Year-Round Fire Sprinkler Maintenance for Ohio Commercial Buildings

‍

Importance of Year-Round Sprinkler Maintenance

‍Fire sprinkler systems are one of the most critical safeguards in commercial buildings, but they require diligent year-round maintenance to remain effective. A well-maintained sprinkler system dramatically increases the likelihood of controlling a fire early, protecting lives and property. In fact, NFPA data shows that when sprinklers fail, a leading cause is lack of maintenance or closed valves. Routine inspections and tests throughout the year ensure that every component – from sprinkler heads to fire pumps – will operate correctly in an emergency. For building owners and safety managers, maintaining compliance with fire codes is not only a legal obligation but also a wise business decision that can reduce liability and insurance costs. In Ohio, these practices are especially important as the state’s fire code mandates adherence to national standards for sprinkler upkeep. By investing in regular maintenance all year, you safeguard your facility and gain peace of mind that your sprinkler system will perform when it’s needed most.

‍

NFPA Codes and Compliance

Several NFPA codes govern fire sprinkler systems, setting standards for installation and maintenance. The primary reference is NFPA 25 – Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems. NFPA 25 provides the minimum requirements for how often and in what manner sprinklers, valves, fire pumps, and related components must be inspected and tested to ensure they remain in working order. In Ohio, the Ohio Fire Code has adopted NFPA 25 by reference, meaning compliance with NFPA 25’s provisions is effectively required by law for commercial buildings.

Other relevant NFPA codes include NFPA 13 – Standard for the Installation of Sprinkler Systems (governing proper design and installation) and NFPA 20 – Standard for the Installation of Stationary Fire Pumps, which ensure systems are built to perform optimally. However, once your sprinkler system is installed and operational, NFPA 25 is the key standard that outlines the ongoing inspection, testing, and maintenance (ITM) tasks needed to keep the system compliant and ready. Adhering to NFPA 25 helps maximize system integrity and reliability, and it is used by fire marshals and insurance inspectors as the benchmark for sprinkler maintenance.

It's important to note that building owners are ultimately responsible for maintaining their fire protection systems in compliance with NFPA 25. Chapter 4 of NFPA 25 explicitly assigns the responsibility of all ITM activities to the property owner (or their designated representative). This means owners must ensure all required inspections and tests are conducted on schedule and that any problems are corrected promptly. Failing to do so can lead to non-compliance citations, increased fire risk, or voided insurance coverage. Fortunately, owners can delegate these duties to qualified professionals – which is where a trusted fire protection service partner comes in (more on that later). The key is that regular, code-compliant maintenance is not optional; it is a year-round commitment embedded in the fire codes and NFPA standards that Ohio abides by.

Routine Inspection and Testing Schedule

Fire sprinkler maintenance isn’t a once-a-year task – it’s an ongoing process with weekly, monthly, quarterly, annual, and multi-year activities as defined by NFPA 25. These routine checks and tests are designed to catch potential issues early and verify that all components will function during a fire emergency. Below is an overview of what needs to be done on a routine basis for a typical commercial sprinkler system:

