That's a great idea. I do put our pool on top of a layer of 1" rigid insulation to help with heat loss, but I think I might be able to make it work. I usually do not have too much water left, maybe a half inch at one end. The drain can usually get most of it and then I use a towel. With no rain and plenty of sun the next few days, I might luck out and be able to let mother nature fully empty it for me!
