Plumbers perform journeyman level plumbing work on various heating, cooling, water and sewage systems, and other related equipment to assure all systems are working properly. An employee in this classification receives overall objectives and resources available and develops deadlines, projects, and work to be done in consultation with the supervisor. The employee plans and carries out the assignment, resolves most of the conflicts that arise, and coordinates work with others, as necessary; also interprets policy on own initiative in terms of established objectives. Work assignments are received verbally and through work orders. Work is performed independently with latitude for determining materials. Work is subjected to inspection by a supervisor and inspectors from the local jurisdiction during construction and upon completion. Plumbers keep the supervisor informed on the progress of assigned tasks.
