Which section of plumbing focuses on water supply systems?

The section of plumbing that focuses specifically on water supply systems is the water service. This area encompasses the design, installation, and maintenance of the systems responsible for delivering clean, potable water to buildings and other structures. It involves understanding the source of water, the distribution network, and the necessary components such as piping, fittings, valves, and fixtures that facilitate the flow of water within properties.

While drainage systems, waste systems, and vent systems are crucial aspects of plumbing, they primarily deal with the removal and management of wastewater and air circulation within plumbing systems, rather than the delivery of fresh water. Understanding water service is essential for ensuring that buildings have a reliable and safe water supply, which is fundamental for health and sanitation.
