Dry sprinklers should be retested at 10-year intervals to ensure their proper functionality and reliability in a fire protection system. This time frame is based on industry standards that recognize the potential for mechanical components to degrade or malfunction over time due to environmental factors or wear and tear.

Regular testing and maintenance are crucial because dry sprinklers are often used in environments susceptible to freezing, which can affect their performance. By conducting retests every 10 years, you help guarantee that the equipment is ready to operate effectively when needed, ensuring the safety and protection of a building and its occupants.

It is important to be aware of the relevant codes and standards, such as those outlined in NFPA (National Fire Protection Association) guidelines, which provide specific requirements for the inspection, testing, and maintenance of fire protection systems. Retesting intervals are established to balance the need for safety with practical considerations regarding system longevity and serviceability.
