The Plumbing Code is a set of regulations that governs the installation and maintenance of plumbing systems in buildings. It ensures that water supply, drainage, and waste disposal systems are safe, efficient, and environmentally friendly. These codes are designed to protect public health and prevent water contamination. Different regions may have their own versions of the Plumbing Code, often based on national standards. Compliance with these codes is essential for obtaining building permits and passing inspections. By following the Plumbing Code, plumbers and builders help ensure that plumbing systems function properly and meet safety requirements.
