The United Association of Journeymen and Apprentices of the Plumbing and Pipe Fitting Industry of the United States, Canada (UA), affiliated with the national building trades, represents approximately 340,000 plumbers, pipefitters, sprinkler fitters, service technicians and welders in local unions across North America. We also honor a federation agreement with both the Australian Plumbing Trades Employees Union (PTEU) and Irish Technical, Engineering Electrical Union (TEEU).

The UA has been training qualified pipe tradesmen and women longer than anyone else in the industry. We provide the premier training programs available in the industry today, including five-year apprenticeship programs, extensive journeyman training, a comprehensive, five-year instructor training program, and numerous certification programs. We help our signatory contractors grow their market share by identifying new opportunities, providing support and connecting them to the safest, most skilled and most highly trained workforce in the industry.
