Why You Should Open Cabinets in Cold Weather: Protecting Pipes from Freezing

Opening cabinets in cold weather, especially under sinks, is a common practice to prevent pipes from freezing. This simple action can significantly reduce the risk of costly repairs and prevent the hassle of dealing with burst pipes. Here's why this method is so effective and recommended:

Heat Circulation

One primary reason to open cabinets during cold weather is to promote heat circulation. Cabinets often have a significant amount of insulation, and keeping them closed traps cold air next to the pipes. By opening the doors, warmer air from the room can easily circulate around the pipes. This helps maintain a consistent temperature around the pipes, keeping them above freezing temperatures.

Preventing Ice Formation

When pipes freeze, water inside them turns to ice, causing the pipe to expand and eventually burst. Exposing pipes to warmer air through open cabinet doors reduces the risk of internal ice formation. The increased airflow helps keep the ambient temperature around the pipes stable and prevents the temperature from dropping to the freezing point.

Warm Water Flow

Another effective strategy is to let a faucet drip slightly. This ensures that water flows continuously through the pipes, making it harder for them to freeze. By keeping the cabinet doors open, the warm air has a clear path to reach the pipes, enhancing the effectiveness of the dripping method.

Proactive Measures for Cold Weather Protection

Opening cabinets in cold weather is a proactive measure to safeguard your plumbing system. It’s particularly important if your sink is installed on an outside wall, as the exterior exposure to cold temperatures increases the risk of freezing. If you have a kitchen sink under an outside wall, leaving just the cabinet doors under the sink open can be sufficient to keep the pipes warm. This targeted approach ensures that the only area exposed to potential freezing is the vulnerable part of the plumbing.

Conclusion

While it might seem like a simple and sometimes overlooked task, opening cabinets in cold weather can make a significant difference in protecting your plumbing. By promoting heat circulation, preventing ice formation, and maintaining warm water flow, you can keep your pipes safe from the damaging effects of freezing. This preventive measure can save you from expensive repairs and the inconvenience of thawing frozen pipes.