• Weekly – Visual Inspections: On a weekly basis, conduct a quick visual check of the sprinkler control valves and critical gauges. Ensure all control valves are in the open position, properly locked or supervised, and free of any obstruction or tampering. In buildings with dry-pipe or deluge systems, verify that gauge pressures are normal (air and water pressures in the correct range). Also, walk the sprinkler riser room to confirm it’s secure, heated (to prevent freezing in winter), and nothing is leaking or visibly damaged. (Some industrial or high-hazard facilities may even require daily checks of specific items like fire pumps or gauges, but for most commercial systems weekly is the frequent cadence for visual inspections.)
• Monthly – Equipment Checks: Perform slightly more thorough inspections monthly. Wet pipe system gauges (which show water pressure) should be visually inspected to confirm normal pressure levels. Alarm valves (if your system has them) should be checked for any signs of leakage or trouble condition. In addition, inspect sprinkler heads from the floor to ensure they are not obstructed by dust, paint, or objects – they must have clear space to spray water effectively. Verify that nothing has changed in the environment that would block or damage heads (for example, new storage racks too close to sprinklers). NFPA 25 also expects building staff to ensure valve rooms and sprinkler areas are maintained at or above 40°F during cold weather to prevent freezing, so monthly checks of room thermometers or heat tracing systems in winter are critical in Ohio’s climate.
• Quarterly – Testing of Alarms and Water Flow: Each quarter, certain functional tests are required. A water flow alarm test should be conducted – this involves opening a test connection (often called the inspector’s test valve) to simulate a sprinkler activating and verifying that the water flow alarm bell or electronic signal operates correctly. Likewise, valve supervisory switches (tamper switches on control valves) need testing to ensure they send a trouble signal when a valve is shut. A main drain test is typically done quarterly as well, which involves briefly opening the main drain valve on the sprinkler riser to flush the pipe and record the water pressure drop; this test checks the water supply availability and that no obstructions exist in the pipes. During quarterly visits, inspectors will also review the hydraulic nameplate on the riser to ensure it’s legible and intact (the nameplate contains vital design info for the system).
• Annual – Comprehensive Inspection & Testing: The yearly inspection is a critical review of the entire sprinkler system. According to NFPA 25, all sprinkler heads must be inspected annually from the floor to ensure they are in good condition (not bent, corroded, painted, or obstructed). All exposed piping, fittings, hangers, and bracing are examined to verify nothing has been disturbed or deteriorated. The sprinkler system’s valves (control valves, check valves, etc.) should be exercised and lubricated to keep them in operable condition. An annual fire alarm connection test is performed (water flow and tamper switch tests, if not done quarterly, must be done annually at minimum). The back flow preventer (which prevents water from the sprinkler system from contaminating the city water) needs an annual test as well. Typically, a licensed back flow tester will perform a back flow forward-flow test to ensure adequate water can flow through for the sprinklers, as required by both NFPA 25 and plumbing codes. Annual service also includes checking the spare sprinkler stock: NFPA 25 requires keeping a stock of spare sprinkler heads and a wrench on site, and annually you must verify that you have the correct number and types of spare sprinklers available in case replacements are needed. After the annual inspection and tests, any deficiencies will be documented for repair, and an inspection tag is typically hung on the system per Ohio requirements, noting the date and who performed the work.
• Multi-Year Special Tests – Beyond the frequent routines above, NFPA 25 mandates several longer-interval tests to ensure the long-term integrity of the system. Every 5 years, an internal inspection of piping must be conducted to check for obstructive materials (e.g. sludge, scale, corrosion) inside the sprinkler pipes. If significant debris is found, a more comprehensive obstruction investigation and flushing will be performed. Sprinkler heads also have longevity limits: standard spray sprinklers must be laboratory tested or replaced at 50 years of service (and every 10 years thereafter), and quick-response sprinklers at 20 years (then every 10 years). These sample tests involve removing a representative sample of heads and sending them to a UL-certified lab for testing their functionality. Additionally, if your building has standpipe systems (manual hose connections for firefighters) or private fire hydrants on site, NFPA 25 includes 5-year flow testing requirements for those as well – ensuring adequate water flow and pressure is available. All of these periodic tests are critical for catching age-related deterioration that annual inspections might not visibly detect.

Sprinkler system risers with multiple control valves and gauges. Regular inspection of such equipment ensures valves remain open and free of tampering, gauges register normal pressures, and emergency signs or tags are intact. NFPA 25 mandates periodic visual inspections of sprinkler components to catch issues like closed valves or leaks before a fire occurs. Building staff should verify that nothing blocks or interferes with sprinkler heads (no paint, dust, or stock piled too high) as part of routine housekeeping, since obstructed or painted heads can delay or prevent proper activation during a fire.

Licensed Technicians vs. Internal Staff: Who Does What?

A common question building owners have is which maintenance tasks can their own facility team handle versus which require a licensed fire protection technician. NFPA 25 defines that all inspections, testing, and maintenance must be performed by qualified individuals – meaning someone who is trained, competent, and meets any certification requirements of the Authority Having Jurisdiction. In Ohio, this typically means that the more complex tests and any repair or alteration work must be done by state-certified fire protection contractors. Ohio’s regulations require companies and technicians to be certified to service, test, or repair fire sprinkler systems for hire. However, there are basic inspection activities that knowledgeable building personnel can carry out as part of their regular maintenance rounds. Let’s clarify the division of responsibilities:

• Owner/Facilities Staff (Unlicensed) – Building owners or in-house maintenance personnel can perform basic inspections and preventive upkeep that do not involve physically dismantling or altering the fire sprinkler system. For example, facility staff can do the weekly and monthly visual inspections noted earlier: checking that valves are open and accessible, gauges are in the correct range, and looking for any obvious leaks or damage. They can also record the readings of gauges, the room temperature in the pump room, and the condition of equipment as required – NFPA 25 actually requires the owner to maintain records of all such inspections. In many cases, owners will also conduct the weekly/monthly churn tests of electric fire pumps (running the pump without flow) if they have a trained individual on site, or at least run diesel pump engines briefly each week to keep them in shape (more on fire pump testing below). Essentially, routine observation and housekeeping – like keeping sprinkler control areas clear, ensuring adequate heat in sprinklered spaces, and reporting anything that looks amiss – can be handled by unlicensed staff as long as they are properly trained on what to look for. NFPA 25 expects that building owners will handle these frequent checks, and then call in professionals when a deeper expertise or corrective action is needed.
• Licensed Fire Protection Technicians – Certified professionals are required for the technical testing and maintenance tasks that go beyond simple inspection. As a rule of thumb, any activity that actually alters the state of the system or verifies performance likely needs a licensed technician. This includes annual and quarterly testing such as flowing water through test valves, trip-testing dry or deluge valves, performing main drain tests, and especially the annual full fire pump test. These procedures require specialized knowledge, can affect the system operation, and often must be coordinated with the fire alarm monitoring and local fire department. For example, an annual fire pump flow test involves running the pump under full load and flowing water out of the building – a complex procedure that must be conducted by qualified personnel for safety and accuracy. Similarly, opening a dry-pipe valve or deluge valve for a trip test will actually fill pipes with water or discharge sprinklers in a controlled manner; this is not something an untrained person should attempt. Repairs and maintenance tasks like replacing sprinkler heads, fixing pipe leaks, lubricating or rebuilding valves, or servicing fire pump controllers/motors absolutely fall under the scope of licensed technicians. In Ohio, any company performing such work for hire must hold a Fire Protection Contractor certification, and their technicians should have individual certifications or NICET credentials in sprinkler inspection and testing. Even when it comes to inspections: while an owner’s staff can note general observations, the official annual inspection report and tag must be completed by a qualified inspector who will sign off that the system meets code. This provides liability protection for the owner and assurance to authorities and insurers that a competent professional has evaluated the system. As NFPA 25 notes, the level of qualification should match the complexity of the task – “the qualification needed for looking at a gauge is not the same as that needed to perform an annual fire pump test”. Knowing these limits, smart owners use their internal team for frequent check-ups, but rely on licensed experts for thorough testing, problem diagnosis, and code-required certification of the system.

