When the cold weather hits, pipes can freeze, causing thousands of dollars of damage. Your best bet is preventing frozen pipes in the first place. Here are some tips from the American Red Cross and plumbing experts on preventing – and treating – frozen pipes:
Preventing Frozen Pipes
Before the onset of cold weather, prevent freezing of these water supply lines and pipes by following these recommendations:
- Drain water from sprinkler supply lines following manufacturer’s or installer’s directions.
- Remove, drain, and store hoses used outdoors.
- Check around the home for other areas where water supply lines are located in unheated areas. Look in the basement, crawl space, attic, garage, and under kitchen and bathroom cabinets. Both hot and cold water pipes in these areas should be insulated.
- Consider installing specific products made to insulate water pipes like a “pipe sleeve” or installing UL-listed “heat tape,” “heat cable,” or similar materials on exposed water pipes.
- Newspaper can provide some degree of insulation and protection to exposed pipes – even ¼” of newspaper can provide significant protection in areas that usually do not have frequent or prolonged temperatures below freezing.
During Cold Weather, Take Preventative Action
- Keep garage doors closed if there are water supply lines in the garage.
- Open kitchen and bathroom cabinet doors to allow warmer air to circulate around the plumbing. Be sure to move any harmful cleaners and household chemicals up out of the reach of children.
- When the weather is very cold outside, let the water drip from the cold and hot water faucets served by exposed pipes. This relieves water pressure that would normally cause a pip to burst. Even the slowest drip will help relieve pressure!
- If you will be going away during cold weather, leave the heat on in your home, set to a temperature no lower than 55° F.
To Thaw Frozen Pipes
- If you turn on a faucet and only a trickle comes out, suspect a frozen pipe. Likely places for frozen pipes include 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 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 by wrapping pipes with towels soaked in hot water. Do not use a blowtorch, kerosene or propane heater, charcoal stove, or other open flame device.
- 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.
