Which component carries water to fire protection fixtures above ground?

• A. Riser
• B. Sprinkler
• C. Flow Hydrant
• D. PIV

Answer: (A)

Water is delivered to fire protection fixtures on various floors through a vertical distribution pipe called a riser. This upward-running pipe carries water from the building’s main supply to sprinklers and other outlets on each level, ensuring access above ground. The device that actually releases water at a sprinkler head is the sprinkler itself, not the conduit. A flow hydrant is an external firefighter’s hydrant used to obtain water from the system outside the building, not to feed internal fixtures. A post indicator valve (PIV) is an isolation valve used to shut off water to a section of the system, not to carry water to the fixtures.
