Plumbing is the system of pipes, fixtures, and fittings used to supply water to buildings and remove wastewater. It plays a critical role in maintaining hygiene and sanitation in homes, offices, and public facilities. Plumbers are skilled professionals who install, repair, and maintain these systems, ensuring that clean water flows in and waste flows out safely. Modern plumbing includes various materials such as copper, PVC, and PEX pipes. A well-designed plumbing system prevents leaks, water contamination, and flooding, making it essential for public health and comfort.
