What type of drawing illustrates the route for both potable water and sanitary water?

Plumbing drawings are specifically designed to illustrate the layout and routing of both potable (drinking) water lines and sanitary waste lines. These detailed depictions provide information on the sizes, types, and measurements of pipes, as well as the locations of fixtures like sinks, toilets, and valves. By clearly showing how these systems interact within a building's infrastructure, plumbing drawings ensure that installation and maintenance can proceed efficiently while adhering to relevant codes and regulations.

In contrast, architectural drawings primarily focus on the overall design and structure of the building, including walls, windows, and door placements, but do not specifically illustrate plumbing details. Electrical drawings concentrate on the wiring and lighting layout, while mechanical drawings pertain to HVAC systems and other mechanical components rather than plumbing systems. Thus, plumbing drawings are the essential resource for understanding the routing of both potable and sanitary water systems.
