I'm from far up north and we never worried about anything like that unless we were more than 5-10 degrees below freezing for more than 72 hours in a row. Otherwise, you're wasting your time worrying about it. Water in pipes doesn't freeze very fast at all when it's 25 degrees, would take 3 days at 25 degrees for mostly unexposed pipes to freeze at that rate which would likely never happen in TV.
