The fire pump group is the single point that supplies all water extinguishing systems in the building: the sprinkler system, the hydrant system, and the fire cabinet all draw water from the same pump. If the pump fails to operate, none of them will operate. Nevertheless, the pump room is the area that is found to be the most difficult to maintain and the most neglected — because it requires both mechanical and electrical knowledge simultaneously.
We provide periodic inspection, function testing, performance measurement, troubleshooting, and commissioning services for electric, diesel, and jockey pump units. We understand that finding a company to maintain sprinkler, hydrant, and fire pump units is difficult; this is one of the services ASPEK regularly performs.
Why Is a Fire Pump Unit a Separate Specialty?
A fire pump unit is not a single machine but a system that must work together: main pump (electric or diesel), standby pump, pressure-maintaining jockey pump, each with its own control panel, pressure switches, suction and discharge line valves, check valves, test line, expansion tank, and water reservoir. Each of these can individually be sound and the system still may not function; because what determines operation is how these components interact with each otherA zone monitoring module connects an entire conventional detector line to the addressable loop. Critical areas are renewed with addressable devices while secondary zones continue to operate with their existing wiring. This provides significant cost advantage in capacity upgrade and renovation projects.
This is why pump room maintenance is neither purely mechanical nor purely electrical work. The setting of the pressure switch, the automatic/manual position of the panel, the battery and charging circuit of the diesel engine, the leakage of the check valve — the fault emerges at the intersection of these two disciplines. The reason there are few companies in the market performing both aspects together is this.
What Is Included in Maintenance?
Checks performed at each visit
- Pump room temperature, ventilation, drainage, and lighting
- All valves in correct position and positions kept locked/sealed
- Reading suction and discharge line pressures, comparing with design values
- Water reservoir level, automatic water feed, and level alarm verification
- Warning lamps on the panel, position switches, and alarm outputs verification
- Coupling, foundation connections, and observation of vibration/heat
Automatic startup test
is the most critical item of maintenance and must not be confused with manual operation. Pressure from the test line is reduced in stages and the pump's automatic startup from its own pressure switch is expected. During this:
- Each pump's startup pressure is measured separately (jockey at the top, main pump in the middle, standby pump at the bottom)
- The pump's startup time is monitored
- Not automatic shutdown, but continued running behavior is verified — the fire pump must not stop on its own
- Remote alarm and monitoring signals are verified to reach the fire panel
Specific to diesel pump
- Battery voltage, electrolyte level, terminal cleanliness, and verification that the charging circuit is actually charging measurement
- Initial startup attempt separately from each battery bank
- Fuel level, fuel quality, water/sediment drainage, and air in fuel line verification
- Engine oil, cooling water, belt tension, exhaust line, and muffler
- Monitoring engine speed, temperature, and oil pressure while running under load
In diesel pumps, the most common problem we encounter in the field is not the engine itself; it is degraded fuel and uncharged battery. A motor run for only a few minutes per year will have its fuel degrade over time, and if the charging circuit is faulty, the battery will discharge even while connected to the mains. Both progress silently while the system appears "ready".
Annual performance test
The pump must not only run, but must actually deliver the design flow rate and pressure . By measuring flow through the test line, the pump's head–flow curve is verified; measurements are taken at zero flow, design flow, and excess flow points. Over the years, due to impeller wear, a clogged suction strainer, or a closed valve, the pump may appear to run while remaining below design values. This is visible only through measurement.
How Is the Interval Determined?
BYKHY Article 100 does not specify a separate frequency for the pump unit; it defers to the standard governing the system. In wet sprinkler systems, this standard is TS EN 12845and defines weekly, monthly, quarterly, annual, and longer-interval tasks in stages. To this is added the pump and motor manufacturer's own maintenance manual. In practice, the program we establish follows this logic:
- Frequent and brief checks — valve positions, pressures, water level, automatic operation test
- Medium-interval tasks — diesel engine running under load, battery and charging circuit measurement
- Annual tasks — performance test with flow measurement, complete panel function verification, mechanical wear assessment
It is common and reasonable for building managers to have their technical staff perform weekly checks and leave periodic measurements and tests to us; in this case we establish the record format together.
Why Should You Procure This Service from a Single Firm?
Fire safety is not a single system, but two interdependent engineering disciplines: mechanical side (pump unit, sprinkler, hydrant, fire cabinet, piping) and electronic side (detection, alarm, announcement, suppression triggering, control panels). Few firms in the market perform both sides together; most facilities obtain mechanical maintenance from one firm and electronic maintenance from another.
The problem starts here. What activates the system during a fire is not individual devices, but the connections between them: the flow switch will alert the panel, the panel will trigger the pump and damper, the announcement will sound before the gas system discharges, the elevator will descend to the evacuation floor. If there is a gap in responsibility between two firms in the middle of this chain, both firms may hand over their equipment as "working" while the system as a whole does not function. The most frequent fault we observe in the field is not a defective device, but an interface that no one ownsA zone monitoring module connects an entire conventional detector line to the addressable loop. Critical areas are renewed with addressable devices while secondary zones continue to operate with their existing wiring. This provides significant cost advantage in capacity upgrade and renovation projects.
As ASPEK Mühendislik, we are headquartered in Ankara and serve throughout Turkey. We conduct mechanical and electronic maintenance within the same team schedule; the installation, filling, and maintenance of sprinkler, hydrant, and fire pump units and FM-200 and Novec 1230 gas suppression systems fall within this scope — areas where finding a qualified technician is most difficult.
We structure our scope accordingly: from detection to gas suppression, from sprinkler and hydrant lines to fire pump units we provide end-to-end end to end in a building — single contract, single point of contact, single reporting format. For facilities that request it, we also add the periodic maintenance of camera (CCTV) systems to the same contract; when fire and security infrastructure is consolidated under one roof, there is no such thing as a "fault falling between two firms."
