When the sprinkler head is triggered, a valve to the pipe system is opened, releasing the water that is kept under pressure from the pipes. The water is quickly pushed out of the pipes through the sprinkler head, spraying water downward and out to the sides.
One such valve each fire sprinkler system is. required to have is a main drain valve assembly (A). The main drain valve assembly is normally located at the system riser. Its purpose is twofold. First, it is used as a central point to drain water from the entire system. As such, where practicable, all. system piping should be arranged to drain to the main drain valve. Its second purpose is to serve. as a tool to measure incoming water flow.
