Running water to prevent pipes from freezing is a simple yet effective method. During cold weather, it’s recommended to let water drip from faucets served by exposed pipes. This practice helps prevent freezing by keeping water moving within the pipes.
How Often Should You Run Water to Prevent Freezing?
Why Do Pipes Freeze?
Pipes freeze when temperatures drop below freezing, typically around 32°F (0°C). When water freezes, it expands, which can cause pipes to burst. This is especially common in unheated or poorly insulated areas, like basements, attics, and exterior walls.
How to Prevent Pipes from Freezing
To prevent your pipes from freezing, consider the following strategies:
- Let Faucets Drip: Allow a slow drip of water from faucets connected to exposed pipes. This helps maintain water movement, reducing the risk of freezing.
- Keep the Heat On: Maintain a consistent temperature in your home, even when you’re away. Set your thermostat to at least 55°F (13°C).
- Insulate Pipes: Use pipe insulation or heat tape on exposed pipes, especially in unheated areas.
- Seal Cracks and Openings: Close gaps in walls, floors, and ceilings to prevent cold air from reaching pipes.
How Often Should You Let Water Drip?
During extreme cold, it’s advisable to let faucets drip continuously, especially at night or when temperatures are at their lowest. A steady drip is usually sufficient, but in severe conditions, a small stream may be more effective.
Benefits of Running Water
Running water helps prevent freezing by:
- Maintaining Water Flow: Constant movement reduces the chance of ice forming.
- Relieving Pressure: If freezing does occur, running water can help relieve pressure, reducing the risk of a burst pipe.
Practical Example
Consider a scenario where temperatures are forecasted to drop below 20°F (-6°C). In this case, you should:
- Identify faucets connected to exposed pipes.
- Allow these faucets to drip slowly overnight.
- Monitor the temperature and adjust the flow if necessary.
People Also Ask
What Temperature Do Pipes Freeze?
Pipes typically begin to freeze when temperatures reach 20°F (-6°C) or lower. However, poorly insulated pipes in unheated areas may freeze at temperatures closer to 32°F (0°C).
How Can I Tell If My Pipes Are Frozen?
Signs of frozen pipes include little or no water flow from faucets, visible frost on pipes, or unusual sounds when turning on the faucet. If you suspect a frozen pipe, act quickly to thaw it safely.
What Should I Do If My Pipes Freeze?
If your pipes freeze, turn off the water supply and open the faucet to relieve pressure. Use a hairdryer or space heater to gently warm the pipe, starting from the faucet and moving toward the frozen section.
Can Running Water Alone Prevent Freezing?
Running water is a helpful measure, but it should be combined with other preventive actions like insulation and maintaining indoor temperatures to be most effective.
Is It Expensive to Run Water to Prevent Freezing?
The cost of running water is generally low compared to the potential expense of repairing burst pipes. A slow drip uses minimal water and can prevent costly damage.
Summary
In cold weather, letting water drip from faucets connected to exposed pipes is a practical way to prevent freezing. This method, combined with proper insulation and maintaining indoor temperatures, can effectively protect your plumbing.
