Preassembled fire sprinkler riser assemblies can reduce field labor, simplify installation, conserve mechanical room space, and create a more consistent layout for inspection, testing, and maintenance. By combining multiple sprinkler system components into a factory-assembled, tested unit, contractors can reduce the piping, fittings, and assembly required in the field. AGF Manufacturing’s

RiserPACK® assemblies integrate key fire sprinkler system components into compact configurations designed for NFPA 13, NFPA 13R, and NFPA 13D applications.

Key Takeaways

Preassembled fire sprinkler riser assemblies can:

• • • Reduce field fabrication and installation time
    • Reduce the number of field connections and potential leak points
    • Create more compact and consistent sprinkler system layouts
    • Simplify access for inspection, testing, and maintenance
    • Integrate testing, draining, pressure monitoring, and other required functions
    • Reduce the number of individual components contractors need to source and assemble

Fire sprinkler systems are designed to protect lives and property when seconds matter. But even the best designed system depends on regular inspection, testing, and maintenance to remain ready for service.

That is where NFPA 25 comes in.

NFPA 25, Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems, establishes the baseline requirements for maintaining water-based fire protection systems after installation. It provides guidance for inspecting, testing, and maintaining systems and components so they continue to operate as intended.

For contractors, inspectors, facility teams, and building owners, NFPA 25 is more than a checklist. It is an ongoing service framework that helps identify issues before they become failures and helps owners meet applicable code, inspection, and documentation expectations. Most importantly, it helps ensure fire protection systems are ready when needed.

AGF products are commonly used in areas of a sprinkler system that require regular inspection, testing, and maintenance. Understanding those requirements helps contractors service systems more effectively and helps owners maintain safer, more compliant buildings.

Test and Drain Requirements

As the name suggests, TESTanDRAIN and Inspector’sTEST valves play an important role in confirming system readiness. They are used to verify waterflow alarm operation, support draining procedures, and help confirm that water supply performance has not degraded over time.

Main drain tests should be performed at the frequency required for the system arrangement and water supply configuration. The test valve should be in an accessible location, downstream of the waterflow alarm, and the drain should be discharged to a location that will not cause damage.

NFPA 25, Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems, establishes the minimum requirements to ensure that fire protection systems remain operational and effective over time. The standard is performance-based in its intent, requiring ongoing inspection, testing, and maintenance (ITM) to verify that system components function as designed.

A critical point emphasized within NFPA 25 is that the responsibility for compliance rests with the building owner or designated representative. The owner is responsible for ensuring that required ITM activities are performed, deficiencies are corrected, and records are maintained (NFPA 25, 2023, §4.1.1; §4.3). Contractors and inspectors perform the work, but compliance accountability remains with the owner.

The inspector’s test valve is a vital component of any wet fire sprinkler system. At the heart of this connection is the test orifice. A small but critical feature that certifies the system’s waterflow alarm functions correctly. Both NFPA 13 (Installation of Sprinkler Systems) and NFPA 25 (Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems) provide requirements that govern the size, purpose, and functionality of this orifice.

A proactive approach to extend the life of your systems.

Among the requirements needed to keep commercial fire sprinklers working and code compliant are the routine inspections, which can seem complex. Most of the Inspection, Testing and Maintenance (ITM) of sprinkler systems require a qualified life safety professional, but some of the work can be done by in-house facility personnel.

NFPA 25, the Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems is the primary standard for most facilities and this standard assign specific responsibilities to the property owner or their designated representative. The property owner is ultimately responsible for the integrity of the fire sprinkler system even if ITM is being provided by an outside contractor.

4.1.1 Responsibility for Inspection, Testing, Maintenance, and Impairment. – The property owner or designated representative shall be responsible for properly maintaining a water-based fire protection system.
