What is the role of a supply line?

To provide drainage from the sink
To transport water from the water main to the house
To regulate water temperature
To filter impurities from the water supply

The correct answer is: To transport water from the water main to the house

The role of a supply line is to transport water from the water main to the house. This is an essential function because the supply line is the conduit through which clean water enters a building, ensuring that faucets, showers, and appliances have access to water for various uses, including drinking, cooking, and sanitation. Understanding this role is crucial for professionals involved in construction, plumbing, and inspections, as any issues with supply lines can greatly affect the water quality and availability in a property. This function is distinct from other processes such as drainage, which pertains to the removal of wastewater, or temperature regulation, which is relevant to systems like water heaters. Filtering impurities is also a separate process related to water quality management, usually handled at specific points in the plumbing system or via treatment facilities rather than by the supply line itself.
