What encompasses the plumbing system?

The plumbing system encompasses various components that are essential for maintaining the flow and management of water within a building. The correct choice highlights both the water supply and waste management components, which are fundamental to any plumbing system.

The water supply system includes pipes, valves, and fixtures that bring fresh water into a building. This system is crucial for providing potable water for various uses such as drinking, cooking, and bathing. On the other hand, the waste management component is responsible for the safe and sanitary disposal of wastewater and sewage. This includes drainage pipes, traps, and sewer connections that work together to transport waste away from the building efficiently.

It's important to have a comprehensive understanding that plumbing is not limited to only the visible components, such as fixtures or drainage pipes, but includes the interconnected systems that ensure both the delivery of clean water and the effective removal of waste. Heating and ventilation systems, while they may share space with plumbing, are distinct systems and not considered part of the plumbing infrastructure.
