How do I thaw frozen pipes?

Contacting a licensed professional is the safest and most reliable way to address frozen pipes. However, if you attempt this on your own, the key is gradually warming and thawing the pipe with safety as a priority (no open flames and no flammable materials around the pipe). The American Red Cross offers additional useful information.

Finally, a Louisville Water tip: If you find yourself dealing with a frozen water pipe, shut off the water in your home by turning off the main water shutoff valve. Here's a video to help you find it: main shutoff valve.
