Following completion of discharge of foam solution to the hazards protected, foam-water sprinkler and spray systems shall discharge water until what occurs?

Explanation:
The system keeps delivering water to purge and rinse the lines after the foam solution has been discharged, and it continues until someone manually shuts off the water supply. This manual shutdown gives the operator control to stop flow when the foam work is complete and the hazard is addressed, preventing ongoing water damage and uncontrolled discharge. Automatic stopping or draining isn’t how this sequence is designed to function in NFPA 16.
