DEA Contributes Changes to National Standard Plumbing Code

The Dispensing Equipment Alliance (DEA), comprised of the leading manufacturers in the dispensing equipment industry, has contributed new language to the 2018 National Standard Plumbing Code (NSPC) to provide a clear method of installing chemical dispensers.

Volunteers from DEA member companies sitting on the DEA Code Committee reviewed the 2015 NSPC and recommended the additional language, citing the importance of protecting Atmospheric Vacuum Breaker backflow devices on faucets. Language was drafted and submitted to the NSPC requiring a new standard, IAPMO PS-104, that requires a pressure bleed device to be installed on the faucet, thus protecting the backflow device.

“Protecting our drinking water is a primary goal, really a core value, of the DEA,” said Jamison Kortas, a member of the DEA’s Executive Steering Committee. “The DEA is providing leadership for the industry to protect our most precious resources, along with providing guidance on how best to install and maintain chemical dispensers.

“The DEA has been attempting to work with all model plumbing code organizations to ensure the language in the codes pertaining to the dispensing industry is up-to-date with the latest technology. The DEA continues to work to develop and utilize standard language that has input from all interested parties and looks at all facets of the installation codes to meets the needs of everyone.”

The National Association of Plumbing-Heating-Cooling Contractors (NAPHCC) NSPC Code Committee met on March 9 to review proposed changes to the 2018 NSPC and voted unanimously to approve the language submitted by the DEA.

“The inclusion of these provisions will serve all people well, including the dispensing equipment industry, the facility owners, the Inspection community and particularly the end user,” Kortas said. “The DEA is very proud of this achievement!”

The DEA has been diligently working with the International Association of Plumbing and Mechanical Officials (IAPMO) and ASSE International to provide the highest level of safety and performance in equipment and installations. The NSPC has been developed and published by NAPHCC since 1933.

In the recent past, the DEA has similarly submitted language to the Uniform Plumbing Code (UPC®), the most widely utilized plumbing code in the world, and to the Massachusetts Board of State Examiners of Plumbers and Gas Fitters.

The Dispensing Equipment Alliance (DEA) is established for the purpose of providing superior leadership and fostering the awareness of chemical dispensing technology and its impact on public health and safety through comprehensive educational activities, products, codes and standards, and public awareness initiatives. In addition, the DEA will serve as a clearinghouse of experience, ideas, and information to further the objectives and sustain interest on behalf of the DEA membership.


IAPMO develops and publishes the Uniform Plumbing Code®, the most widely recognized code of practice used by the plumbing industry worldwide; Uniform Mechanical Code®; Uniform Swimming Pool, Spa and Hot Tub Code®; and Uniform Solar Energy, Hydronics and Geothermal Code — the only plumbing, mechanical, solar energy and swimming pool codes designated by ANSI as American National Standards — and the Water Efficiency Standard (WE-Stand)™. IAPMO works with government, contractors, labor force, and manufacturers to produce product standards, technical manuals, personnel certification/educational programs and additional resources in order to meet the ever-evolving demands of the industry in protecting public health and safety.
