The Uniform Plumbing Code (UPC) is a set of regulations that provides standards for plumbing systems in buildings. It aims to ensure safe and efficient plumbing practices, protecting public health and the environment. The UPC covers various aspects, including installation, maintenance, and inspection of plumbing systems. Developed by the International Association of Plumbing and Mechanical Officials (IAPMO), the UPC is widely adopted across many regions. It serves as a guideline for plumbers, contractors, and building officials, helping to create uniformity in plumbing practices and ensuring compliance with local laws and regulations.
