Plumbers Union Local 75 has been a cornerstone of the plumbing industry in Wisconsin since 1891. Our union was established through the dedication of early members who fought for fair wages and safe working conditions, laying the foundation for our current reputation of credibility and strength. We prioritize the health and safety of the public by ensuring our members adhere to the highest standards of professionalism and technical expertise. Our rigorous apprenticeship program, comparable to a four-year college degree, produces skilled plumbers who are backed by a 5-year residential warranty. We value our members, contractors, and customers, fostering partnerships that drive innovation and excellence in the plumbing trade.

Our continuing education programs ensure that members stay current with evolving technologies, building codes, and safety protocols. We provide skilled labor to contractors while managing benefits like pension and health insurance through collaborative negotiations. Our commitment to safety is demonstrated through mandatory OSHA 30 training and a drug-free workforce initiative. As a union with approximately 1,600 members, we continue to protect workers' rights while advancing the plumbing industry's future. Our historic contributions include landmark projects like the Fiserv Forum and critical infrastructure during the COVID-19 pandemic.
