What is the primary purpose of a plumbing system?

The primary purpose of a plumbing system is to facilitate waste disposal and water supply. Plumbing systems are designed to transport water to various fixtures and appliances within a building, such as sinks, toilets, and showers, ensuring that clean water is readily available for use. Additionally, these systems are crucial for the safe and efficient disposal of wastewater. This dual function of providing potable water and removing sewage is essential for maintaining hygiene, health, and comfort in residential and commercial settings.

Other options, while they may relate to building services, do not accurately capture the fundamental role of plumbing. Heating systems are typically managed through HVAC separate from plumbing. Building regulations pertain to compliance and standards but do not define the workings of plumbing systems themselves. Connecting buildings to energy sources generally falls under electrical or mechanical systems, not plumbing. Thus, the essence of plumbing lies in its role in water and waste management.
