The plumber performs duties at the Journeyman Plumber level in the Maintenance and Operations Section of Engineering Service. The plumber will be able to perform the work of a Journeyman plumber independently with little to no supervision. The journeyman will be knowledgeable in these systems able to troubleshoot, diagnose, plan the job, create a materials list and execute the work independently as well as working as part of a team. This entails knowledge of plumbing, steam fitting, and mechanical skills. The plumber works on a variety of systems such as steam distribution, water supply, fire sprinklers, drainage, sewage, oxygen, medical air, vacuum and nitrous oxide distribution and storage as well as mechanical equipment and appliances.
Repairs Plumbing Systems: The work involves installing, modifying, and repairing new and existing utility, supply, and disposal systems. Repairs equipment such as sewage, water, oil, and gas distribution systems and water closets, tubs, fire sprinkler systems, and showers. Works from building plans, blueprints, and sketches, to plan and lay out the routing, placement, slant, slope, fall, and proper operation, of systems and equipment. Uses tools and equipment such as plumb bobs, mercury gauges, dividers, closet augers, sewer snakes, high pressure jitters and hydrostatic pumps.
Installs Plumbing Systems: Plumber must possess demonstrable knowledge of the plumbing code.
Install plumbing systems. Installs, modifies, and repairs systems by locating and tapping main lines, setting up system routes, placing and cutting route openings, placing hangers for proper level and slope. Determines and installs valves, traps, and unions needed for proper operation systems. Installs equipment by completing the routing and placement of systems leading to the equipment, and seating, hooking up, and testing the equipment.
Modifies Plumbing Systems: Plans and lays out the needed routing, placement, slant, slope and fall of systems. The plumber tests and makes needed adjustments to systems and equipment for proper operation, flow, drainage, and sanitary conditions.
Installs, Modifies, Repairs High Pressure Piping Systems: Installs, modifies, repairs, and maintains high temperature water and high-pressure piping systems such as hydraulic, nitrogen, oxygen, steam-heating, and steam- generating systems. Installs and repairs such items as steam generators, vacuum, air, water, and condensate pumps, radiators, automatic and manual valves and flash and expansion tanks. Piping systems include water, natural gas, high/medium/low pressure steam and condensate, medical gases, compressed air, heating and cooling, sewer, fire protection, irrigation, and deionized water. Sets up system routes, places and cuts route openings, installs regulating devices, and places hangers for proper pitch and elevation.
Determines and installs risers, flexible branches, expansion joints, pumps, gauges, and pressure regulators in the combination needed to support the pressures of the systems and that ensure the proper operation of the systems. Reads and interprets blueprints, layout sketches, manufacturers' literature and specifications for sizing, estimating, installing, and repairing new or existing piping systems. Replaces sections of pipe, repairs steam traps and relief and control valves. Cuts, threads, and connects pipes by means of union, flanges, and sweating. Fits pipe sections by screwing, bolting, brazing, welding, gluing, fusing, and soldering. Tests systems and equipment for proper operation, circulation, flow, pressure, and leak-free joints. Traces and troubleshoots pipe lines, systems, and equipment to locate and repair leaks and trouble spots. Performs safety and preventive maintenance inspections of systems and equipment.
Performs other related duties as assigned.
Skill and Knowledge
Plumber must possess demonstrable knowledge of how various high-pressure piping systems and equipment, such as steam heating, steam generation, and circulating pumps, are installed and operate. Ability to plan and lay out the installation, modification, and repair of various new and existing piping systems and equipment. Ability to interpret and apply building plans and blueprints, and to use shop mathematics to lay out angles, arcs, and circles. Skill in any of the accepted trade methods and techniques. Skill in the use of tools and equipment such as sliding squares, plumb bobs, core drills, grinders, pipe cutters, pipe threaders and pipe wrenches. The plumber possesses a good working knowledge and understanding of the Uniform Plumbing and Mechanical Code and able to apply this knowledge of plumbing principles.
Work will be assigned orally and through work orders, building plans, and blueprints. The pipe fitter plans and lays out the needed routing, placement, pitch, incline, and elevation of systems and equipment. Figures pressures in the systems and sees that the piping, valves, fittings, and equipment are proper for the work. Completes installations, modifications, and repairs with little or no check during their progress or upon completion. Tests systems and equipment after completing work for proper circulation, flow, pressure, and leak- free joints. The VA COR checks the overall work to see that it meets accepted trade standards.
Makes repairs and installations from ladders, scaffolding, and platforms, and where the systems and equipment worked on are in hard-to-reach places. Stands, stoops, bends, kneels, climbs and works in tiring and uncomfortable positions. Frequently handles, lifts, carries, and sets up parts and equipment that weigh up to 23 kilograms (50 pounds). Occasionally, lifts and carry items that weigh over 23 kilograms (50 pounds).
