Humm there is more to winterizing then pouring down the drains. I used to winterized after thanksgiving. Kept the heat on until then.

I know that there is a lot I have to learn and I've been rather overwhelmed with the sudden loss of my mother....that is why I have the appointment in October to have it winterized professionally. I just wanted to know if there was something I could do in the meantime if temps were to drop....but I guess I'm just being over protective of my new toy. :)
