2015 Uniform Plumbing Code (UPC®) eBook Now Available

The International Association of Plumbing and Mechanical Officials (IAPMO®) has released the electronic version of its 2015 edition of the Uniform Plumbing Code (UPC®). The digital version, viewable on computers, tablets and smart phones, can be purchased and downloaded via the IAPMO web store.

In December, the IAPMO Standards Council issued the 2015 edition of the UPC, designated as an American National Standard for the fifth time.

IAPMO’s ANSI-accredited process brings together volunteers representing a variety of viewpoints and interests to achieve consensus on plumbing practices. The UPC is the only plumbing code of practice to be designated an American National Standard.

Significant changes to the UPC include:
• New product standards for plumbing fixtures such as lavatories, showers, bathtubs and whirlpool bathtubs, bidets, urinals, drinking fountains, and sinks (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 (Chapter 13)
• 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)

Introduced in Los Angeles in 1928 and formally published as the Uniform Plumbing Code in 1945, the UPC is developed to govern the installation and inspection of plumbing systems as a means of promoting the public’s health, safety and welfare. Developed and subsequently republished at the conclusion of each three-year code cycle, the UPC is designed to provide consumers with safe plumbing systems while, at the same time, allowing latitude for innovation and new technologies.

The public at large is encouraged and invited to participate in IAPMO’s open consensus code development process. A code development timeline and other relevant information are available at IAPMO’s website.
