Plumbing systems are essential networks that transport water and waste in buildings. They consist of pipes, fixtures, and fittings that work together to provide clean water for drinking, cooking, and bathing, while also removing wastewater safely. These systems include both supply lines, which bring fresh water into a home, and drainage systems, which carry away used water and sewage. Proper installation and maintenance of plumbing systems are crucial to prevent leaks, clogs, and other issues that can lead to costly repairs and health hazards.
