A fire sprinkler system leak can mean potential property damage, compromised safety measures, and increased risks of fire hazards. Learn what causes leaks and what to do if your system springs a leak. 

Your fire sprinkler system should only dispense water to put out a fire. But, leaks are going to happen. When they do, it’s vital for the safety of your property and everyone inside to have a professional sprinkler contractor like DynaFire inspect your system right away. 

One issue with fire sprinkler system leaks is that they aren’t always as evident as a “drip, drip, drip” coming from your pipes. You always need a professional team to identify leaks that may go unnoticed. Now, let’s review some common causes of leaks, how leaks are detected, and strategies to prevent them.

Common Causes of Fire Sprinkler System Leaks

Fire sprinkler systems are critical to building safety, but leaks pose significant risks. Understanding the common causes of fire sprinkler leaks can help you get ahead of a potential fire hazard and prevent costly damage to your property.

Common causes of fire sprinkler leaks include:

• Corrosion and Rust – Over time, corrosion and rust can weaken the integrity of fire sprinkler pipes, leading to leaks.
• Freezing Temperatures – Exposing wet pipe systems to freezing temperatures can cause them to expand and contract, resulting in cracks and leaks.
• Mechanical Damage – Physical damage to fire sprinkler components, such as accidental impact or improper handling during maintenance, can cause leaks.
• Manufacturing Defects – Defects in the manufacturing process of fire sprinkler components may lead to vulnerabilities that result in leaks.
• Water Pressure Issues – Fluctuations in water pressure can stress fire sprinkler pipes and fittings, leading to leaks.
• Improper Installation: Poor installation practices, such as inadequate sealing or incorrect pipe alignment, can cause a fire sprinkler system leak.
• Corrosive Environments – Exposure to corrosive substances or environments can accelerate the deterioration of fire sprinkler pipes and fittings, resulting in leaks.
• Aging Infrastructure – Fire sprinkler systems installed in older buildings may experience deterioration over time, increasing the likelihood of leaks.
• Lack of Maintenance: Neglecting routine maintenance and inspections of fire sprinkler systems can allow issues to go undetected and lead to leaks.

What Should You Do If You See Or Suspect A Leak?

When you notice a leak in your fire sprinkler system, it’s crucial to act swiftly. Follow these steps to get your system back in order quickly and safely.

Step #1: Start by determining the cause of the leak and assess whether evacuation is necessary. Leaks in fire sprinkler systems can lead to electrical issues and even the risk of fire ignition.

Step #2: If you observe a significant amount of water flowing out, shut off the water supply immediately to prevent further damage. Even if the leak seems minor, conduct a thorough inspection of pressure gauges to check for any additional leaks within the piping network.

Step #3: Once you’ve investigated the source of the leak and, if required, evacuated the premises and shut off the water supply, it’s time to contact your fire sprinkler company.

Provide them with detailed information about the leak to ensure prompt and effective resolution. Remember, addressing leaks right away is crucial to maintaining the safety and integrity of your property.

Can Fire Sprinkler System Leaks Be Avoided?

Most (but not all) fire sprinkler leaks can be avoided by hiring a professional fire sprinkler company to conduct thorough inspections for comprehensive leak detection. These experts have the skills and tools necessary to identify leaks that may not be obvious to the untrained eye. Annual inspections of your fire sprinkler system are required under NFPA 25, and adhering to a regular schedule can help prevent damage resulting from leaks.
