Tips for Homeowners and Indoor Frozen Pipes

January 27, 2003

During periods of very cold weather, we receive many calls from homeowners seeking advice about what to do when their pipes freeze in their homes. Here are some immediate steps to take to alleviate the problem:

1. If your pipes have frozen, immediately locate your main water service valve and be prepared to immediately shut the water off at the first sign of any water leakage (as outdoor temperatures rise, the ice inside the pipe will melt and leaks may then be evident). This valve is generally located inside your home close to where the line comes in from the meter. For instance, if your meter is in your front yard, the service line extends from the meter, into the yard and into the front part of your house. The valve could be in a closet on your main floor or in the basement. It generally will look like a 'wheel' on the valve and, some instances the service valve could have a lever handle.

2. Turn on the closest faucet to the service valve (a trickle will do) to relieve pressure as the ice melts.

3. Use a blow dryer or space heater to thaw a frozen pipe. Place it 4-5 inches away from the pipe and let it blow until it is thawed. Be patient! This can be time consuming – don't even think about using a blowtorch or other open flame! It’s too dangerous!

4. Once thawed, wrap insulation around water pipes to prevent re-freezing. It is also a good idea to wrap insulation around pipes that are exposed to freezing temperatures, such as those in your garage.

5. Also, try leaving cabinet doors under the faucets open so they can get a bit more heat.
