeze.

So I'm doing it this year. Should I suck the lines longer, add more antifreeze, of blow them out?

I plan to purchase an air compressor with a 2 gallon accumulator tank. I figure I can set the pressure to what I want and have enough flow. And I also get to use it for some light construction! Do you think this will be sufficient:
