What to Check During a Weekly Fire Pump Inspection

However well a sprinkler or hydrant network is designed, it only exists on paper if the pump that pushes the water fails to start. A scene that comes up again and again in the field looks like this: the pump room is locked, nobody is sure who has the key, the controller has been left in "manual" instead of "automatic", and there is no record anywhere of when the last check took place. A weekly fire pump inspection routine exists precisely to prevent that scene.

The weekly check does not replace annual maintenance. Its purpose is to catch faults early and confirm that the pump is ready to start automatically at any moment. A regular fifteen to twenty minute walk-through can reveal a closed valve or an empty fuel tank weeks before anyone would discover it during an actual fire.

In this article we go step by step through what to look at during the weekly check, in what order to work, which findings require immediate action and how to keep the record. What follows is a general framework; the pump manufacturer's manual and the instructions of the company that designed the system always take priority.

Why the Weekly Fire Pump Inspection Should Never Be Skipped

Fire pumps spend almost all of their life waiting. On a motor that has not run for a long time, packing can dry out, batteries can weaken, bearings can start to stick, or someone may close a valve during maintenance and forget to reopen it. What these faults have in common is that they stay silent until the moment the pump actually has to work.

The value of the weekly check lies in making these silent faults visible. Running the pump briefly and reading the basic gauges shows directly whether the system responds to a loss of pressure. If a fault develops in the gap between monthly or quarterly checks, the facility is effectively unprotected for that whole period; a weekly round narrows that gap.

The same logic applies to inspections. Turkey's Regulation on the Fire Protection of Buildings places responsibility on building management for keeping fire suppression systems in working order at all times and having them checked periodically. One of the first things requested during a fire brigade inspection or an insurance survey is a record showing that the pump is run regularly. If a check was done but not written down, from the inspector's point of view it was never done.

A common mistake is to treat the weekly check as "looking into the pump room and leaving". Seeing that the pump is still in its place proves nothing. The check only becomes meaningful when the pump is run, the pressures are read and the result is recorded.

Preparing Before the Check

Completing a few preparations before heading out both shortens the check and reduces the risk of false alarms. First, inform the facility's security desk or fire alarm control centre. When the pump runs, flow switches and pressure switches can trigger alarms; if this signal has not been announced in advance, it can lead to an unnecessary evacuation or a call to the fire brigade.

Next, look at the previous week's inspection form. If last week someone noted a leak, a low battery voltage or a pressure out of range, that point should be the first thing you check this week. Following the trend across records is the only way to notice that a value which looks normal on its own is actually getting worse week by week.

Take the following with you:

• The key to the pump room and the controller cabinet
• A blank weekly inspection form or the mobile device used for recording
• A torch, a clean cloth and, if needed, hearing protection
• The cut-in and cut-out pressure values taken from the pump manufacturer's manual

Finally, look at the pump room itself. It should be dry, clean and accessible. Using the pump room as storage, stacking material in front of the door or blocking the ventilation openings are frequent findings in the field and should always be written on the inspection form.

Visual Check of the Pump Room and Valves

The visual check done before running the pump makes the run test safe and meaningful. First, check the position of the main valves on the suction and discharge lines. These valves must be open and, where possible, secured in that position with a lock or seal. A closed or half-open valve means the pump can run and still fail to deliver water to the system.

Then confirm that the test and drain valves are closed and that there is no continuous water discharge from the relief and pressure relief valves. Look for drips, damp marks or rust stains on the pump casing, flange connections and pipework. On pumps with packing glands, a slight drip while running can be considered normal; water running continuously while the pump is stopped, however, may call for adjustment or replacement.

On the suction side, check the water tank level. If there is a level indicator, record the reading. A noticeable drop in tank level can be a sign of a leak in the system or a problem with the refill line.

An important point often missed at this stage is the temperature of the pump room. Especially in winter, pipes can freeze in unheated pump rooms and the diesel engine may struggle to start. If the room temperature is approaching freezing risk, note it as a separate finding and pass it on to the person responsible.

The Controller and the Electrical Side

The controller is the brain that allows the pump to start automatically. The first thing to check during the weekly round is that the controller is set to automatic. A controller left in manual after maintenance or testing is one of the most dangerous mistakes found in the field, because even a perfectly healthy pump will not start by itself when the pressure drops.

Next, check the indicator lights and display on the controller. The power-on light, phase sequence warning, fault lamps and any stored fault log should all be read. If a fault lamp is lit or an error code appears on the display, look up its meaning in the manufacturer's manual and record it. Brushing off a warning with "it has always been on" allows the problem to become permanent.

For electric motor driven pumps, an uninterrupted power supply is critical. The fire pump supply should be designed to remain live even when the building's general power is cut. During the weekly check, confirm that the controller has power and that the supply breaker is in the on position; also check whether there is a warning label to prevent the breaker from being switched off by mistake.

