Classification Standard


A Maintenance Assistant (Plumber and Steamfitter) performs semiskilled activities in the installation, alteration and repair of pipes, fittings and fixtures of heating, ventilating, heating control, and water and drainage systems, generally under the supervision of a Plumber and Steamfitter.

Positions in this class exist in several agencies with the greatest number in the Department of Mental Hygiene and State University.


Maintenance Assistant (Plumber and Steamfitter), as a semiskilled employee, performs the routine installation and repair tasks in the plumbing and steamfitting trades. In learning and perfecting their craft skills incumbents may perform journey-level activities under supervision or after receiving detailed instructions. Maintenance Assistants (Plumber and Steamfitter) may supervise maintenance helpers, laborers and other relatively unskilled workers in performing manual tasks involving elementary skills.

There are a number of other specialized Maintenance Assistant classes having parenthetic designations describing the predominant trade areas to which the incumbent is assigned; i.e., carpenter, mason and plasterer, painter, and electrician. Although incumbents of such classes may perform tasks normally associated with more than one trade, most of their time is spent performing tasks typical of the trade indicated by the special title.

Incumbents of Maintenance Assistant positions without a parenthetic designating a trade specialty are usually found in relatively small maintenance staffs where such specialization is not desirable or in maintenance pools where specialization is not efficient. However, incumbents may be assigned to tasks such as those described for any of the specialized positions of Maintenance Assistant.

Maintenance Assistant is distinguished from Maintenance Helper by the latterÂ’s performance of relatively unskilled tasks in direct support of semiskilled and/or skilled trades positions. Such tasks involve a limited use of the tools and equipment of the trade under very specific instructions and supervision of either a Maintenance Assistant or a journey-level position.

The position of Plumber and Steamfitter is distinguished from Maintenance Assistant (Plumber and Steamfitter) by the performance of skilled work and by responsibility for all plumbing and steamfitting work in an assigned area, on an assigned project, or for an entire facility including the planning and laying out of work, estimating quantity and types of materials, and determining the cause of trouble in plumbing and heating systems and equipment. Positions of Plumber and Steamfitter frequently supervise others in performing plumbing and steamfitting work.

As assigned, a Maintenance Assistant (Plumber and Steamfitter) functions as a lead worker over a small maintenance crew usually consisting of maintenance helpers and laborers.


Under direction, incumbents may participate in work in other maintenance specialties.


The nature of Maintenance Assistant (Plumber and Steamfitter) activities generally restricts relationships to employees working within the same organizational unit. As assigned, incumbents supervise a small maintenance crew characterized by frequent oral communications in assigning work and providing instructions. Written and oral communications with the general public are not typical of this class.


Maintenance Assistants (Plumber and Steamfitter) are supervised by skilled craft positions usually a Plumber and Steamfitter or a General Mechanic. Work priorities and the nature and extent of work to be performed are prescribed and materials are furnished. When necessary, the work to be performed is laid out by the supervisor who gives specific instructions, assists in performing the more difficult tasks and inspects the job while in progress and when completed to insure that instructions have been followed and that the quality of the work is satisfactory. However, a Maintenance Assistant (Plumber and Steamfitter) may perform the activities of this class with considerable independence when supervision is not immediately available due to the geographic location of the assignment. In addition, incumbents are expected to perform the more routine and repetitive tasks with considerable independence.

As assigned, a Maintenance Assistant (Plumber and Steamfitter) supervises a maintenance crew consisting of maintenance helpers, laborers and other relatively unskilled workers by making assignments, giving instructions and providing assistance in performing the work.


Maintenance Assistants (Plumber and Steamfitter) use the tools of the plumbing and steamfitting trade, including the standard hand tools, portable power tools and shop equipment. They may occasionally operate a motor vehicle.


As assigned:


Two years of experience in plumbing and/or steamfitting work under the supervision of a skilled tradesperson, or completion of an appropriate two-year technical school course in the plumbing and/or steamfitting trade.
