How many years of service must sprinklers be replaced or tested?

Sprinklers must be replaced or tested every 50 years as a standard practice to ensure their continued effectiveness and reliability in fire protection systems. This timeframe is based on the understanding that over time, environmental factors, corrosion, and other conditions can impact the functionality of the sprinkler heads. Regular testing and replacement after 50 years help maintain compliance with safety standards and ensure optimal performance in the event of a fire. This extended duration reflects the durable design and materials used in modern sprinkler systems, which are intended to last for several decades if properly maintained.
