In a sprinkler system, what is the function of the riser?

The key idea here is how water moves through the sprinkler system via vertical piping to reach every area. The riser acts as the vertical conduit that brings water from the building’s main supply into the sprinkler network and then feeds the branch lines that run to the individual sprinklers on each floor. That makes it the component responsible for distributing water from the main supply into the system’s branch lines so sprinklers can be activated where needed. The other functions described—being the overall main supply, feeding the fire department connection, or venting air—are handled by other parts of the system, not the riser.
