Fire sprinkler systems are one of the most critical components of fire protection in commercial, and industrial settings. However, as highlighted in Elite Fire Protection’s blog last month, ensuring their effectiveness depends heavily on proper maintenance. Unfortunately, several myths surround the maintenance of these lifesaving systems, often leading to neglect or improper care. Let’s help with setting the record straight by debunking the top myths in fire sprinkler maintenance, with a focus on the South African context.
Myth #1:
Fire Sprinkler Systems Don’t Need Maintenance
Many property owners assume that once a sprinkler system is installed, it will function flawlessly forever without any upkeep.
The reality: Regular maintenance is essential to ensure the system remains in optimal working condition. Over time, sprinkler heads can become clogged with dust or debris, and pipes may corrode, especially in areas with hard water like Johannesburg and Pretoria. Longevity is also dependent on the nature of business, for example sugar mills have issues with sugar dust that very quickly clog valves, fire sprinklers and corrode piping. South African regulations, such as SANS 10287, mandate routine inspections and maintenance by competent person(s) to keep systems compliant and effective. The competent person(s) shall provide the occupant with a signed, dated report of the inspection and advise him of any corrective action implemented or needed.
Myth #2:
Maintenance Is Only Required After Activation
Some believe that fire sprinkler systems only need attention if they have been activated during a fire.
The reality: Even if a sprinkler system has never been activated, it still requires periodic testing and inspection. Components like valves, pressure gauges, and sprinkler heads must be checked regularly to ensure they are functioning correctly. Neglecting these checks could lead to system malfunction when it is needed most.
Myth #3:
Corrosion Isn’t a Problem in Sprinkler Systems
It is often assumed that sprinkler system pipes are immune to corrosion.
The reality: Corrosion is a significant concern, especially in areas with varying water quality. In a recent case study, Elite Fire Protection was able to demonstrate corrosion in a section of piping, in a more than 25 year old fire sprinkler system. Over time, rust and scale can build up inside pipes, reducing water flow and potentially causing leaks. Special coatings and internal pipe treatments can help mitigate corrosion, but regular maintenance is still vital to identify and address issues early.
Myth #4:
Anyone Can Perform Maintenance on Fire Sprinklers
To save costs, some property owners believe they can handle sprinkler maintenance themselves.
The reality: Fire sprinkler maintenance requires specialized knowledge and equipment. In South Africa, only qualified professionals certified under relevant standards should perform inspections and repairs. Attempting DIY maintenance can lead to improper servicing and void insurance coverage.
Myth #5:
Sprinkler Systems Are Always Visible and Easy to Inspect
The assumption that all components of a sprinkler system are easily accessible is widespread.
The reality: Many systems have concealed components, such as pipes running behind walls or above ceilings. These hidden parts must be inspected using specialized tools and techniques. Professional technicians have the expertise to identify potential issues in hard-to-reach areas.
Myth #6:
Fire Sprinklers Don’t Need Testing Unless There’s a Problem
Some property owners think that as long as the system hasn’t shown any visible issues, it doesn’t need testing.
The reality: Routine testing is crucial to confirm the system’s functionality. Flow tests, for example, ensure adequate water pressure, while alarm tests verify that the system communicates correctly with fire control centres. Neglecting these tests could result in critical failures during an emergency.
Myth #7:
Heads Never Need Replacement
There’s a belief that sprinkler heads are built to last indefinitely.
The reality: Sprinkler heads have a finite lifespan and can degrade over time due to environmental factors such as dust, heat, and humidity, and in the case of a sugar mill, sugar dust. In South Africa, it’s recommended to test and replace sprinkler heads every 25 years or sooner if signs of wear and tear are detected during inspections.
Myth #8:
Maintenance Is Too Expensive
Cost is a common reason cited for skipping regular sprinkler maintenance.
The reality: While there are costs associated with professional maintenance, these are minor compared to the expenses of repairing fire damage, facing non-compliance penalties or declines with insurance claims. Ask your insurance provider if they offer discounts on premiums for well-maintained fire protection systems, to further offset maintenance costs.
Myth #9:
Water Supply Is Always Reliable
It is assumed that as long as a sprinkler system is connected to the water supply, it will work without issues.
The reality: Water supply interruptions or pressure drops can compromise a sprinkler system. Regular testing ensures that backup water supplies, such as tanks or pumps, are operational. This is particularly important in areas with inconsistent water supply, such as parts of Gauteng and Limpopo.
Conclusion
Fire sprinkler maintenance is not a task to overlook or underestimate. By debunking these common myths, South African property owners can better understand the importance of regular upkeep to ensure their fire sprinkler systems perform when needed most. Whether you manage a warehouse in Pretoria, an office in Sandton, or a shopping mall in Johannesburg, investing in professional sprinkler maintenance is a proactive step toward safeguarding lives and property. Don’t let misinformation jeopardize your fire safety priorities. Schedule your system’s next inspection today!
