Key Takeaways
- During a power outage, heating systems fail and indoor temperatures can drop rapidly below freezing. Insulating vulnerable areas such as basements and exterior walls will minimize risk.
- Under cold enough temperatures, water expands as it freezes, creating considerable pressure on the pipes, particularly on insulated or otherwise unprotected pipes. The best protection comes from proactively insulating pipes—especially avoidable ones—with foam or heat tape.
- Seal gaps around windows and doors, avoid drastic changes to your indoor temperature, have your heating systems professionally serviced to help them operate at peak efficiency.
- If you allow water to drip from your faucets during a power outage, you can prevent plumbing disasters. Keep cabinet doors open to allow warm air to circulate, and insulate your pipes with blankets for added protection.
- If frozen pipes do occur, thaw them safely with a hairdryer or heat gun, beginning at the faucet end. After the pipe has thawed, monitor it for leaks and call in a professional if there is extensive damage or a pipe has burst.
- For long-term protection, consider installing pipe heating cables. Besides taking the action to upgrade to frost-resistant pipes, investing in a backup power source will further improve your protection against frozen pipes.
To avoid frozen pipes during a Minnesota power outage, the key is keeping water moving and protecting pipes from cold air. Keeping a cold stream of water running from multiple faucets throughout your home can help prevent freezing by keeping water in motion.
Insulating exposed pipes with foam sleeves or heat tape adds an extra layer of protection. This is of particular importance in unheated spaces like basements or crawl spaces.
Opening cabinet doors under sinks lets warmer air circulate around pipes. Sealing drafts around windows, doors, or where pipes come through exterior walls will help keep indoor temperatures from fluctuating.
If you’re able to, having portable heaters set up in key areas can help keep you warm. Taking these precautions long before a storm or power outage comes helps keep your pipes protected during extreme weather and outages.
Why Pipes Freeze During Power Outages
Whether you’re in the depths of a Minnesota winter or preparing for the next crisis, knowledge is power. The freezing temperatures, fused with the immediate loss of heat that comes when the power goes out, produce a perfect storm of danger for plumbing systems.
Pipes in vulnerable locations such as basements, crawlspaces, and exterior walls are at the highest risk.
How cold temperatures affect pipes
This is a problem because when water freezes, it expands, putting extreme pressure on the interior of pipes. This expansion can result in the pipe material cracking or bursting, often worse if the pipes are uninsulated.
Copper pipes, while more resilient at first, can fail after extended periods of freezing temperatures. Conversely, while plastic pipes are generally more flexible and thus better able to accommodate movement, they are susceptible to damage during extreme events.
Temperature fluctuations make things even worse, as thawing and re-freezing alternately cause pipes to expand and contract, eventually compromising their structural integrity.
As you might imagine, uninsulated pipes are especially vulnerable. Water warmed by contact with the surrounding earth might remain above freezing, but stagnant water within pipes is still vulnerable to freezing.
This is what occurs when temperatures fall below 40°F. Without regular use or insulation, the likelihood increases immensely.
Why power outages increase the risk
Power outages worsen the issue since many heating systems cease to operate, causing indoor temperatures to quickly drop to dangerous levels. During these power outages, a quick drop in temperature makes it much more likely that water will freeze in the pipes.
If an outage is hours or even days long, pipes are subjected to freezing conditions for a longer duration. This greatly increases the risk of valuable damage.
In fact, outages are most common during extreme storms. This is especially problematic since residents might not be around to watch the water or shut it off to prevent damage.
This delay in intervention creates the danger of pipes freezing without distinction, increasing the risk of a burst and subsequent water damage. When power outages coincide with below-freezing temperatures, it poses a double whammy to fragile home plumbing infrastructure.
Common areas where pipes freeze
Some areas of the house are more susceptible to frozen pipes. These include:
- Basements: Often unheated and exposed to colder temperatures.
- Attics: Poorly insulated areas can lead to freezing risks.
- Pipes running along outer walls face direct exposure to cold.
- Crawlspaces: Limited insulation makes these areas especially vulnerable.
Outdoor faucets, or sillcocks, are another frequent source of wintertime woes. Disconnecting hoses and storing them indoors prior to the first hard freeze goes a long way.
Though freezeless faucets do provide protection from freezing pipes, they aren’t totally fail-safe in extreme cold. Taking the proper precautions in these key areas can go a long way in preventing frozen pipes.
Prepare Your Home Before Winter
For Minnesota homeowners, the best way to prevent frozen pipes in the event of a power outage is to prepare your home well in advance. Besides being inconvenient, frozen pipes can make your home susceptible to costly water damage. With a little preparation, you can ensure that your plumbing is safe from the cold winter weather.
Taking these steps now, before the frigid temperatures arrive, can be the key to keeping your home safe and warm.
Insulate Exposed Pipes
Insulating pipes that are exposed and easily accessible is a great first step. Apply foam pipe insulation to protect pipes in unheated areas like basements, attics, and crawlspaces.
Want more protection from the cold? Heat tape is a proven safeguard against freezing conditions. Even insulated pipes should be periodically checked for wear, gaps in insulation, etc.
This straightforward bit of upkeep can help prevent expensive pipe breaks even in the case of extended outages.
Seal Gaps and Cracks
Use caulk to seal the gaps around your windows, doors, and any plumbing entry points. This is an important step to keep cold air from seeping into your home.
Caulk or spray foam insulation is a good solution for cracks in walls or floors. Be mindful to check places where pipes come into the house, and make sure exterior doors and windows seal tightly.
This simple step not only protects your pipes from freezing, but will help keep your home nice and cozy.
