Frozen pipes occur when water inside plumbing freezes during prolonged exposure to low temperatures, expanding inside the pipe and increasing pressure, which can cause cracks or pipe bursts.
As a local plumbing company we know extremely familiar with winter blankets Nashville, TN, with its chilly embrace, homeowners face a common and potentially costly issue: frozen pipes. Understanding why pipes freeze and learning preventive measures can save you from the headache and expense of dealing with burst pipes. In this blog post, we’ll delve into the reasons behind this winter woe and provide practical tips to safeguard your plumbing.
1. The Nashville Freeze: Understanding the Culprits
Cold Snaps and Temperature Drops: Nashville winters can bring sudden drops in temperature, causing pipes to freeze. When temperatures fall quickly, standing water inside pipes turns into ice, expanding and increasing pressure within the pipe walls.
Poor Insulation: Homes lacking proper insulation are more vulnerable to freezing pipes. Without adequate protection, cold air can easily reach exposed plumbing, especially in attics, crawl spaces, and exterior walls.
2. Location of Pipes in Unheated Areas
Pipes located in unheated spaces such as garages, basements, attics, or exterior walls are more likely to freeze. These areas are often not insulated or heated properly, allowing cold air to directly affect the plumbing.
3. Sudden Weather Changes
Rapid temperature drops, especially overnight, can catch homeowners off guard. When the temperature dips below freezing unexpectedly, water inside pipes can freeze before homeowners have time to take preventive action.
4. Poor Air Circulation Around Pipes
Pipes that are surrounded by stagnant, cold air are more likely to freeze. Proper airflow helps maintain a more stable temperature, while trapped cold air increases the risk of freezing and pressure buildup.
5. Neglected or Unused Plumbing
Pipes that are not frequently used, such as those in guest bathrooms, outdoor spigots, or vacation homes, are more prone to freezing. Without regular water flow, the water inside becomes still and freezes more easily.
6. Preventive Measures: Shielding Your Pipes from Winter’s Grasp
Insulate, Insulate, Insulate: One of the most effective preventive measures is insulating your pipes. Focus on areas prone to cold exposure, such as attics, crawl spaces, and exterior walls. Pipe insulation sleeves or wrapping can act as a protective barrier, reducing the risk of freezing.
Seal Cracks and Gaps: Inspect your home for any cracks or gaps that could allow cold air to enter. Sealing these openings helps maintain warmer indoor temperatures and reduces the chances of pipes freezing.
7. Taking Action: What to Do When Winter Strikes
Dripping Faucets for the Win: When temperatures plummet, allow faucets to drip slowly. This keeps water moving through the pipes, reducing the risk of freezing and pressure buildup.
Keep the Heat On: Maintain a consistent indoor temperature, even when you’re away. Turning down the heat too much can increase the risk of frozen pipes. Aim for at least 55°F (13°C) to protect your plumbing system.
8. What to Do if Pipes Start to Freeze
If you suspect your pipes are freezing, act quickly. Open faucets to relieve pressure and gently warm the pipe using a hairdryer or warm towels. Never use open flames. If you’re unsure or the pipe has already burst, contact a professional plumber immediately to prevent further damage.

Frequently Asked Questions
Why do pipes freeze during winter?
Pipes freeze when temperatures drop low enough to turn the water inside them into ice. As water freezes, it expands, increasing pressure inside the pipe and potentially causing it to crack or burst.
At what temperature do pipes freeze?
Pipes can begin to freeze when temperatures drop to around 20°F (-6°C) or lower, especially if the cold conditions last for several hours or more.
Should I let my faucets drip in freezing weather?
Yes. Letting faucets drip slowly keeps water moving, which helps prevent freezing. This is especially helpful for pipes along exterior walls or in unheated areas.
What should I do if my pipes freeze?
Turn off the water supply immediately and try to gently thaw the pipe using a hair dryer or warm towels. Never use open flames. If you’re unsure or the pipe is inaccessible, call a licensed plumber.
