Whether you’re exploring an apprenticeship or changing careers, this detailed comparison will help you choose the path that fits your interests and earning goals.

Understanding the Roles

What does a plumber do?

Plumbers install, maintain, and repair water‑based piping systems such as potable water lines, waste disposal pipes, gas lines, and appliances like sinks, toilets, and dishwashers. According to Indeed’s career guide, typical tasks include:

• Troubleshooting leaks and clogs in residential or commercial buildings
• Preparing cost estimates and reading blueprints to ensure code compliance
• Installing fixtures and appliances during construction projects
• Repairing or replacing damaged pipes, valves, and fittings
• Maintaining septic systems and cleaning drains

Because much of their work is customer‑facing, plumbers benefit from strong communication and customer‑service skills. They usually work on low‑pressure systems and frequently handle copper, PVC or galvanized metal pipes.

What does a pipefitter do?

Pipefitters, sometimes called fitters, design, assemble and maintain piping systems that carry high‑pressure liquids or gases such as chemicals, steam or fuel. Their work is more specialized than plumbing: pipefitters often weld, cut and shape large metal pipes and fabricate complex systems used in industrial settings. Common responsibilities include:

• Installing, welding and threading heavy‑duty pipes made from stainless steel, nickel or high‑carbon steel
• Maintaining fuel, heating and cooling systems in factories or power plants
• Inspecting piping systems for damage and testing lines with pressure gauges or hydrostatic tests
• Ensuring compliance with industrial safety regulations

Because they work with heavier materials, pipefitters must master welding and fabrication techniques and possess strong math and physics skills. They typically work in industrial environments—factories, refineries, shipyards or energy plants—where high‑pressure systems are common.

Pipefitters vs steamfitters vs sprinkler fitters

The piping trades encompass several specialties. Steamfitters are pipefitters who focus on systems designed to carry high‑pressure steam or liquids, as explained by SkillPointe. They often work in power plants or large commercial HVAC systems. Sprinkler fitters install fire‑suppression systems, while gasfitters specialize in natural‑gas piping. Although each speciality requires similar core skills—blueprint reading, welding and safety awareness—the materials and pressures differ. Understanding these nuances can help you choose a niche that aligns with your construction career goals.

Work Environment and Day‑to‑Day Conditions

Where plumbers work

Plumbers primarily serve residential and commercial customers. They may install plumbing systems during new construction or perform maintenance and repairs in existing buildings. Worksites include homes, offices, hospitals, restaurants, and schools. Since plumbing emergencies don’t follow a 9‑to‑5 schedule, plumbers often work nights and weekends and are frequently on call. The BLS reports that self‑employment is common; about 8% of plumbers, pipefitters, and steamfitters were self‑employed in 2024.

Where pipefitters work

Pipefitters typically work in industrial settings—manufacturing plants, refineries, power stations, shipyards, and large commercial buildings.
