Detailed Guide for Plumbers, Pipefitters, and Steamfitters in San Diego County
May also be called: Gas Line Installers; Hot Water Heater Installers; and Sprinkling System Installers
What Would I Do?
Plumbers, Pipefitters, and Steamfitters* assemble, install, and repair pipe systems according to plans and plumbing codes. They work with piping systems that move liquid, gas, or semisolid material. Plumbers, Pipefitters, and Steamfitters also install plumbing for rainwater capture, gray water, or solar panel systems.
Plumbers install sinks, bathtubs, toilets, and other fixtures and connect them to water and sewage systems. They maintain existing plumbing systems by checking for breaks and leaks, and making any necessary repairs. Some repairs may consist of digging down into the soil or removing concrete. Plumbers may also replace existing plumbing fixtures and fittings with energy-efficient equipment, such as faucet flow restrictors or low-flow faucets and toilets. Some journey-level Plumbers may give written estimates for the cost of their work.
Plumbers also follow blueprints so plumbing lines go in the right place. They plan the job by determining the size and type of pipe to be used and lay out the exact route the piping will take. Plumbers may have to cut holes in walls, ceilings, and floors of a building. Others may hang steel supports from ceiling joists to hold the pipe in place. To assemble a system, pipe is cut to correct lengths and connected together with fittings. After the pipe is in place, Plumbers install the fixtures and appliances and then connect the system to the outside water or sewer lines. Finally, using pressure gauges, they check the system to ensure that the plumbing works properly. Pipes and connections can be made from a variety of lead-free or low-lead materials, such as copper, plastic, ceramic, cast iron, or steel.
In new construction work, Plumbers must follow the California Green Building Standards Code (CALGreen). They may perform calculations to meet requirements for water efficiency, conservation, and reduction. Plumbers must select the proper plumbing fixtures. Some fixtures include water saving faucets, showerheads, and toilets, and tankless hot water heaters. They may also install programmable irrigation controllers that are sensitive to the weather and moisture content of the soil.
Pipefitters and Steamfitters install, maintain, and repair both high- and low-pressure pipe systems that carry water, steam, air, or other liquids or gases. They may also install heating and cooling equipment, and regulating-control systems to reduce water or energy consumption. They also install pipe systems to support alternative energy-fueled systems, such as for geothermal or ethanol power plants.
An emerging occupation related to Plumbers is Solar Thermal Installers and Technicians. To read more about this kind of work, go to the Green Occupational Guides on the California Labor Market Information Web site and select Solar Thermal Installers and Technicians.
Tools and Technology
Plumbers, Pipefitters, and Steamfitters use a variety of tools and technology in the course of their work, including blow torches, hoists, laptop computers, levels, pipe cutters, pipe-threading machines, saws, screwdrivers, smart phones, welders, wrenches, and software, such as computer-aided design (CAD/CADD), project management, spreadsheet, and word processing.
Plumbers, Pipefitters, and Steamfitters will play a crucial role in the green economy through retrofitting and the construction of new green buildings. They will install water-saving appliances and plumbing products to help with conservation efforts.
