Dealing With Frozen Pipes

There have been several instances across the country of homeowners trying to thaw thier frozen water pipes with a propane torch, only to lose thier homes when the insulation caught fire. One of these instances resulted in the death of an elderly Texas woman. Ladies and gentlemen please don't try that trick.
If the pipe on an exterior wall freezes raise the household heat a few degrees and open a cabinet door to expose the pipe to the warmer inside air. That's the safest measure you can take.
If you must, use a hair dryer to gently warm the pipe or place a lighted lamp near the frozen pipe. Don't abandon electrical items under the sink. Frozen pipes are subject to burst. Electricity and water don't mix.
