What to Do When Your Fire Sprinkler is Leaking

Fire sprinklers are your first line of defense against fire, but a leaking sprinkler system can compromise your protection and cause significant damage. Acting quickly and effectively can prevent further issues. 

Whether you're a homeowner, business owner, or property manager, understanding how to address a leaking fire sprinkler is essential for maintaining both safety and property integrity. This guide will explain why fire sprinklers leak, what to do immediately, and how to prevent future issues.

Why Is Your Fire Sprinkler Leaking?

Understanding why your fire sprinkler leaks is crucial for determining the right solution and minimizing damage. Here are some common causes:

• Corrosion: Over time, moisture and oxygen cause pipes and sprinkler heads to corrode, weakening the system and causing leaks. Microbiologically Influenced Corrosion (MIC) can accelerate this process, leading to contaminants that affect the system's integrity.
• Damage: Physical damage from construction, forklifts, or other equipment can compromise fire sprinkler pipes or heads, leading to leaks and potentially affected areas.
• Equipment Failure: Manufacturing defects, poor installation, or wear and tear can cause sprinkler heads or seals to malfunction, which may lead to system failure.
• Freezing: Freezing temperatures can crack pipes and cause leaks, especially in wet-pipe systems.
• Aging Systems: Older sprinkler systems with inadequate maintenance can develop leaks due to wear and tear, potentially resulting in a system failure.

By understanding the potential causes, you can take the proper steps to fix the issue and restore your sprinkler system's functionality.

How to Identify a Leaking Fire Sprinkler 

Recognizing leaking sprinklers early can save you from major water damage. Here are common signs to look out for:

• Visible Drips: Water dripping from the fire sprinkler head or pipes is the most obvious sign.
• Water Stains or Damp Spots: Discoloration on walls or ceilings, especially near sprinkler heads, often points to a hidden leak.
• Rust or Corrosion: Corroded pipes or sprinkler heads can indicate a deteriorating system, which may soon cause leaks.
• Pressure Fluctuations: A sudden drop in water pressure or unusual noises from the sprinkler system can signal an underlying issue.

If you happen to notice any of these signs, addressing the issue immediately is essential to prevent further damage.

What to Do Immediately When You Find a Fire Sprinkler Leaking

If you notice a fire sprinkler leaking, it's important to follow the right steps to avoid further damage and protect your building. Here's what to do immediately:

1. Ensure Safety First

   • Check for Fire: Quickly confirm whether the leak is due to a fire. If it’s an active fire, evacuate and call the fire department immediately.
   • Evacuate if Necessary: If the leak is near electrical systems or poses a flooding risk, evacuate the building to prevent further danger.

2. Shut Off the Water Supply

   • Minimize Damage: Turn off the water supply to stop further flooding. Even small leaks can lead to significant damage, especially in sensitive areas like electrical rooms.
   • Act Quickly: The faster you turn off the water, the less damage you’ll face.

3. Assess the Leak

   • Inspect the Situation: If it’s safe, check for pooling water or damp spots around the leak. This information will help the technician when they arrive.
   • Document the Damage: Take photos or notes to share with the repair professional. The more details you provide, the faster the repair process will be.

4. Contact a Professional Fire Protection Service

   • Call All About Sprinklers: Contact a certified fire protection company like All About Sprinklers. Provide as many details as possible about the leak’s location and severity.
   • Get Expert Help: Do not attempt to fix the leak yourself—fire sprinkler systems require professional handling to ensure they function properly and safely.

Repairs You Can Expect for a Leaking Fire Sprinkler System

Once a technician arrives to inspect the leak, they'll provide a solution based on the cause. Here’s what you can expect:

• Corroded Pipes:
  • Repair or Replacement: If corrosion is the cause, the technician will replace the affected sections of the pipe. Corrosion often occurs internally, so they’ll use specialized tools to fully inspect the system.
  • Minimize Future Risks: After repairs, a thorough check of the system will be done to ensure other areas aren’t at risk of corrosion.
• Damaged Sprinkler Heads:
  • Head Replacement: If a damaged sprinkler head is the issue, the technician will remove and replace it. They’ll also check the surrounding components for damage to ensure everything functions properly.
  • Prevent Future Damage: If the damage was caused by external factors (e.g., construction or machinery), additional protective measures may be taken to avoid recurrence.
• Underground Leaks:
  • Excavation May Be Required: Underground leaks are often complex and can require excavation. The technician will locate the damaged pipes and repair or replace them.
  • Cost and Time Considerations: These repairs are more costly and time-consuming due to the need to dig and access the pipes.
• Frozen Pipes:
  • Thaw and Inspect: If the pipes have frozen, the technician will thaw them carefully to prevent cracking. After thawing, they’ll inspect the pipes for any damage. If cracks are found, the affected pipes will need to be replaced.
  • Prevent Freezing in the Future: If freezing is recurring, the technician may suggest insulating pipes or improving the system’s placement.
• System Replacements:
  • Complete Overhaul for Older Systems: In older sprinkler systems, the technician may recommend replacing larger sections of the system to ensure overall reliability. Extensive repairs may be necessary if the system has suffered from long-term neglect.
  • Long-Term Investment: While replacing large sections can be costly, it’s an investment in your building’s safety and can prevent future, more expensive repairs.

Prevent Future Fire Sprinkler Leaks

Preventing a fire sprinkler from leaking in the future requires regular maintenance and timely inspections. Here’s how you can protect your system:

• Routine Inspections: Schedule regular inspections per National Fire Protection Association (NFPA) 25 standards. This includes quarterly, annual, and five-year inspections to identify leaks or other problems early on.
• Regular Maintenance: Maintain your sprinkler system by cleaning, lubricating, and replacing worn-out parts. Proper maintenance ensures the system remains efficient and leak-free.
• Work with Professionals: Partner with a trusted fire protection company to ensure your system is regularly checked and maintained. Professional inspections can spot potential problems before they lead to leaks.
