Inadequate maintenance is often a key factor in fire sprinkler system failures. To keep these systems dependable, it’s essential to follow the inspection, testing, and maintenance (ITM) protocols outlined in NFPA 25, the standard for water-based fire protection systems. Systems subjected to cold conditions face heightened risks. In this guide, we’ll walk through effective winterization steps. If you need immediate assistance, contact 1st Option Fire Protection at (346) 528-5971.
As temperatures drop, certain areas that go unnoticed during warmer months may become vulnerable. These include entryways, stairwells, large vacant rooms, skylights, and poorly insulated spaces.
In locations where maintaining at least 40°F isn’t possible, dry pipe or antifreeze sprinkler systems are commonly used. These setups may require more in-depth evaluations and ongoing upkeep to prevent freezing. For expert help with installation, maintenance, or service in the Houston area, give us a call at (346) 528-5971.
Before winter sets in, test antifreeze systems to ensure the antifreeze solution can handle the expected low temperatures. If it’s not sufficiently protective, it must be drained and replaced with an antifreeze solution that meets NFPA 25, section 5.3.4 requirements.
Keep the wet portions of the dry pipe valve at or above 40°F. Inspect the enclosure daily to confirm the proper temperature is maintained, or weekly if a low-temperature alarm is installed. Low point and auxiliary drains should be emptied after each system operation, before freezing weather hits, and as needed thereafter.
The frequency of draining during cold weather depends on the system’s condensation levels. This could mean daily, weekly, or monthly checks. Our team of professional fire contractors serving the Houston Metroplex can handle these services—just call us at (346) 528-5971.
Steps to Winterize a Fire Sprinkler System:
1. Close the upper valve.
2. Open the lower valve to drain accumulated water.
3. Close the lower valve, reopen the upper valve, and allow more water to gather.
4. Repeat until no more water is released.
5. Once finished, replace the plug or nipple and cap on the lower valve.
Cold weather can create significant challenges for the fire protection industry. Without proper maintenance, fire protection systems may freeze, burst, or fail to operate during an emergency. Ensuring these systems are properly cared for is critical to their reliable performance.
