Five Ways To Prevent Fire Sprinkler System Freezing
As temperatures drop, protecting your fire sprinkler system from freezing is necessary to ensure it functions when needed. Frozen sprinkler pipes not only risk damage to your system but can also lead to costly repairs and potential safety issues. Here are five straightforward steps to prevent fire sprinkler system freezing and keep your system in top shape all winter.
1. Regularly Check and Drain Auxiliary Drains: Dry-pipe sprinkler systems are used in areas where maintaining temperatures above 40°F isn’t feasible, like unheated warehouses. Though they don’t hold water continuously, condensation or testing can leave residual water that may freeze and block pipes. Check and drain auxiliary drains (drum drips) regularly, especially in colder months, to remove collected water.
2. Insulate Exposed Pipes: Insulate exposed sprinkler pipes to protect them from freezing, especially in colder climates. Use materials like batt, loose-fill, or rigid polyurethane foam, choosing the best option for your climate and pipe locations. Focus on vulnerable areas such as attics, crawl spaces, and soffits to block cold air and keep your pipes warm.
3. Maintain Adequate Indoor Heating: If possible, keep temperatures in your facility above 40°F, especially in areas where your sprinkler pipes are located. For spaces that tend to be colder, consider using space heaters (in compliance with safety guidelines) to prevent freezing. It’s essential to maintain heat in all areas with fire sprinkler pipes, as even a small drop in temperature can freeze water in pipes, especially in extreme weather conditions.
4. Consider Heat Tracing for Extra Protection:Use heat tracing, or heat tape, to safeguard sprinkler pipes, especially wet-pipe systems that hold water. This technology delivers consistent heat to prevent freezing. Install self-regulating or constant-wattage heating cables on exposed pipes with help from a certified technician. Follow NFPA standards to ensure safety and compliance.
5. Schedule Routine Inspections and Maintenance: Simple checks help, but regular inspections by certified fire protection professionals keep your sprinkler system winter-ready. They can spot damage, corrosion, or draining issues that cause freezing. Increase inspections during cold weather to monitor pressure and resolve problems quickly. For extra protection, use antifreeze solutions for wet-pipe systems, ensuring they follow approved guidelines.
