A water distribution pipe that routes the water supply vertically one full story or more is called a ?

• A. Riser
• B. Branch
• C. Line
• D. Main

Answer: (A)

A vertical pipe that runs through one or more full stories to deliver water to the floors above is called a riser. It serves as the main vertical distribution path, carrying water from the building’s primary supply to floor-level distribution, from which branch lines feed individual fixtures on each floor. The main is the primary feed line into the system, and branches are the pipes that leave the vertical path to supply fixtures. So the vertical, multi-story distribution pipe is the riser.
