Plumbers install, maintain, and repair water supply lines, drainage systems, gas lines, and related fixtures in residential, commercial, and industrial buildings. The work involves reading blueprints and building codes, measuring and cutting pipes, assembling and installing pipes and fittings, testing systems for leaks using pressure gauges, and troubleshooting problems that range from simple clogs to complex system failures. Plumbers work in diverse environments—from new construction sites to century-old buildings with outdated systems—requiring them to adapt their approach to each unique situation. The job demands physical stamina for working in cramped spaces, excellent problem-solving abilities for diagnosing issues that aren't immediately visible, and strong customer service skills for explaining technical problems to homeowners. Many plumbers specialize in areas like gas fitting, medical gas systems, fire sprinklers, or green plumbing technologies.

Electricians install, maintain, and repair electrical power, communications, lighting, and control systems in homes, businesses, factories, and other structures. The work encompasses reading technical diagrams and blueprints, installing wiring and electrical components, using testing devices like ohmmeters and voltmeters to check connections, inspecting electrical systems for compliance with codes, and diagnosing malfunctions. Electricians must stay current with evolving electrical codes, which vary by jurisdiction and are updated regularly for safety. The role spans diverse specializations—residential wirers focus on homes, commercial electricians handle office buildings and retail spaces, industrial electricians work with heavy machinery, and lineworkers maintain the power grid. The explosion of smart home technology, EV charging infrastructure, and solar integration has created new specialties requiring electricians to continually update their skills. Work conditions vary from new construction to renovating systems in buildings that may be decades old.

Pipefitters install and maintain piping systems that carry chemicals, acids, gases, and other materials in industrial and manufacturing settings, often involving high-pressure and high-temperature systems. The work requires reading blueprints, cutting and threading pipe, fitting and welding components, testing systems for leaks, and ensuring compliance with safety codes. Pipefitters work in power plants, refineries, chemical facilities, pharmaceutical manufacturing, shipyards, and commercial buildings. Systems include steam, compressed air, hydraulics, process piping, and fire suppression. The work demands precision—systems carry hazardous materials or operate under extreme conditions where failures have serious consequences. Specialized knowledge includes different pipe materials, fitting methods, and code requirements for various applications. Physical demands include working in industrial environments, confined spaces, and elevated positions.
