Water Pipes and the Cold: Not a Good Combo [AUDIO]

A new cold snap is expected overnight and through Tuesday and it could take a major toll on the water pipes inside your home.

We all rush out to the grocery store for the bread and milk, and then to the hardware store for shovels, and salt when harsh winter weather is predicted.

But maybe we should be getting heat tape and foam rubber pipe sleeves, according to Richard Barnes of New Jersey American Water.

Barnes said the cold can cause those water pipes to freeze or even burst. That’s why they urge you to try and insulate them as best as you can even before the cold winter months arrive.

“It is so important to get these exposed pipes covered up,” Barnes said. “If not, you should at least open the cabinets containing the pipes and let a heat source in.”

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

  • Drain water from swimming pool and water sprinkler supply lines following manufacturer’s or installer’s directions. Do not put antifreeze in these lines unless directed. Antifreeze is environmentally harmful, and is dangerous to humans, pets, wildlife, and landscaping.
  • Remove, drain, and store hoses used outdoors. Close inside valves supplying outdoor hose bibs. Open the outside hose bibs to allow water to drain. Keep the outside valve open so that any water remaining in the pipe can expand without causing the pipe to break.
  • 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 a quarter inch of newspaper can provide significant protection in areas that usually do not have frequent or prolonged temperatures below freezing.

Take Preventive Action During Cold Weather

New Jersey American Water also suggestions that residents take the following preventive measures before the temperatures drop:

  • 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 cold water drip from the faucet served by exposed pipes. Running water through the pipe — even at a trickle — helps prevent pipes from freezing.
  • Keep the thermostat set to the same temperature both during the day and at night. By temporarily suspending the use of lower nighttime temperatures, you may incur a higher heating bill, but you can prevent a much more costly repair job if pipes freeze and burst.
  • 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.
  • 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.
