After seeing all the posts about different ways of closing the pool and freezeproofing all the lines, here in Canada ground freezes solid and deep and I question myself what is the true risk of damage to the pool plumbing/skimmer what if I did the bare minimum such as opening removing drains from pumps, filters. How many people on the great site have or heard of people have getting a split pipe or cracked skimmer directly due to frost? Obviously it is not something I will try and one occasion for any of you is still too much, it is more for the peace of mind knowing that the bare minimum is ok and that what most of us do is 'overkill'.
By the way for my main drain instead of trying to do an airlock, I take a 10 foot piece of 3/4 inch foam rope and tape it in a few places to a 10.5 foot fiberglass wire fish (to pull wire through the walls) and push that down the main drain, it beats just trying to push the foam rope down by itself, this way 24 inches was the best I could do.
