About Us

History + -

The history of the Plumbers Union in Pittsburgh dates back to the late 1870’s, when it was affiliated with the Knights of Labor and later with the American Federation of Labor. By the fall of 1889, it was definitely decided to apply to the United Association for a charter, which was granted on May 17, 1890.

The original membership consisted of approximately 90 craftsmen.

Experience + -

Our contractors employ Local 27 members in many different construction applications. We work in the heavy industrial, commercial and residential sectors of the construction industry. Our workforce takes pride in partnering with our signatory contractors in providing sophisticated piping systems to end user. From underground installation to final connections of fixtures and equipment, a plumber is required to have all the physical and mental skills needed to get the job done right the first time.

Training + -

No other organization serves the training needs of the piping industry like the United Association. For over a century, the UA has been training the most highly-qualified workers in the United States and Canada.

Over the past several decades, the United Association’s training programs have produced a stable, skilled workforce responsible for building and maintaining piping systems in the various industrial and residential facilities that make up the North American landscape.

  • Local 27’s apprenticeship program provided me with the essential skills needed to be successful in the pipe trades. On top of their five year training program, you are provided with continuing education throughout your career to stay at the forefront of the industry, as well as opportunities in welding to further your skill set. I highly recommend anyone who is on the fence, to go for it. Local 27 changed my life for the better, and continues to provide a platform from which I can successfully provide for my family.
