Type “winterizing list” into the search box above and you will have many threads to read over. I winterize mine twice a year using the lists and recommendations in those posts and it’s easy and straight forward. My only problem is that I leave for Florida too late and return too early, hence the twice a year…but we’re working on that. Good luck.
