A waste pipe is defined as which of the following?

• A. Any pipe that carries discharge from fixtures
• B. A pipe that carries rainwater
• C. A pipe that vents air
• D. A pipe that carries discharge from toilets only

Answer: (A)

A waste pipe is the conduit that carries used water from fixtures to the building drain or sewer. It handles discharge from all fixtures—sinks, showers, bathtubs, dishwashers, and toilets—so describing it as any pipe that carries discharge from fixtures captures that broad role. The other descriptions point to systems that aren’t waste pipes: rainwater pipes handle storm runoff, vent pipes carry air to equalize pressure rather than drain liquid, and a pipe that carries discharge from toilets only is too limited and doesn’t include other fixture Waste.
