How frequently should sprinkler systems be serviced?

Sprinkler systems should be serviced annually to ensure they are functioning correctly and maintaining the necessary protection against fire hazards. Regular servicing involves checking for issues such as leaks, corrosion, and ensuring that all components are working as intended. This annual inspection is typically mandated by fire codes and insurance requirements because it helps to ensure that the system will operate effectively in the event of a fire.

In addition to the general annual maintenance, some components, like fire pumps or special hazards, may require more frequent inspections. However, the standard requirement for most sprinkler systems remains an annual service. This helps in identifying potential issues before they become critical problems that could impede the system's performance in an emergency situation.
