COLD WEATHER AND YOUR WATER SYSTEM

Why Pipe Freezing is a Problem

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. Pipes that run against exterior walls that have little or no insulation are also subject to freezing.

Preventing Frozen Pipes

Before the onset of cold weather, prevent freezing of these water supply lines and pipes by following these recommendations:

• Remove, drain, and store hoses used outdoors. Close inside valves supplying outdoor hose bibs. Open the outside hose bibs to allow water to drain. 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.
During Cold Weather, Take Preventative Action

• 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 cold water drip from the faucet served by exposed pipes. Running water through the pipe – even at a trickle – helps prevent pipes from freezing.

• 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

• Before attempting to thaw a frozen pipe, inspect the pipe for damage. Water expands as it freezes, which can rupture the frozen section of pipe.

• 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, or a portable space heater (kept away from flammable materials). Do not use a blowtorch, kerosene or propane heater, 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, if you find damage to the frozen area, or if you cannot 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.
