Preventing pipes from freezing during severe cold weather

MARQUETTE – As the temperature drops, the chances of haing frozen water lines goes up.

The Marquette City Department of Public Works says a ‘let-run’ advisory is currently in effect for about 150 customers. Those with Public Works say the biggest way to combat frozen pipes is prevention.

Scott Cambensy, Director of Public Works for the City of Marquette: “If the pipes are in the ground, it’s the frost penetrating that deep. If it’s in a house, basement or crawl space, or even under a garage- some people have added on a garage and it’s now over their service but it’s not a heated garage- that’s caused problems, too.”

One way to prevent frozen pipes is allowing water to drip from the faucet served by exposed pipes. Running water through the pipe, even at a trickle, can prevent freezing.

Some helpful tips in preventing pipes from freezing include:

  • 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.
  • Add insulation to attics, basements and crawl spaces. Insulation will maintain higher temperatures in these areas.
  • Check around the home for other areas where water supply lines are located in unheated areas. Look in the 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.
  • Consider relocating exposed pipes to provide increased protection from freezing.

A few other helpful tips include:

  • 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.
  • 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.

The American Red Cross also offer some tips on thawing frozen pipes, including: 

  • 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.

Should you experience frozen pipes, you can call the Department of Public Works. That number is (906) 228-0444.
