Which drawing would you use to plan the locations of water supply and restroom fixtures?

• A. Floor plans
• B. Plumbing plan
• C. Reflected ceiling plan
• D. Foundation plan

Answer: (B)

This item tests understanding of which drawing communicates where plumbing components and fixtures belong. A plumbing plan is specifically created to lay out the water supply lines, drainage, venting, and all fixtures like sinks, toilets, urinals, and showers, showing how they connect to mains and stacks. It coordinates the locations and sizes of pipes with the fixture locations, which is essential for installation and code compliance. A floor plan shows walls, doors, and general room layouts, and may place fixtures, but it doesn’t detail piping routes or how the system is actually plumbed. A reflected ceiling plan depicts ceiling elements like lights and ventilation, not plumbing. A foundation plan focuses on structural footing and below-ground details, not plumbing. So the best drawing for planning water supply and restroom fixtures is the plumbing plan.
