How to Prevent Pipes From Freezing Without Power

Power outages can occur during major winter storms in Texas, where temperatures dip below freezing. When you lose power to your home, indoor temperatures will gradually drop. If the power remains off for an extended period, your house could get cold enough that your pipes freeze.

When your pipes freeze, it can lead to much bigger problems than just losing access to running water. As water inside the pipes freezes, it expands, which puts pressure on the pipes. This pressure can cause the pipes to crack or burst, leading to significant water damage and costly repairs.

So, what do you do for frozen pipes? First, it’s essential to know how to prevent pipes from freezing without power, and second, to understand how to take action if they do freeze.

How to Prevent Freezing Pipes

You can do several things to help prevent pipes from freezing even when you do not have power and heat.

#1. Leave Water Trickling From the Faucets

Turning on your faucets and allowing water to flow will prevent the pipes from freezing and bursting even in cold weather. It’s advisable to leave both cold and hot water faucets trickling if possible, as this keeps water moving in all pipes. You want to turn on several faucets in different areas of the home, including each of your bathrooms and the kitchen. The water does not need to be turned on all the way—just a small trickle will suffice to maintain flow.

#2. Open Sink Cabinet Doors

The air underneath sink cabinets can get colder than the air in the rest of the house. By opening the sink cabinet doors, you allow warmer air to circulate under the sink, helping to prevent the water pipes from freezing. This is most effective when combined with a heat source, but it’s still a good practice during a power outage.

#3. Shut Off the Water Main and Turn on Faucets

Another option to prevent freezing pipes when you lose power is to drain the water lines. Start by shutting off the valve for the water main. Next, turn on the faucets to drain the water from the water lines. While some water will remain in the pipes, there will only be a small amount, reducing the risk of freezing and bursting the plumbing lines.

If you have a tank-type water heater, you should also drain the water from the heater to prevent it from freezing. Once the water main has been turned off, use the drain valve on the water heater to drain the water out of it. Alternatively, you can turn on the hot water at different faucets to drain it.

It’s important to note that draining your pipes will completely cut off water to the home, so this method should be used as a last resort.

#4. Wrap Exposed Pipes With Heavy Towels

If you have exposed pipes in your basement, garage, or crawl space, you can protect them from freezing by wrapping them in heavy towels to help insulate the pipes. However, for better protection, consider using purpose-made pipe insulation or wrapping pipes with foam rubber or fiberglass sleeves. It’s still a good idea to turn on your faucets to a trickle to maintain water flow.

#5. Keep Your Garage Door Closed

If your water heater or washing machine is located in the garage, or you have water lines running through exterior walls, you want to prevent freezing temperatures inside your garage. The easiest way to do this is by keeping the garage door closed until your power is restored and you have heat. Additionally, seal any windows or doors that let in drafts to prevent cold air from entering.

Other Useful Tips

If you have a wood-burning or pellet stove in your kitchen, you can keep a fire burning to keep this part of the home warmer. However, you should still use other methods to prevent water pipes from freezing in other parts of the house.

Some people might consider using a portable kerosene heater to help keep pipes from freezing. However, you should never use kerosene heaters indoors because they should not be used in enclosed areas. As the kerosene burns, it releases carbon dioxide, carbon monoxide, sulfur dioxide, and nitrogen dioxide—all harmful chemicals you should avoid breathing.

Frequently Asked Questions About Frozen Pipes

Q: How do I know if my pipes are frozen?

A: If you suspect your pipes are frozen, there are a few signs to watch for. The most common sign is when you turn on a faucet, and little to no water comes out. This could indicate that the water in the pipe has frozen. Other signs pipes are frozen include visible frost on exposed pipes, unusual noises like clanking or banging when water is turned on, and strange odors coming from the faucet, which can happen if ice is blocking the pipe. Knowing how to tell if pipes are frozen is crucial, so be sure to inspect areas prone to freezing, such as exterior walls, basements, and under sinks, to confirm if your pipes are frozen.

Q: What do I do if my pipes are frozen?

A: If you discover your pipes are frozen, you need to pinpoint the location in the water system where they froze. Usually, it will be on an exterior wall or where the water main enters the home. However, if the water only appears frozen in the kitchen or bathroom, the pipes under the cabinet are probably frozen.

First, determine if the pipes are partially frozen or frozen solid. Turn on the faucet—if water trickles out, the pipes are partially frozen. You can then turn on other faucets to help move the water and melt the ice. If the pipes are frozen solid, you’ll need to apply heat. Once the power is restored, wrap the pipe with a heating pad or electric blanket to warm it up and thaw the ice. Alternatively, you can use an electric space heater to warm the air around the pipes, which will gradually melt the ice inside.

Q: What do I do if my pipes freeze and burst?

A: If your pipes freeze and burst, you need to act quickly to contain the water and minimize damage. Start by shutting off the water main to your home to stop the flow of water. Then, open the faucets to drain any remaining water from the plumbing lines.

Next, locate the burst pipe. Begin by checking under sink cabinets and exposed pipes for leaks. If the burst pipe is in an inaccessible area, look for signs of water damage, such as dripping water from the ceiling or wet spots on drywall.

Once you find the burst, take steps to contain the water damage until a plumber can repair the pipe. Additionally, notify your homeowner insurance provider and file a claim, as the water damage may be covered.

Q: What temperature should I leave my house at to prevent my pipes from freezing?

A: To prevent pipes from freezing, it’s generally recommended to keep your home’s temperature at least 55°F (13°C), even when you’re not home. This helps maintain enough warmth throughout the house to prevent the water in the pipes from freezing, especially during a power outage or severe cold snap.

Q: How long does it take for pipes to freeze?

A: The time it takes for a pipe to freeze can vary depending on factors such as insulation, pipe material, and the external temperature. However, when can pipes freeze? Pipes can start freezing within a few hours when temperatures drop below 32°F (0°C). It’s especially important to take precautions when the temperature is expected to stay below freezing for an extended period.

Q: Can pipes freeze in one night?

A: Yes, pipes can freeze in one night, especially if the temperature drops rapidly and stays below freezing. This is why it’s crucial to know when to worry about pipes freezing, such as during sudden cold fronts or extended periods of freezing temperatures without power.

Q: At what temperature does water freeze, and why does it matter for pipes?

A: Water freezes at 32°F (0°C). When the temperature drops to this point or below, any water inside pipes can freeze, expand, and potentially cause the pipes to burst. This is why it’s essential to monitor the temperature inside your home and take preventive measures during cold weather.

Q: How do I prevent pipes from freezing without power?

A: Preventing pipes from freezing without power requires a few proactive steps: keep water trickling from faucets, open sink cabinet doors to allow warmer air to circulate around pipes, and insulate exposed pipes with towels or pipe insulation. If the power outage is prolonged, consider shutting off the water main and draining the pipes to minimize the risk of freezing.

How to Prevent Pipes From Freezing in the Future

One of the most effective ways to prevent pipes from freezing again is to have your water supply lines insulated. Proper insulation helps protect your pipes from colder temperatures and significantly reduces the risk of them freezing.