Maintain a Warm Indoor Temperature
Maintaining your home at a healthy temperature year-round is essential. If you are going to be away, set the thermostat to at least 55°F.
When it’s dangerously cold, minimize large night-time temperature swings. Space heaters are an effective way to provide extra warmth in colder areas, but use them safely.
If traveling, enlist a trusted neighbor or friend to watch over your home, keeping an eye on indoor temperatures and plumbing.
Prevent Frozen Pipes During Power Outages
When the temperature dips below freezing and the power goes out, protecting your plumbing system can prevent expensive repairs. By following some simple, commonsense tips, you can protect your home—and your water supply—by preventing frozen pipes and ensuring your water lines continue to flow.
1. Let Faucets Drip
Since moving water is much harder to freeze, keep faucets dripping, especially those on outside walls. A stream no thicker than a pencil is enough to ensure water keeps flowing without wasting too much.
When temperatures drop sharply, warmer water — above 40°F — will start coming into your house. This warmer water will help to push out the colder water in the pipes, reducing the chance that it will freeze.
Pay special attention to sink usage in kitchens and bathrooms, and track usage over time to find the right balance between safety and conservation.
2. Open Cabinet Doors
Leave cabinet doors open to allow warmer indoor air to circulate around your pipes. This is particularly crucial for the spaces beneath sinks and along exterior walls.
Specifically, overnight exposure to circulating air can reduce freezing risk by up to 87%. Make sure nothing obstructs airflow and take out anything kept in these areas.
3. Use Portable Heaters Safely
Position heaters near vulnerable pipes, but don’t create dangerous situations, such as with extension cords. Never leave space heaters unattended and turn them off when not needed.
Safety is paramount. Correct placement and monitoring greatly reduce the risks.
4. Use Blankets to Wrap Pipes
Use blankets or towels to provide extra insulation. Wrap them in insulation, and seal them with duct tape, particularly in outside walls.
Timing is essential, so you’ll want to remove insulation as the outside air warms up to prevent trapping moisture.
5. Drain Water from Pipes if Necessary
If you can’t keep indoor temperatures above 40°F, turn off your main water supply and drain pipes entirely. This is important for preventing damage when pipes are subject to extended freezing.
Outdoor hoses and sprinkler systems need to be drained as well before winter.
What to Do If Pipes Freeze
Frozen pipes, especially during a cold snap, can lead to significant water damage if not addressed promptly. Taking immediate action to prevent a pipe burst is crucial for maintaining your residential plumbing. Here are some essential steps to find and safely thaw frozen pipes, ensuring your plumbing system remains intact and your home stays protected.
Identify Frozen Sections of the Pipe
Begin by checking any exposed pipes for frost build-up or bulging, two of the most common signs that pipes have frozen. You can additionally touch test the pipes to locate extremely cold areas. A simple infrared thermometer works great for checking the temp of exposed pipes, easily confirming frozen sections.
When water stops flowing or comes out only as a trickle, that means a pipe has frozen. The American Red Cross emphasizes this warning sign. Pay special attention to areas located close to outside walls or areas that are not heated, as these are the areas most susceptible.
Safely Thaw Frozen Pipes
Thawing needs to be done very carefully to prevent additional damage. Begin with a hairdryer, electric heating pad or space heater to slowly warm the affected area. Start at the tap end and slowly move towards the source.
Don’t use boiling water or an open flame to thaw pipes, as these methods may severely damage pipes. Keep a close watch as thawing occurs, to make sure the thaw is being done safely and gradually to avoid building pressure.
Check for Leaks After Thawing
After the water has begun flowing again, look for leaks that may have formed in the pipes. Check around your home for signs of leaks, such as water stains or corrosion on fittings. Keep faucets turned on until they run completely clear.
Fix leaks quickly when pipes burst, they can flood your home with thousands of gallons of water, causing significant damage.
Contact a Professional for Severe Cases
If a pipe bursts or you are unable to identify the frozen area, call a licensed plumber right away. Professionals are equipped with specialized tools and knowledge to deal with more serious problems, making sure that repairs are done safely and properly.
The sooner you take action, the less risk there will be of additional water damage.
Safety Precautions During Power Outages
During an extended Minnesota power outage, safety would be our first concern, particularly if the outdoor temperature poses the danger of frozen pipes. Taking extra precautions to insulate pipes can help prevent injuries and keep everyone who lives in your home safe.
Avoid using unsafe heating methods
However you choose to heat your home, do it safely. Stoves, ovens, and grills should not be used indoors, as these items are not intended for space heating and can produce dangerous gases.
Use only heaters approved for indoor use, such as electric space heaters equipped with automatic shut-off. Keep flammable objects such as blankets and curtains at least three feet away from anything that gets hot.
This easy precaution can protect you from unintended household fires. Educating all members of your household about these practices will help keep everyone safe during an outage.
Monitor for signs of pipe damage
Pipes that freeze and burst can result in thousands of dollars worth of damage. Listen for alarming noises such as banging or hissing, which can be signs of freezing or pressure build-up.
Check for discoloration or wet spots on walls and ceilings, signs of possible leaks. A drop in water pressure, or water running slowly from taps, can be other indicators that pipes are frozen.
If something is damaged, take pictures to make an insurance claim, if required.
Ensure proper ventilation with heaters
If you use a heater, open a window just enough to keep fresh air flowing and prevent carbon monoxide from building up. Place carbon monoxide detectors to help you detect toxic air and evaluate air quality.
Keep heater vents clear and replace filters regularly to maximize heating efficiency.
