I found it very interesting when the techs reported that the reason so many pipes are breaking is because many of our water pipes are “run” in the attic and many of those are above the insulation! When temperatures dip below freezing for long periods of time the water has a chance to freeze and expand within the pipe causing a joint to fail or the pipe itself to crack. Once the temperatures begin to rise…you have a real water damage mess on your hands!
A few things you can do to help “insulate” your home from this type of water disaster and keep those pipes from breaking is to keep your home at a minimum of 65 degrees, check that all outside faucets are covered (wrap with a towel and secure or purchase covers at your local hardware store) and insulate the pipes in your attic. Letting a faucet drip overnight also keeps the water “moving” in the pipes which makes it harder to freeze.
