Whether you are about to graduate from high school or have realized college or your current job is not the right choice, you should strongly consider working in the piping industry. Our apprenticeship training programs are unrivaled, and you work while you learn, making it the optimum educational foundation for long-term success.

If you are currently working in the industry for a non-union contractor, discover the many benefits of becoming a member of the United Association. By joining an MSPTA-affiliated union, those with experience in the piping industry will earn top wages, excellent full-family health insurance, and great retirement benefits to depend on.

We partner with reputable contractors who perform work in a fair and just manner. When it comes to contractors who don’t—who violate the law and extort workers—we hold them accountable.
