The Uniform Plumbing Code is published by the International Association of Plumbing and Mechanical Officials. The latest edition, the 2003 Uniform Plumbing Code, is also known as IAPMO/ANSI UPC 1-2003. This new edition was developed through an ANSI-accredited consensus process, and contributions to the content of the code were made by consumers, enforcing authorities, installers/maintainers, insurance, labor, manufacturers, research/standards/testing laboratories, special experts, and users. The first edition of the Uniform Plumbing Code was officially adopted by IAPMO in 1945.
