To understand how pipes run between equipment and fixtures, refer to which drawing?

• A. Mechanical Drawing
• B. Electrical Drawing
• C. Plumbing Drawing
• D. Architectural Drawing

Answer: (C)

Piping between equipment and fixtures is shown on the plumbing drawing. This drawing specifically maps the water supply and drainage network, detailing how pipes run from equipment (like a water heater, boiler, or pump) to fixtures (such as sinks, toilets, and showers). It includes pipe routes, sizes, materials, fittings, slopes, venting, and cleanouts, providing the practical guide needed for installation and inspection.

Mechanical drawings cover HVAC and other mechanical systems, electrical drawings show wiring and devices, and architectural drawings focus on layout and spaces rather than the plumbing routes.
