In Atlanta, Georgia the average low temperatures usually only reach the freezing point of water in January and February. Atlanta’s average low is 31 degrees in January and 34 in February.
The water in your pipes will freeze when its temperature falls below 32 degrees. So, pipes that are in unheated areas of the house (like the attic or basement), pipes that run along exterior walls which do not have adequate insulation, and pipes that run outside of the house (like the spigot for a garden hose) are all particularly vulnerable to freezing when the weather gets cold.
When water freezes it expands. So, if a pipe is completely full of liquid water and it freezes, the ice will take up more space than the water did. This puts pressure on the walls of the pipe and results in a crack. The real fun begins when the ice melts and the water begin to pour out all over the inside of your house. Unfortunately, this happens to most people in the middle of the night, because that’s when temperatures are at their lowest.
By taking a few simple precautions, you can save yourself the mess, money and aggravation frozen pipes cause.
During Cold Weather, Take Preventive Action
So, while frozen pipes are not a huge problem here in Atlanta, it will feel like a huge problem if it happens to you. By taking some simple precautions you can avoid being an exception to the norm.