In summary, unlicensed (in-house) personnel can handle routine inspections and simple upkeep, while licensed technicians handle the formal testing, repairs, and any task that requires technical manipulation of the system. This collaborative approach ensures cost-effective maintenance – your staff can catch obvious issues early, and your fire safety contractor can perform the detailed work to keep the system in peak condition and code compliance. Always err on the side of safety: if there’s ever a doubt or an issue found, involve a professional. It’s better to be proactive and have a certified sprinkler technician correct a problem than to risk improper fixes that could lead to system failure.

Fire Pump Maintenance and Other System Components

If your building has a fire pump as part of the sprinkler system, maintaining this pump is as important as the sprinklers themselves. Fire pumps (governed by NFPA 20 for installation and NFPA 25 for maintenance) provide the necessary water pressure to sprinklers in taller or larger buildings, or in facilities where the water supply is not sufficient on its own. A fire pump that fails to start or perform can severely compromise your sprinkler system’s effectiveness in a fire, so regular pump inspections and testing are critical. NFPA 25 outlines specific fire pump test schedules depending on the type of pump:

Fire pump assembly in a commercial building, including the electric motor, controller, and piping. NFPA 25 requires regular testing of such pumps to ensure they will run and deliver adequate pressure when needed. For instance, diesel-driven fire pumps must undergo a no-flow “churn” test weekly, and most electric fire pumps must be tested monthly under no-flow conditions. During a churn test, the pump is run without discharging water, verifying that it starts automatically and runs without overheating. In addition, an annual full-flow performance test is conducted to measure the pump’s output at various flow rates (100% and 150% of rated capacity) to ensure it meets design pressure. These annual flow tests are rigorous and require qualified personnel in attendance to carry them out safely.

For electric fire pumps, NFPA 25 allows a monthly churn test in many cases, except where the pump is critical (for example, in very high-rise buildings or where the fire department connection can’t support the system). In those special cases, even electric pumps might need weekly testing. Diesel fire pumps, on the other hand, require weekly exercise without exception – not only to test the pump, but also to keep the diesel engine in good running condition (including checking oil pressure, engine temperature, battery charge, and fuel supply during the test). Every fire pump should also get a thorough annual maintenance service: changing engine oil and filters (for diesels), cleaning strainers, confirming the automatic start features, and calibrating pressure sensors in the controller. Pump rooms should be inspected frequently to ensure they are free of clutter, properly ventilated, and heated (at least 40°F to prevent the pump or pipes from freezing). Ohio’s climate makes pump room heating and generator block heaters (for diesel engines) very important in winter.

Beyond the pump, a complete fire sprinkler system has other components that need care. Back flow preventers, which are usually located near the sprinkler riser, must be tested annually to confirm they will allow full water flow to the system while preventing reverse flow. Typically, a back flow test is done concurrently with sprinkler service by a licensed tester. Standpipe systems (if present in high-rises or large facilities) require their own inspections – for example, hose connections should be inspected quarterly and a full flow test from the roof outlets every 5 years to ensure adequate pressure. Fire department connections (FDC) should be checked to make sure caps are in place and clapper valves function, so the fire department can boost your system if needed. All valves (including sectional control valves, alarm valves, and pressure-reducing valves) need periodic exercise to prevent seizure. If your system uses antifreeze loops (to protect small sections of pipe from freezing), NFPA 25 requires yearly testing of the antifreeze solution before the winter season to ensure it’s still at the proper concentration. Neglecting any one component can create a weak link in the chain; for instance, a closed sectional valve or a clogged back flow preventer can render your sprinklers useless despite all other sprinklers being in perfect shape. That’s why a holistic maintenance approach is important – a professional technician will check all aspects of the system (sprinklers, piping, valves, pump, back flow, etc.) during scheduled service visits to ensure nothing is overlooked.