If there is a jockey pump, observe how often it runs. A jockey pump that starts and stops very frequently points to a small but continuous loss of pressure in the system. This may not be an emergency on its own, but over time it can cause the main pump to start unnecessarily and allow the leak to grow.

Additional Checks on Diesel Driven Pumps

Diesel driven fire pumps can run during a power cut, so many facilities use them as the standby or main pump. A diesel engine, however, has more check points than an electric pump, and each of them should be covered one by one in the weekly routine.

First, check the fuel tank level. The tank should be kept at a level that meets the running time foreseen by the manufacturer and the designer. A falling level may indicate not only fuel consumption but also a leak or unauthorised use. Check the fuel line for leaks and make sure the fuel valve is open.

Then move on to the batteries. The diesel engine depends on its batteries to start, and battery failure is one of the most common reasons diesel pumps fail to start. Check that the battery charger is working, that the voltage is within the normal range and that there is no corrosion on the terminals. Recording the voltage every week lets you notice a battery that is slowly weakening.

On the engine side, check the following:

• Engine oil level and any oil leaks
• Coolant level and hose connections
• Whether the block heater is working
• That the exhaust line is clear and intact
• Belt tension and any visible wear

While running the diesel pump, observe engine warm-up, oil pressure and speed. An engine that struggles to start, unusual exhaust smoke colour or an abnormal noise during running are all findings that must be recorded.

The Run Test Step by Step

The most important part of the weekly check is actually running the pump. To see whether the pump responds to a real pressure drop, the test should be as close as possible to an automatic start scenario. The method depends on the system design; for the exact procedure, follow the instructions of the design company and the manufacturer.

The general flow goes like this:

• First, record the system pressure at the start of the test.
• Then create a controlled pressure drop through the test valve or the pressure switch test arrangement.
• Read the pressure at which the pump starts and compare it with the value in the manual.
• While the pump runs, observe suction and discharge pressure, motor noise, vibration and the condition of the packing.
• Keep the pump running for the period recommended by the manufacturer; on diesel engines this period also covers the engine reaching operating temperature.
• Finally, stop the pump and make absolutely sure the controller is back in automatic.

If the pump's cut-in pressure during the test is clearly different from what is expected, the pressure switch setting or the sensing line should be checked. If the pump runs but the discharge pressure does not rise, this may point to a more serious problem such as air on the suction side, a closed valve or internal wear in the pump.

A common mistake is to start the pump using only the manual start button on the controller and consider the test done. That shows the motor turns, but it does not prove that the pressure switch and the automatic start chain work.

Which Findings Need Immediate Action?

Not every finding in the weekly check carries the same weight. To decide whether a finding should be handled immediately or during planned maintenance, the key question is: does this condition prevent the pump from starting automatically and delivering enough pressure during a fire?

Examples of findings that require immediate action:

• The pump does not start automatically
• One of the main valves on the suction or discharge line is found closed
• The diesel engine fails to start
• Battery voltage is clearly low or the charger is not working
• The fuel tank level cannot meet the design running time
• A persistent fault indication on the controller

If such a finding exists, it should be reported in writing to the facility manager and the system should be treated as out of service until the fault is fixed. Taking temporary measures while the pump is out of service, such as an additional fire watch, is the responsibility of the business, and that decision should also be recorded.

Findings such as a slightly increased drip from the packing, minor paint damage or disorder in the pump room can be handled during planned maintenance. They should still be written on the form and followed up; otherwise small findings can build up into a major failure.

How to Keep the Weekly Inspection Record

The record is the proof of the weekly check. A well-kept record makes inspections easier and shows the maintenance team when a fault began. A poorly kept record is nothing more than a list of signatures reading "checked" with no values in it.

Every weekly record should contain at least the following:

• Date and time of the check and the name of the person who did it
• Pump and facility details, with a separate line for each pump if there is more than one
• Starting pressure, the pressure at which the pump started and the discharge pressure while running
• For diesel pumps, fuel level, battery voltage and running time
• Confirmation that valve positions were checked
• Findings and the action taken
• Confirmation that the controller was returned to automatic at the end of the check

Writing down numerical values is far more useful than simply ticking "OK". Seeing how battery voltage changes over the weeks, or noticing that the cut-in pressure is drifting, is only possible when the numbers are recorded.

When records are kept on paper, forms get lost, become illegible or cannot be found at the time of an inspection. Keeping records digitally, together with photos and location data, both shows that the check really took place and makes it easy to search back through history.

Conclusion

The fire pump is the heart of the fire suppression system, and the weekly check is the most practical way to confirm that this heart keeps beating. Valve positions, the controller being in automatic, the fuel and battery condition of the diesel engine and a real run test are essential parts of every weekly round. Sorting findings by priority and recording them with numerical values turns the check from a formality into a genuine safety tool.
