How often should a fire protection water storage tank serving a warehouse have its level indicator tested?

The level indicator of a fire protection water storage tank serving a warehouse should be tested annually to ensure it is functioning correctly and providing accurate readings. Regular testing is crucial because it helps to verify the reliability of the water supply, which is essential for fire suppression systems to operate effectively in an emergency. If the level indicator is not functioning properly, it might lead to a false sense of security regarding the availability of water for firefighting purposes.

Annual testing aligns with standard maintenance practices as it strikes a balance between frequency and thorough oversight. Testing it more than once a year, such as monthly or quarterly, may not be necessary for many facilities unless the specific conditions of the tank suggest a higher potential for malfunction. Thus, the annual requirement provides a systematic approach to maintenance without undue burden, thereby ensuring both safety and operational efficiency in fire protection systems.
