Thawing Frozen PipesFrom the Red Cross:
To Thaw Frozen Pipes
If you turn on a faucet and only a trickle comes out, suspect a frozen pipe. Locate the suspected frozen area of the water pipe. Likely places include pipes running against exterior walls or where your water service enters your home through the foundation.
- Keep the faucet open. As you treat the frozen pipe and the frozen area begins to melt, water will begin to flow through the frozen area. Running water through the pipe will help melt more ice in the pipe.
- Apply heat to the section of pipe using an electric heating pad wrapped around the pipe, an electric hair dryer, a portable space heater (kept away
from flammable materials) or wrapping pipes with towels soaked in hot water.
- Do not use a blowtorch, kerosene or propane heater, charcoal stove or other open flame device. A blowtorch can make water in a frozen pipe boil and cause the pipe to explode. All open flames in homes present a serious fire danger, as well as a severe risk of exposure to lethal carbon monoxide.
- Apply heat until full water pressure is restored. If you are unable to locate the frozen area, if the frozen area is not accessible or if you can not thaw the pipe, call a licensed plumber.
- Check all other faucets in your home to find out if you have additional frozen pipes. If one pipe freezes, others may freeze, too.
- Consider relocating exposed pipes to provide increased protection from freezing. Pipes can be relocated by a professional if the home is remodeled.
- Add foam insulation wrap directly to exposed pipes to maintain higher temperatures. Even a couple of degrees can make a difference. Ask at your local hardware or home fix-it store.
- Add insulation to attics, basements and crawl spaces. Insulation will maintain higher temperatures in these areas.
