Frozen pipes are one of the most common and costly winter plumbing problems for homeowners, especially during cold snaps in the Pacific Northwest. When water freezes, it expands, placing extreme pressure on pipes. This pressure can cause cracks or complete pipe bursts, leading to flooding, water damage, and expensive repairs.
Knowing how to thaw frozen pipes correctly can help you avoid these risks. Using the wrong methods can be just as damaging as leaving the pipes frozen. This guide explains how to thaw frozen pipes safely, what methods to avoid, and when to call a professional like Einstein Pros for help.
Why Frozen Pipes Are Dangerous
Frozen pipes are not just an inconvenience. According to the American Red Cross, pipes often burst after they thaw, when water pressure returns to the weakened pipe wall. This is why careful thawing is essential.
Common areas where pipes freeze include:
- Exterior walls
- Crawl spaces
- Basements
- Attics
- Under sinks near exterior walls
How to Identify a Frozen Pipe
Before thawing, confirm the pipe is actually frozen. Signs include:
- No water or reduced flow from a faucet
- Frost or ice visible on the pipe
- Bulging or cracking in exposed pipes
- Unusual smells coming from drains
If you suspect a frozen pipe, act quickly but cautiously.
Step-by-Step: How to Safely Thaw Frozen Pipes
1. Turn On the Faucet
Open the faucet connected to the frozen pipe. This allows water to flow as the ice melts and relieves pressure buildup. Flowing water also helps melt ice faster.
2. Apply Gentle Heat
Always apply heat gradually, starting closest to the faucet and moving toward the frozen section.
Safe heat sources include:
- Hair dryer
- Heating pad
- Space heater (kept at a safe distance)
- Towels soaked in hot water
The U.S. Department of Energy recommends controlled heat sources to prevent pipe damage.
3. Keep Cabinet Doors Open
For pipes under sinks, open cabinet doors to allow warm air to circulate. This is especially helpful overnight or during extended cold periods.
4. Continue Until Full Water Pressure Returns
Once water is flowing normally, keep the heat source on for several minutes to ensure all ice has melted. Inspect the pipe carefully for leaks or cracks.
Methods You Should Never Use
Improper thawing methods can cause fires, pipe failure, or structural damage. Avoid the following at all costs:
- Open flames (propane torch, blowtorch, candles)
- Charcoal grills or outdoor heaters indoors
- High-powered heat guns
- Extension cords near standing water
The National Fire Protection Association warns that open flames are a leading cause of house fires during winter pipe emergencies.
What to Do If a Pipe Bursts
If a pipe bursts while thawing:
- Shut off the main water supply immediately.
- Turn off electricity in affected areas if water is present.
- Call a licensed plumber right away.
For fast, professional help, contact Einstein Pros. Prompt response can significantly reduce water damage and repair costs.
Preventing Frozen Pipes in the Future
Prevention is always cheaper than repairs. The Environmental Protection Agency recommends the following steps to protect your plumbing system:
- Insulate exposed pipes
- Seal air leaks near plumbing
- Disconnect outdoor hoses
- Allow faucets to drip during extreme cold
- Maintain consistent indoor temperatures
For older homes or properties with crawl spaces, professional pipe insulation and winterization can provide long-term protection.
