What is the minimum flow rate for a manual standpipe system during the flow test?

Explanation:
Flow testing a manual standpipe is about confirming the system can deliver a sustained, adequate water flow for firefighting. The standard specifies a minimum flow rate of 250 gallons per minute to be demonstrated during the test. This rate reflects the typical demand of a single handline (such as a 2 1/2-inch hose) and allows the system to show it can overcome the piping losses and still deliver usable pressure at the outlet. If the test flow were lower, it wouldn’t prove the standpipe can support normal firefighting operations; higher flows aren’t required for the basic test. So, the minimum flow rate used in the flow test is 250 gpm.
