Every five years, fire sprinkler systems must undergo mandatory fire sprinkler 5-year testing and inspection, and fire department connection (FDC) hydrostatic testing during the annual test and inspection as per NFPA 25 13.8.5. This includes everything from your annual inspection, and adds that the piping form the FDC and the fire department check valve is hydrostatically tested. The internal condition of piping for the fire sprinkler system is also assessed as per NFPA 25 14.2
These tests are crucial, as they give you the ability to potentially identify failure points on the fire sprinkler systems that are not identifiable from standard annual fire sprinkler testing and inspections. Here, we outline each part of this five-year test.
Visual Fire Sprinkler Inspection With Disassembly
A certified technician will conduct a thorough inspection of all the components of your fire sprinkler system. This includes inspecting the internal condition of the piping to make sure there is no foreign material, signs of microbiologically influenced corrosion (MIC), or other build-up that naturally occurs and could potentially cause blockages or the under performance of the fire sprinkler system.
The internal pipe inspections involve disassembling each sprinkler zone at specific points to verify conditions and based on the results we will make recommendations or confirm that the systems are in good or reasonable working condition. The disassembly zone points are at every other sprinkler zone, and include the main line, branch lines, system riser, and cross main.
The technician will also inspect fittings, sprinkler heads, valves, alarms, and any other associated equipment! For example, every sprinkler head is visually inspected to ensure they’re free from damage, corrosion, or blockages that could impair water flow.
Hydrostatic Test
The piping from the FDC and fire department check valve itself must be hydrostatically tested at 150 PSI for a period of two hours. This involves pressurizing this system with water to ensure that it can withstand the required water pressure without leaking or failing. During this test, water is pumped at a higher pressure than designed to simulate conditions that might be encountered during a fire emergency.
This test helps ensure compliance and structural integrity, as well as checking for corrosion or degradation.
The inspector will also conduct testing included in an annual inspection outlined below.
What Happens After A Fire Sprinkler 5-Year Testing?
Detailed records of the inspection and testing procedures are made and delivered for you to maintain. These records are important for compliance, insurance, and ensuring the system is working properly to keep your property and people safe.
If any deficiencies or issues are found during the 5-year fire sprinkler test and inspection, they must be promptly repaired and corrected. This can include repairing or replacing any damaged components, cleaning or flushing the system, and ensuring that all elements meet the current fire safety standards. We always send a quote for your approval when repairs need to be made and deficiencies need to be corrected!
Because It Matters
A 5-year inspection is crucial for preventative maintenance (and required per NFPA 25) as it gives you the ability to potentially identify failure points on the fire sprinkler systems that are not identifiable during or part of standard testing and inspections. By ensuring your fire sprinkler system is up to standards, Integrity Fire helps ensure the safety of your people and your property. Reach out today and get started on your testing & inspection.
