Keep pipes from freezing

January 18, 2012
The Daily News

Each winter, some 250,000 homes sustain damage when water pipes freeze and burst.

Recovering from frozen pipes is not as simple as calling a plumber, reports State Farm Insurance officials.

An eighth-inch crack in a pipe can spew up to 250 gallons of water a day. Both plastic (PVC) and copper pipes can burst.

By taking a few simple precautions, homeowners can save the mess, money and aggravation that frozen pipes cause.

Before the cold hits

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.

Disconnect garden hoses and, if practical, use an indoor valve to shut off and drain water from pipes leading to outside faucets. This reduces the chance of freezing in the short span of pipe just inside the house.

When the mercury drops

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.

Open cabinet doors to allow heat to get to uninsulated pipes under sinks and appliances near exterior walls.

Before you go away

Set the thermostat in your house no lower than 55 degrees.

Ask a friend or neighbor to check your house daily to make sure it's warm enough to prevent freezing or shut off and drain the water system.

Be aware that if you have a fire protection sprinkler system in your house, it will be deactivated when you shut off the water.

If your pipes freeze

Don't take chances. If you turn on your faucets and nothing comes out, leave the faucets turned on and call a plumber. If you detect that your water pipes have frozen and burst, turn off the water at the main shut-off valve in the house; leave the water faucets turned on.

Make sure everyone in your family knows where the water shut-off valve is and how to open and close it.

Never try to thaw a pipe with a torch or other open flame.

Water damage is preferable to burning down your house. You may be able to thaw a frozen pipe with the warm air from a hair dryer.

Start by warming the pipe as close to the faucet as possible, working toward the coldest section of pipe.

Do not use electrical appliances in areas of standing water because you could be electrocuted.

Cold weather tips

Be extremely careful if you use a wood stove, fireplace or space heater in your home.

Always keep a multipurpose, dry chemical fire extinguisher near the area you are heating.

Do not burn paper in your fireplace or wood stove and do not leak flue gas indoors. If you are using an indoor gas heater, be sure it is located in a well-ventilated space and only use the type of fuel recommended by the manufacturer.

Regardless of the type of heating device you are using, be sure that it is up to date and meets all safety standards.

Toxic fumes, such as carbon monoxide, from old or faulty heaters can cause unconsciousness or death from lack of oxygen.
