Plumbers and Steamfitters Local 486 was established in 1995 by the consolidation of Plumbers Local 48 and Steamfitters Local 438. We represent nearly 2,000 union-trained plumbers and steamfitters, and are affiliated with the United Association of Journeymen and Apprentices of the Plumbing and Pipefitting Industry of the United States and Canada.

Our members are highly trained craftsmen who fabricate, install and service piping systems. They may be found on jobsites involving single-family homes, garden and high-rise apartment buildings, large and small office buildings, power plants, chemical installations, factories, public buildings and health care facilities.

Local 486 represents its members by providing job information, training programs and quality fringe benefits.

We are also an important resource for contractors and owners. We promote good labor relations. We can provide an ample supply of highly trained labor, matching any size project need or skill requirement, including welding and specialty crafts such as hazardous materials handling and medical gas piping.

Our mission is to ensure that every HVACR technician, plumber and steamfitter in the State of Maryland receives a respectable wage and retirement option by educating all community leaders, legislators, and unrepresented workers on the importance of a career, with exceptional pay and benefits, and the right to retire with dignity.
