What is the function of a standpipe's test connection?

• A. For testing water supply pressure and flow
• B. For drainage testing
• C. For venting air only
• D. For electrical grounding

Answer: (A)

The standpipe’s test connection is there to measure how much water pressure and flow the standpipe can deliver. When you’re performing acceptance or hydrostatic testing, you attach a pressure gauge and, if needed, a flow-testing device to this dedicated connection. This lets you verify that the water supply can reach the required pressure at the design flow, confirming the system will perform correctly when firefighters open outlets. It isn’t used for drainage testing, venting air alone, or electrical grounding, which are separate functions and tests.
