Which code regulates the installation of piping systems?

The Uniform Plumbing Code specifically regulates the installation of piping systems, covering various aspects such as design, materials, and safety standards for plumbing installations. This code is widely adopted and provides guidelines to ensure that plumbing work is performed safely and efficiently, helping to protect public health and welfare. It establishes standards for different types of plumbing systems, including sanitary drainage, venting, and piping for water distribution.

The other codes mentioned, while important in their respective areas, do not focus primarily on the installation of piping systems. The National Electric Code addresses electrical systems to ensure safe electrical installations, the American National Standards Code encompasses a broad range of standards across various industries, and the International Building Code provides regulations for building construction but does not specifically address plumbing piping systems in detail.
