If its any consolation it was 9 degrees here last night. My pool is not winterized and it's uncovered. I have been running my pump 24/7 and the water temp is below 40F. Right now there is 4" of sleet surrounding it. My fountain gets a large icecicle on it that I have to knock off every 24 hours but other than that all seems fine. I was worried sick about the freezing weather but now I know what my plumbing can endure.
