Which standard regulates the installation of plumbing fixtures in Arizona?

The Arizona Administrative Code, Title 18, Chapter 5 specifically governs plumbing within Arizona, establishing the standards, requirements, and guidelines that must be adhered to for the installation of plumbing fixtures. This code is tailored to address the specific needs and conditions within Arizona, taking into account local regulations, climate considerations, and public health and safety requirements. It also incorporates amendments that may be necessary for compliance with state laws.

While other codes, such as the National Plumbing Code and the Uniform Plumbing Code, provide valuable frameworks for plumbing installation practices, they are not the governing documents for plumbing in Arizona. Instead, they offer guidelines that can be accepted or adapted within state-specific regulations. Therefore, the Arizona Administrative Code, Title 18, Chapter 5 is the authoritative source that plumbers and contractors in Arizona must follow to ensure compliance with local standards and maintain safety and efficiency in plumbing installations.
