To thaw a frozen water pipe, apply direct heat using a hairdryer or space heater on a low setting, keeping the device 6 inches away from the pipe. Wrap the pipe with insulation or heat tape, and let it sit for 15-30 minutes. If the pipe is located in an interior wall, use a hairdryer to target the frozen section while wearing protective gloves. Avoid using open flames or excessive heat to prevent damage. After thawing, slowly run water to check for leaks and restore pressure.

Pipe freezing occurs when temperatures drop below 32°F (0°C), causing water to expand and crack pipes. Thawing methods work by melting ice blockages through localized heat, which prevents pressure buildup. Insulation retains heat, reducing the likelihood of re-freezing. Data from the Insurance Institute for Property Crime (IIPC) shows that frozen pipes account for approximately 25% of winter-related water damage claims in the U.S., costing billions annually. The National Weather Service notes that 40% of pipe bursts happen within 24 hours of thawing, emphasizing the need for careful post-thaw monitoring. A 2021 study by the American Water Works Association found that 68% of households lack proper insulation, increasing vulnerability. Thawing without insulation can exacerbate damage, as ice formation in adjacent sections may cause repeated cracks. Proactive steps like insulating pipes and using smart leak detectors reduce risks by 50%, per a report by the U.S. Department of Energy. Always prioritize safety by avoiding electrical hazards and consulting professionals for severe cases.
