What is the best way to increase the flow from a sprinkler head?

The best way to increase the flow from a sprinkler head is to increase the orifice size. The orifice is the opening through which water flows from the sprinkler system. A larger orifice allows more water to be discharged from the sprinkler head, thereby increasing the flow rate. This is particularly important in fire protection because a higher flow rate can help control and extinguish fires more effectively.

When considering other methods, while increasing water pressure can improve flow to some degree, it is ultimately limited by the orifice size. Simply changing the deflector angle may alter the spray pattern but does not directly increase the flow rate. Reducing the orifice size would have the opposite effect, restricting water flow and potentially diminishing the sprinkler's effectiveness. Thus, increasing the orifice size directly correlates with improved water flow, making it the most effective method in this context.
