jerryjay11, thanks for the suggestion but I don't think it is ice.. The lowest it has been here for the last week was around 45. It was mid 60's yesterday when I was trying this. We have probably had no more than 20 hours total of freezing. I only used antifreeze this year, because I knew I would be out of state and couldn't turn on the heat the few nights temps would drop below freezing. I am in far South GA. Less than 60 miles from FL line.
For the rest, I will try again... ensuring opening several faucets.
