When below zero temperatures hit, our local plumbing companies are deluged with calls to fix/replace frozen pipes. Here are some tips to keep your pipes from bursting.
Thawing Frozen Pipes: If you turn on a faucet and only a trickle comes out, suspect a frozen pipe. Keep the faucet open. As you treat the frozen pipe and the frozen area begins to melt, water will begin to flow through the frozen area. Running water through the pipe will help melt ice in the pipe.
Apply heat to the section of pipe using an electric heating pad wrapped around the pipe, an electric hair dryer, or by wrapping pipes with towels soaked in hot water. Apply heat until full water pressure is restored. If you can't locate the frozen area, it is not accessible, or you cannot thaw the pipe, call a licensed plumber. Be sure to check other pipes as well.
Future Protection: Your spring "to do" list should include adding insulation to attics, basements and crawl spaces. Insulation will maintain higher temperatures in these areas.
Your real estate agent can recommend licensed plumbers or building professionals to help you prevent future freeze-ups.
