AUGUSTA, Ga. (WRDW/WAGT) - Research shows the temperature threshold for pipes is right around 20 degrees.

We could reach that low overnight - meaning there's an increased chance of pipes bursting during this cold snap, which can cost $5,000 or more to repair.

Senior Investigative Reporter Liz Owens explains why homes in the South are often more at risk than other houses in the country.

The reason is builders in the south are less likely to install pipes inside a home or in the warm areas of our homes. Meaning there is less insulation, thus less protection from a freeze.

The pipes running through uninsulated areas of our homes are most at risk, like pipes running along the outside of your home or in your garage and attic.

The best way to protect these pipes is to wrap them in insulation and keep doors closed.

Inside your home, you'll want to keep the thermostat set at the same temperature during the day and night. Also, set your temperature to no lower than 55 degrees.

You also want to open kitchen and bathroom cabinet doors to allow warmer air to circulate around the plumbing.

Make sure you let cold water drip from a faucet. Even a trickle helps prevent pipes from freezing.

Turn off the water at the main shutoff valve which is usually at the water meter or main line.

Turn on the faucet - it will help melt ice in the pipe.

Apply heat to the section of the pipe using an electric heating pad wrapped around the pipe.

Finally, call a licensed plumber to make the repair.
