Alaska’s extreme winter temperatures pose a serious threat to homes, and frozen pipes are among the most common and costly problems homeowners face. Frozen pipes can burst, leading to extensive water damage, costly repairs, and major disruptions. The good news is that with proper precautions, Alaskan homeowners can prevent frozen pipes and avoid the headaches that come with them.
Why Do Pipes Freeze?
Pipes freeze when temperatures drop below 32°F (0°C), but they are especially vulnerable in prolonged subzero conditions. Water expands as it freezes, creating immense pressure inside the pipe. If the pressure builds up enough, it can cause the pipe to crack or burst, resulting in significant water damage.
Common areas where pipes are most likely to freeze include:
- Exposed pipes in unheated areas like basements, crawl spaces, attics, and garages.
- Exterior walls where insulation may be insufficient.
- Outdoor plumbing such as garden hoses, sprinkler systems, and outdoor faucets.
How to Prevent Frozen Pipes
1. Insulate Your Pipes
One of the most effective frozen pipe prevention methods is insulating your pipes. Use foam pipe insulation, heat tape, or heat cables on pipes in unheated areas. Pay special attention to pipes in basements, attics, crawl spaces, and along exterior walls. Insulating hot and cold water pipes also helps maintain consistent temperatures.
2. Keep the Heat On
Maintaining a steady indoor temperature is crucial. Set your thermostat to at least 55°F (13°C), even if you’re away from home. Sudden temperature drops can freeze pipes quickly, so keeping your heating system running prevents this risk.
3. Allow Faucets to Drip
During extremely cold nights, let your faucets drip slightly. Running water, even at a trickle, helps prevent pipes from freezing by relieving pressure buildup. This is particularly important for pipes along exterior walls.
4. Open Cabinet Doors
If you have kitchen or bathroom sinks along exterior walls, open the cabinet doors to allow warm air to circulate around the pipes. This simple step can make a big difference in preventing frozen pipes.
5. Seal Air Leaks
Cold air drafts can significantly lower the temperature around your pipes. Seal cracks and openings around doors, windows, and where pipes enter your home. Use caulk or spray foam insulation to keep the cold out and warmth in.
6. Disconnect and Drain Outdoor Hoses
Before the temperatures drop, disconnect garden hoses and shut off outdoor faucets. Drain any remaining water from hose bibs and irrigation systems to prevent ice buildup. If possible, install frost-proof outdoor faucets for extra protection.
7. Install a Smart Thermostat
A smart thermostat can help maintain a consistent indoor temperature and alert you if the temperature drops too low. Some models even allow you to control your home’s heating remotely, which is especially useful if you’re traveling.
8. Use Heat Sources for Extra Protection
For particularly vulnerable pipes, consider using a safe heat source like a space heater or heat lamp in unheated areas. Be sure to follow safety guidelines and keep any heat sources away from flammable materials.
What to Do If Your Pipes Freeze
If you suspect a pipe is frozen, take action quickly to prevent bursting:
- Turn on the faucet – If only a trickle comes out, the pipe is likely frozen. Keep the water running to help thaw the ice inside.
- Apply heat – Use a hairdryer, heating pad, or warm towels to gently thaw the pipe. Never use an open flame or high-heat source, as this can damage the pipe or start a fire.
- Check for leaks – Once the pipe thaws, inspect it for any cracks or leaks. If you find damage, shut off the water supply and call a professional immediately.
- Know when to call a professional – If you can’t locate the frozen section, if the pipe has already burst, or if you’re unable to thaw it safely, seek professional assistance.
