I'm closing my in ground pool for the first time. I am worried about draining the pool low enough so that the returns aren't underwater. I have been told I have high ground water, and worry about floating the liner draining the pool that low. Below the skimmer, no problem. Can I still blow out the return lines and keep them empty? I don't have any pictures now but I'll get some. I have two jets in my setps that mix air/water, any special considerations with that? will it likely be a standard 1.5" threaded plug or something else?
Growing up in Dallas TX I don't remember my dad doing anything special in the winter, we definitely never had a cover. It gets colder here in north MS, but not much.
