How often are standpipes typically flowed for maintenance checks?

Standpipes are typically flowed for maintenance checks every five years to ensure they are functioning properly and to identify any potential issues that may need to be addressed. This interval allows enough time to evaluate the system effectively while adhering to industry standards and regulations. During these checks, the flow rate is tested to confirm that the standpipe system can deliver the required amount of water, and it provides an opportunity to inspect the components for wear and tear.

While annual checks may be necessary for other aspects of the fire protection system, standpipe flow tests are mandated less frequently. This is due to the robust nature of the equipment when properly maintained and the lower risk of deterioration compared to systems that are more frequently used or exposed to the elements. Flow testing every five years strikes a balance between ensuring operational readiness and managing maintenance resources effectively.
