Preventing frozen pipes: tips from the experts


Depositphotos_9251576_xsIn frigid weather, the the common wood frog adapts by literally putting itself into a deep freeze. In a miracle of biology, these adaptive frogs freeze solid and their hearts stop, but they come back to life with the spring thaw.

While frozen frogs are pretty amazing, frozen pipes are anything but. If you turn on your faucet in the winter and nothing comes out, there’s a good chance you may have frozen pipes, particularly if the weather has been very cold. Frozen pipes can be a costly claim on your homeowners policy, but a few annual maintenance steps can help prevent problems. Even if you didn’t prepare well before the winter and now find yourself in frigid weather pattern, there are steps you can take to protect your pipes. The Red Cross offers excellent tips for preventing frozen pipes as well as tips for how to thaw pipes out should they freeze. Here are a few of their tips during cold weather:

  • 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.

FEMA also has some excellent tips for before, during and after winter storms and extreme cold.
