Keeping pipes from bursting

The overnight temperature dipped below freezing Tuesday in many parts of Georgia. The coldest weather occurred in the counties already affected by the level four drought. As a result, people want to know which is worse, dripping faucets or busted pipes.

“We’ve noticed a definite increase in the number of calls related to the age-old practice of letting water faucets drip to prevent pipes from freezing,” said Drought Response Unified Command member Charley English, who also heads the Georgia Emergency Management Agency.

Pipes that freeze most frequently are those that are exposed to severe cold, like outdoor hose bibs, swimming pool supply lines, water sprinkler lines and water supply pipes in unheated interior areas like basements and crawl spaces, attics, garages or kitchen cabinets. Also, pipes that run against exterior walls that have little or no insulation are also subject to freezing. Pipe freezing is a particular problem here in Georgia with our usually warm climate because pipes often run through un-insulated or under-insulated attics or crawl spaces.

There are many ways to prevent pipes from freezing and conserve water at the same time. When the temperature drops below freezing:

• A trickle of hot and cold water might be all it takes to keep your pipes from freezing. Let warm water drip overnight, preferably from a faucet on an outside wall. However, this water should be captured in a container and used for other household purposes. It should not be wasted by allowing it to go down the drain. Also, remember to close all faucets when the temperature rises above freezing. Do not allow faucet to drip unnecessarily.

• Open cabinet doors to allow heat to get to un-insulated pipes under sinks and appliances near exterior walls.
The best ways to prevent frozen pipes before the onset of cold weather are to:

• Insulate pipes in your home’s crawl spaces and attic. These exposed pipes are most susceptible to freezing. Remember — the more insulation you use, the better protected your pipes will be.

• Heat tape or thermostatically-controlled heat cables can be used to wrap pipes. Be sure to use products approved by an independent testing organization, such as Underwriters Laboratories Inc., and only for the use intended (exterior or interior). Closely follow all manufacturers' installation and operation instructions.

• Seal leaks that allow cold air inside near where pipes are located. Look for air leaks around electrical wiring, dryer vents and pipes. Use caulk or insulation to keep the cold out and the heat in. With severe cold, even a tiny opening can let in enough cold air to cause a pipe to freeze.
