How often should water storage tank level indicators be tested for accuracy?

Water storage tank level indicators, which are critical for maintaining proper water levels in fire suppression systems and ensuring operational readiness, should be tested for accuracy every 5 years. This time frame allows for regular monitoring while acknowledging that these devices are generally designed for durability and longevity. The 5-year interval strikes a balance between sufficient oversight and practical maintenance schedules, ensuring that any potential inaccuracies in the level readings are detected and corrected before they can cause operational issues or compromise safety systems.

Testing at this interval ensures that the indicators are functioning correctly and providing reliable data, which is essential for effective fire protection measures. Regular maintenance and testing help to prevent any failures that could lead to inadequate water supply during emergencies. In contrast, more frequent testing, such as annually or bi-annually, could be unnecessarily burdensome and may not yield significantly different results regarding the accuracy of the devices. Therefore, the 5-year requirement is based on industry standards that focus on practicality while maintaining safety and effectiveness in fire sprinkler system operation.
