Quick Answer
If stored water freezes in winter months, it can expand and burst pipes, causing leaks and damage to the water storage system. This can result in costly repairs and potentially leave occupants without access to clean water. Frozen water can also contaminate the water supply.
Water Expansion and Pipe Damage
Water expands by approximately 9% when it freezes. This can cause significant stress on pipes, especially if they are not designed to handle the pressure. When water freezes, it forms ice crystals that push against the walls of the pipe, causing it to burst. This is often the case with pipes that are not insulated or are exposed to cold temperatures for extended periods.
Prevention Techniques
To prevent water from freezing in winter months, consider implementing the following techniques:
- Insulate exposed pipes in unheated areas, such as the garage or basement. Use foam pipe insulation or heat tape to keep pipes warm.
- Disconnect and drain hoses from outdoor faucets to prevent water from freezing in the hoses.
- Consider installing a whole-house water filter with a built-in heating element to keep the water warm.
- Allow cold water to drip from the faucet served by exposed pipes. Running water is less likely to freeze than standing water.
- Open cabinet doors to allow warm air to circulate around pipes.
Repair and Maintenance
If pipes do burst due to frozen water, act quickly to minimize damage. Turn off the main water shut-off valve and call a plumber to repair the pipe. In the meantime, use a bucket to catch any water that is leaking from the pipe. To prevent future occurrences, consider installing freeze-proof faucets or frost-proof spigots, which are designed to withstand freezing temperatures. Regularly inspect pipes for signs of damage or wear and tear, and address any issues promptly.