Legal Basis for This Maintenance
Regulation on Fire Protection of Buildings (BYKHY) maintenance of fire safety systems is defined not as an optional improvement, but as an obligation incumbent upon the building owner and administrator defines it as follows:
- Article 84 — Emergency lighting, signage, and fire detection and alarm systems shall be subject to periodic inspection, testing, and maintenance as required by the system specified in the applicable standards, under the responsibility of the building owner and administrator or the building official to whom they have delegated responsibilities in writing.
- Article 100 — Fire suppression systems shall be subject to periodic inspection, testing, and maintenance as required by the system specified in the applicable standards, under the responsibility of the building owner, administrator, or the building official to whom they have delegated responsibilities in writing is a requirementA zone monitoring module connects an entire conventional detector line to the addressable loop. Critical areas are renewed with addressable devices while secondary zones continue to operate with their existing wiring. This provides significant cost advantage in capacity upgrade and renovation projects.
The common aspect of both articles is this: the regulation does not prescribe the period itself, but refers it to the standard the system is subject to. In other words, maintenance frequency is set not by the regulation but by the standard the system was designed to (TS EN 12845 for sprinklers, the TS EN 54 series for detection, TS ISO 14520 for gas systems) and by the manufacturer's own manual. A specification that says "the regulation requires this frequency" is built on the wrong basis.
The Ministry's regulation guide explicitly requires retention of these records: information, documents, and records related to inspections, maintenance, and tests must be kept in a secure place by the building owner, administrator, or responsible party for submission to relevant authorities in any emergency. Maintenance being performed is not enough; it must be documented that it was performed.

To Set Up Your Maintenance Program
One contract, a solution for everything: we provide end-to-end maintenance to fire detection, gas suppression, sprinkler, hydrant, and pump units in their entirety; if you wish, maintenance of camera (CCTV) systems can also be added to the same contract.
If you do not have the brand, age, and last maintenance record of the existing system on hand, that is not a problem; the first step is anyway inventory and current condition assessment. Setting up an annual program without seeing what is there in the field means selling maintenance for a system that does not exist.

Frequently Asked Questions
How frequently should a fire pump be tested?
BYKHY Article 100 does not specify the frequency itself, but refers to the standard to which the system is subject; for water suppression systems, this is TS EN 12845. The standard defines a tiered program ranging from weekly to annual intervals, supplemented by the maintenance manual of the motor and pump manufacturer.
Does manual operation of the pump from the panel count as a test?
No. Manual operation only shows that the motor turns. The actual test is when the pump automatically activates via its pressure switch as pressure drops from the test line. The most common fault we find in the field is a pump that operates manually but does not activate automatically.
Is it normal if the jockey pump activates continuously?
No, it is not normal. The jockey pump's function is to compensate for minor pressure drops in the line; if it runs continuously, there is either a leak in the line, a valve or check valve bypass, or incorrect pressure setting. This condition can also delay the main pump from activating when necessary.
What is the most common fault in diesel fire pumps?
Not the motor itself, but the battery and fuel. If the charging circuit is faulty, the battery depletes even when connected to mains power; in infrequently operated engines, fuel deteriorates over time. Both conditions progress while the system appears ready and only emerge at the first start attempt.
Do you service pumps from brands such as Etna and Clarke?
Pump group maintenance is performed independently of brand; the determining factors are the pump type, drive method (electric/diesel), and control panel configuration. Before maintenance, an inventory assessment clarifies the existing group's brand, model, and spare parts status.
The pump is running but there is insufficient pressure—what could be the cause?
The most common causes are a clogged suction filter, a partially closed suction valve, check valve leakage, impeller wear, and air in the suction line. Which one it is can only be determined by flow-measured performance testing; visual inspection alone will not reveal it.
Who can perform fire pump maintenance?
A pump group is both a mechanical and electrical system: diesel motor, battery and charging rectifier, control panel, jockey pump pressure settings. For this reason, a single-discipline service is insufficient; a team knowledgeable in both fields is required. ASPEK's mechanical and electrical staff perform the circulation test, check pressure switches, and address faults on site during the same visit; we travel from Ankara to facilities throughout Turkey.
Can the maintenance company also perform the periodic inspection?
Yes; flow-pressure testing, control of automatic activation pressures, and reporting are performed by us. If your facility requests independent inspection, this distinction is important: a Type A inspection body cannot remedy deficiencies it finds due to impartiality requirements. We are both the maintenance party and the party that remedies deficiencies found in the inspection report and prepares the system for retesting.
What document is provided after maintenance, and is it valid for inspection?
We provide a measured maintenance report containing the activation pressures, operating times, battery and fuel status, and flow-pressure test values for the jockey, electric, and diesel pump. Test items required by TS EN 12845 are entered in the report; it serves as a record for fire department inspection and insurance files. For multi-location companies, we provide centralized reporting for pump rooms throughout Turkey.
What happens if I do not perform maintenance?
The pump is the heart of the sprinkler and hydrant line; if the pump does not start, the water in the pipe serves no purpose. The most common faults we encounter in the field are small, not large ones: depleted battery, empty fuel tank, suction valve left closed. BYKHY places the responsibility on management to keep the system operational; pump failure to activate in a fire means both loss of life and legal liability.
Does the insurance company request pump test records?
For facilities with water suppression systems, the request for pump test and maintenance records following damage is common practice; a record of regular circulation testing is effectively expected. Terms vary from policy to policy, and we do not make definitive statements; however, we clearly observe that the process progresses significantly more smoothly for facilities that maintain regular test records.
