The 2016 edition of the California Plumbing Code (CPC©) represents the most current approaches in the plumbing field. This code is embedded with the 2015 Edition of the Uniform Plumbing Code (UPC©) with the California amendments. It is the fifth edition developed under the American National Standards Institute (ANSI) process. Contributions to the content of this code were made by every segment of the built industry, including such diverse interests as consumers, enforcing authorities, installers/maintainers, labor, manufacturers, research/standards/ testing laboratories, special experts, and users. The CPC is designed to provide consumers with safe and sanitary plumbing systems while, at the same time, allowing latitude for innovation and new technologies. Key changes to the 2016 CPC include: New product standards and flow rates for plumbing fixtures and fixture fittings. (Chapter 4). Lead-content provisions have been revised to address the minimum acceptable percentage lead content for pipes and fittings (Chapter 6). New provisions for residential fire sprinkler systems (Chapter 6). New requirements for the insulation of hot water piping (Chapter 6). New requirements for medical gas and vacuum systems based on NFPA 99. New testing and inspection provisions for nonpotable alternate water source systems (Chapter 15). New requirements for testing, inspection, and maintenance of nonpotable rainwater catchment systems (Chapter 16).
