Frozen Pipes

When the temperature is extremely cold, the water in your pipes may freeze, which can make the pipes burst.

To Help Prevent Frozen Pipes

  • Check for open windows, air vents, and drafts near water pipes.
  • Seal leaks in the basement foundation where cold air may enter. Stuff holes with insulation. A tiny opening my cause an exposed pipe to freeze.
  • Allow a slow trickle of water to flow through faucets connected to water pipes that run through unheated spaces.
  • Open cabinet doors under sinks during cold spells to allow warm air to circulate around the pipes.
  • Putting foam insulation on a copper water pipe.Insulate pipes in unheated spaces like garages, basements, and crawl spaces.

Be Ready in Case You Have a Pipe Freeze

  • Find your water shut off valves and know how to shut off water if you do have a pipe burst.
  • Get a water alarm to put in your basement or other area where a water leak would not be immediately noticed.

What to Do About Frozen Pipes

  • If a pipe bursts, shut off the water promptly to minimize damage.
  • If your pipes freeze, use a hair dryer to thaw the lines safely. Thawing will not be fast, but it will be safe.
  • Never use an open flame to thaw pipes [that's how my Grandma's house burned down - Webmaster]

When pipes are frozen, there is often water available in at least one faucet. If there is no water coming through any of your taps, there may be a problem in your service outside.
