Inspecting sprinkler systems is a key component of preventive fire protection. Only if your system is regularly inspected and maintained can you be sure that it will activate reliably in an emergency and provide an adequate supply of water for fire suppression.
In addition to legal requirements set forth in DIN EN 12845, VdS CEA 4001, and insurance regulations, one thing is of paramount importance: ensuring that your sprinkler system remains operational at all times.
Why is regular inspection of sprinkler systems so important?
A sprinkler system operates in the background—often unnoticed for years. However, corrosion, pressure losses, hidden leaks, or technical defects can impair its function. Without regular inspections of sprinkler systems, such defects often go undetected.
The consequences can be serious:
Delayed or failed activation in the event of a fire
Insufficient water pressure
Loss of insurance coverage
Liability risks for operators
Regulatory requirements or shutdown
A professional inspection ensures that all components—from the alarm valve station to the piping and sprinkler heads—function properly. At the same time, it extends the system’s service life and reduces costly damage.
What are the inspection intervals for sprinkler systems?
The inspection intervals for sprinkler systems are clearly regulated and are based on standards, manufacturer specifications, and insurance requirements.

Depending on the hazard class and type of property, additional inspections may be required. Comprehensive documentation is crucial—it serves as proof for authorities and insurers.
Side Note: What Are the Responsibilities of the Sprinkler System Supervisor?
An important part of inspecting sprinkler systems is the role of the so-called sprinkler inspector. This person is appointed by the operator and performs regular visual and functional checks. However, the sprinkler inspector does not replace a certified specialist company. Rather, they complement regular professional maintenance.
You can find detailed information on the duties, responsibilities, and training requirements in our separate article on the sprinkler system inspector.
Inspection of Pumps, Tanks, and Power Units
A comprehensive inspection of sprinkler systems also includes checking the underlying technical infrastructure—in particular:
-
Diesel and electric pumps
-
Firewater tanks
-
Emergency power generators
These components ensure that, in the event of a fire, sufficient firefighting water is available at the required pressure—even during a power outage. Maintenance includes, for example, test runs of diesel pumps to ensure proper starting and operational readiness. In addition, the fuel supply and batteries are checked, as they are crucial for reliable pump startup. The tanks are also inspected for corrosion or deposits to ensure the firewater supply is not compromised. Finally, performance tests are conducted on the pump system to verify that the flow rate and pressure match the target values.
A detailed overview of the scope of maintenance, standards, and modern testing methods (e.g., tank inspection using an underwater drone) can be found in a separate blog post.
