Plumbing industry representatives joined together in March 2025 at state capitols across the United States for a series of Plumbing Industry Days, advocating for policies to improve public health, water quality and economic sustainability.

The events, held in New Jersey, Missouri, Iowa and Massachusetts, were part of the broader March4Water initiative organized by IAPMO and included legislative proclamations in New Jersey and California declaring March as March4Water Month in both states. 

On March 24, plumbing professionals convened at the New Jersey State House in Trenton for the state’s second annual Plumbing Industry Day. Industry representatives met with legislators to discuss support for the National Standard Plumbing Code, water conservation efforts, and regulations for backflow prevention and Legionella control.

On March 25, Missouri hosted its first Pipe Trades Industry Day in Jefferson City, where plumbing professionals gathered to engage with lawmakers and highlight the role of plumbers in safeguarding public health and water quality. The event showcased training trailers from the United Association, providing hands-on demonstrations of the expertise required in plumbing. The event also emphasized policy support for the plumbing industry in addressing challenges such as aging infrastructure, water conservation and lead abatement.

On March 27, Iowa hosted its inaugural Plumbing Industry Day in Des Moines. This event brought together plumbing professionals to discuss the 2024 Uniform Plumbing Code, backflow prevention and water conservation. The day served to highlight the economic impact of the plumbing industry in Iowa, which exceeds $426 million, and emphasized a need for policies to support sustainable water management in the state.

Also on March 27, nearly 200 plumbing industry leaders gathered at the Massachusetts State House in Boston for the third annual Plumbing Industry Day. Among those in attendance were Gov. Maura Healey and other policymakers. Attendees focused on advocating for the Massachusetts Plumbing Code, increased funding for the Division of Occupational Licensure and legislation related to safe drinking water in schools. The event was held in conjunction with World Plumbing Day and World Water Day.

“Safe and reliable water systems don’t happen by chance — they require skilled plumbing professionals governed by effective codes and standards,” said IAPMO CEO Dave Viola. “These events provide a critical platform for showcasing the vital work the plumbing industry does to ensure a safer, more sustainable future for all.”
