Which component is typically located between the water source and the sprinkler system to control flow?

• A. Between Water Source and Sprinkler System
• B. Between Risers and Branches
• C. Between Cross Mains and Riser
• D. Between Fire Department Connection and Riser

Answer: (A)

The main idea is that there is a control device placed at the entry point where the water source feeds the sprinkler system. This component, a valve, is used to regulate and isolate the flow into the system. Placing it between the water source and the sprinkler system lets you turn the water on or off and adjust the flow for testing, maintenance, or emergencies without altering the internal piping downstream. Other locations mentioned are parts of how water moves within the system or how the system is connected to an external supply, but they aren’t the primary control point for the incoming supply.
