5 tips to prevent frozen pipes

As temperatures drop, the risk of frozen pipes rises. When water freezes inside pipes, it expands, increasing the chance of a pipe bursting and causing costly damage. Fortunately, there are simple steps you can take to prevent frozen pipes, recognize the signs of freezing, and thaw pipes safely if needed.

How to prevent frozen pipes

Preventing frozen pipes starts with proper insulation, heating, and maintenance. Follow these best practices to keep your pipes from freezing:

1. Insulate vulnerable pipes

Pipes in basements, attics, exterior walls, and garages are the most susceptible to freezing. Insulating these pipes with foam pipe insulation or heat tape provides a protective barrier against extreme temperatures.

2. Seal leaks and drafts

Cold air can seep in through cracks and openings around windows, doors, and foundation walls. Sealing these gaps helps maintain indoor temperatures and prevents pipes from being exposed to freezing air.

3. Keep water moving

Letting faucets drip during extreme cold reduces pressure in the pipes, decreasing the likelihood of freezing. This is especially important for pipes located along exterior walls.

4. Maintain adequate heat

Keep your thermostat set to at least 50 degrees Fahrenheit, even when you’re away. In unheated areas like basements or garages, consider using space heaters to maintain a safe temperature.

5. Monitor pipe conditions

Smart monitoring systems, like Sensor Solutions by HSB, can track building temperatures and alert you to potential freezing risks, allowing you to act before pipes freeze.

How to tell if pipes are frozen

If you suspect a frozen pipe, look for these warning signs:

• No water or reduced flow when turning on a faucet
• Frost or condensation forming on exposed pipes
• Unusual odors coming from drains, which can indicate a blockage due to frozen water

If you notice any of these signs, act quickly to prevent the pipe from bursting.

What to do if your pipes are frozen

If you discover frozen pipes, follow these steps to safely thaw them:

1. Turn on the faucet

Opening the faucet relieves pressure and allows melted water to flow out, helping the thawing process.

2. Apply heat

Use a hair dryer, space heater, heating pad, or warm towels to gradually thaw the pipe. Never use an open flame, as this can cause a fire hazard.

3. Continue heating until water flows freely

Once water is running at full pressure, continue applying heat for a few minutes to ensure all ice is melted.

4. Check for leaks

Frozen water expands, which can cause pipes to crack. Inspect all faucets and pipes for leaks. If a pipe has burst, shut off the main water supply immediately and call a plumber.

Long-term solutions to prevent frozen pipes

• Drain and purge outdoor plumbing before winter, including hose bibs and sprinkler systems
• Maintain fire suppression systems by ensuring pipes are properly drained in unheated areas
• Install an automatic shut-off system that detects excessive water flow in case of a burst pipe
• Keep detailed maintenance records to track weak spots in your plumbing system and improve future prevention efforts

By taking proactive steps, you can prevent frozen pipes and avoid costly water damage. Stay vigilant during cold weather and act quickly if you suspect freezing to keep your home or business safe all winter long.
