What should you ensure before flushing a standpipe system?

Before flushing a standpipe system, it is crucial to ensure that the water flow is clear. This step is essential because flushing the system effectively removes any debris, sediment, or foreign materials that may have accumulated within the pipes. Ensuring clear water flow not only safeguards the integrity of the water supply but also guarantees that the standpipe will function properly in the event of a fire emergency. If the water flow is obstructed or contaminated, it could hinder the system’s performance, potentially leading to failed fire suppression when it is needed most.

While other factors like system pressure, connection to the main supply, and fire department approval are important for overall system readiness and compliance, they do not directly address the immediate need to maintain a clean and functional water flow within the standpipe for optimal operation.
