What is the consequence of a blocked sprinkler head in a system with only one head serving an area?

• A. Water would not reach the area during a fire, compromising protection.
• B. Water would still reach the area due to other paths.
• C. The system automatically compensates with extra water elsewhere.
• D. Blockage has no effect.

Answer: (A)

When a sprinkler system is protecting an area with a single head, that head is the only path for water to reach that space. If that head becomes blocked, water cannot discharge into the area even though the rest of the system may be pressurized. There’s no alternative route to supply that zone, and the system won’t automatically redirect or increase flow elsewhere to compensate. So the area would not receive water during a fire, compromising protection.
