Building Code Committee to draft recommendations that could be used by local governments in preparing codes. The committee worked with the National Bureau of Standards until 1933, when funding was curtailed. In 1921 the Building Code Committee and in 1925 a report was issued titled "Recommended Practice for Arrangement of Building Codes" which consisted of 19 chapter, including Chapter 15 on plumbing. This report was known informally as the "Hoover Code" as it was issued under the signature of the Secretary of Commerce Herbert Hoover. Chapter 15 was itself divided into 14 Sections including topics such as Joints and connections, Water supply and distribution, and House drains and sewers. In 1926, a group of Los Angeles plumbing inspectors recognized that there were no uniform requirements for the installation and maintenance of plumbing systems, and at that point in time disease was rampant, a lot of it spread through improper sanitation. Disorder in the industry was the result of widely divergent plumbing practices and the use of many different, often conflicting, plumbing codes by local jurisdictions. It was these plumbing inspectors that understood the necessity of developing a model code that could be uniformly applied across jurisdictions. In 1928, the city adopted the first incarnation of a uniform plumbing code developed by the Los Angeles City Plumbing Inspectors Association (LACPIA) and based on the input from a committee of plumbing inspectors, master and journeyman plumbers, and sanitary and mechanical engineers, assisted by public utility companies and the plumbing industry. The product of this effort, the first edition of the Uniform Plumbing Code (UPC) was officially adopted by the Western Plumbing Officials Association in 1945, which later changed its name to IAPMO in 1966 when the scope of the association’s work increased. The code has been widely used over the past five decades by jurisdictions throughout the United States and internationally. With the publication of the 2003 Edition of the Uniform Plumbing Code, another significant milestone was reached. For the first time in the history of the United States, a plumbing code was developed through a true consensus process. The 2012 edition represents the most current approaches in the plumbing field and is the fourth edition developed under the ANSI consensus process. Contributions to the content of the code were made by every segment of the built industry, including such diverse interests as consumers, enforcing authorities, installers/maintainers, insurance, labor, manufacturers, research/standards/testing laboratories,
