So what should you do if your pipes already froze?

Keep the flow going.

Even if your pipes have frozen, you should keep your faucet open and keep a drip flowing. As the frozen area begins to melt, water will flow through the lines, helping the ice melt around the pipe. This also continues to release pressure in the water system and could lessen the chances of a complete rupture.

Apply Heat.

You have plenty of heating methods to choose from to help thaw the frozen pipes. Apply heat to the frozen area by wrapping an electric heating pad around the pipe, blowing hot air on the frozen area with an electric hair dryer or soaking towels in hot water and wrapping them around the pipes. You could also use a portable space heater to warm the underside of the house – if and only if you keep it away from flammable materials and never leave it unattended. Whichever method you choose, you’ll want to continue applying heat until full water pressure is restored.

Call a plumbing professional.

If you’re unable to locate the frozen area or if your heating applications haven’t worked how you’d like them to, call a licensed plumbing professional to help.

Install leakSMART.

After you’ve thawed the pipes, it would be a great time to install leakSMART. This water leak detection system can help by alerting you of a problem and shutting off the water supply in the event of a leak.

There are ways to help prevent frozen pipes so that you don’t come home to a watery disaster. Follow these tips to achieve that peace of mind you crave while you’re away. Or for even more assurance, install a leakSMART system in your home to detect and stop leaks before they start.
