How to Keep Pipes From Freezing: 7 Expert Tips to Prevent Burst Pipes This Winter

How to Keep Your Pipes from Freezing

Frozen pipes are one of the leading causes of costly winter water damage. When water inside a pipe freezes, it expands, creating pressure that can crack or burst the pipe. Fortunately, a few simple preventative steps—such as insulating exposed pipes, sealing air leaks, disconnecting outdoor hoses, and maintaining a consistent indoor temperature—can dramatically reduce the risk of frozen plumbing and expensive repairs

Whether you’re preparing your home for winter or expecting a severe cold snap, this guide explains how to protect your plumbing, what to do if your pipes freeze, and how to prevent burst pipes before they happen.

Quick Answer: How Do You Keep Pipes From Freezing?

• Disconnect garden hoses
• Shut off outdoor faucets
• Seal cold air leaks
• Keep your thermostat consistent
• Open cabinet doors
• Let faucets drip during extreme cold
• Know where your main shutoff valve is
• Install heat tape where appropriate
• Check crawl spaces and attics

These simple steps can help protect your plumbing system throughout the winter months.

Why Do Pipes Freeze?

Pipes freeze when temperatures remain below freezing long enough for the water inside them to turn into ice. As water freezes, it expands by approximately 9 percent, increasing pressure inside the pipe.

Contrary to popular belief, pipes don’t always burst while they’re frozen. They often crack or split as the ice begins to thaw and water pressure returns.

1. Insulate Exposed Pipes

One of the most effective ways to prevent freezing is by insulating your pipes. Proper insulation helps retain heat and prevents the water inside the pipes from turning into ice. You can use foam pipe insulation, which is easy to install and provides good thermal protection. Make sure to cover all exposed pipes, focusing on areas that are particularly susceptible to cold, such as basements, crawl spaces, and exterior walls.

2. Keep a Steady Flow of Water

Another way to prevent freezing is by keeping a steady flow of water through your drains. Allowing a small trickle of water to run through your faucets can significantly reduce the risk of freezing. While this may not be practical for long periods, it can be a helpful measure during especially cold spells. The continuous movement of water through the pipes helps maintain a temperature above freezing.

3. Seal Gaps and Cracks

Cold air can seep through gaps and cracks around your pipes, contributing to the risk of freezing. Inspect your home for any spaces where cold air might enter, particularly around windows, doors, and the foundation. Seal these gaps with caulk or weatherstripping to keep the cold out and the warmth in.

4. Install Heat Tape or Cables

Heat tape or heating cables can provide an additional layer of protection for your pipes. These electric devices are designed to keep pipes warm by providing consistent heat. They’re particularly useful for pipes located in unheated areas. Make sure to follow the manufacturer’s instructions for installation to ensure safety and effectiveness.

5. Open Cabinet Doors

If you have pipes located inside cabinets, such as those under your kitchen sink, consider leaving the cabinet doors open. This allows warm air from the rest of your home to circulate the pipes, helping to maintain a higher temperature and prevent freezing.

6. Maintain a Consistent Temperature

Keeping your home at a steady temperature, even when you’re away, can prevent sudden drops that might cause your drains to freeze. Aim to keep your thermostat set to the same temperature during the day and night. If you’re planning to be away for an extended period, set your thermostat to at least 55°F to prevent freezing.

7. Disconnect and Drain Garden Hoses

Don’t forget about your outdoor plumbing! Disconnect and drain garden hoses before the onset of freezing temperatures. This simple step prevents water from being trapped in the hose, causing backflow into your pipes.

Conclusion

Taking these precautionary measures can help ensure your pipes remain functional throughout the winter. You can effectively protect your drains from freezing by insulating your pipes, maintaining a steady flow of water, sealing gaps, and using heat tape. Keep your home warm and your plumbing in top shape to enjoy a hassle-free winter season.

Frequently Asked Questions

Can frozen pipes thaw on their own?

Yes, but it’s safer to thaw them gradually while monitoring for leaks. A pipe that appears fine while frozen may begin leaking as it warms.

Should I leave my faucets dripping all winter?

No. Let faucets drip only during periods of extreme cold when pipes are at increased risk of freezing.

Will pipe insulation completely prevent freezing?

Insulation greatly reduces the risk but cannot guarantee protection during prolonged or severe cold. Combining insulation with indoor heat and proper winter preparation provides the best protection.

Which pipes freeze first?

Pipes located in unheated spaces, exterior walls, crawl spaces, garages, and outdoor plumbing freeze first.

What temperature should I keep my home when I’m away?

Experts generally recommend maintaining an indoor temperature of at least 55°F while you’re away during winter.

Final Thoughts

Frozen pipes can lead to expensive repairs, water damage, and major disruptions during the coldest months of the year. Fortunately, a little preparation goes a long way.

By insulating exposed pipes, protecting outdoor plumbing, sealing drafts, maintaining consistent indoor temperatures, and knowing how to respond if pipes freeze, you can greatly reduce the risk of burst pipes this winter.

Taking these preventative steps now will help keep your plumbing system working properly, protect your home from water damage, and give you peace of mind throughout the winter season.
