What does the acronym CWL stand for in plumbing?

The acronym CWL stands for Cold Water Line, which is an important component in plumbing systems. The Cold Water Line is responsible for supplying cold water to various fixtures and appliances, such as sinks, toilets, and refrigerators. Understanding this term is vital for anyone involved in plumbing, as it relates to the design and functionality of water distribution in residential and commercial buildings.

This knowledge is particularly useful during installation, repairs, or maintenance of plumbing systems, ensuring that cold water is properly routed and accessible where necessary. The other options, while related to water systems, refer to different types of lines that serve various purposes, but do not specifically describe the standard plumbing terminology represented by CWL.
