What Is the Difference Between Plumbers and Pipefitters?

Plumbing and pipefitting are two distinct trades in the construction industry. Without a well-functioning piping system, a clean water supply and proper wastewater disposal would be impossible. 

Both types of skilled tradesmen are crucial in ensuring piping systems are correctly installed, working efficiently, and maintained as years go by. But what is the difference between a plumber and a pipefitter? Let’s dive into the details below. 

What Do Plumbers and Pipefitters Do?

The Bureau of Labor Statistics categorizes plumbers and pipefitters under the same category but each carries out different functions.

Plumbers can work independently or be hired by a company. Their main task is to install and repair water pipes, gas lines, and drainage systems. Repairing fixtures such as bathtubs and toilets are everyday tasks performed by plumbers. 

A pipefitter’s workplace is in factories and power plants where they install high-pressure steam lines and transport pipes. Common tasks that a pipefitter usually performs are maintenance and repairs of industrial piping systems. 

What Is the Difference Between Plumbers and Pipefitters?

Differences based on the skills required 

What is the difference between a plumber and a pipefitter in terms of skills? Let’s start with the working environment. 

Pipefitters primarily work in industrial settings such as factories, refineries, and offshore installations. Plumbers, on the other hand, work in residential and commercial buildings. 

Plumbers install, repair and maintain fixtures, water pipes, and other equipment you’ll typically find in homes and business establishments. Other tasks involved are the installation of gas lines and some appliances for your bathroom or kitchen. For pipefitters, it’s all about transporting or installing liquids, gases, tanks, pumps, and other industrial apparatuses. 

Differences based on training and education 

Apprenticeship programs are available for both kinds of tradesmen. Plumbers and pipe fitters both require four to five years of apprenticeship but have different training requirements. 

Pipefitter training involves more industrial tasks like working in steam plants with a greater emphasis on physics and math. 

Plumbers will tackle properly handling water systems and also must learn math, physics, and analytical thinking. Joining pipes might require additional education about welding, brazing, and soldering. 

Differences based on the scope of work

Plumbers will primarily work in new constructions or buildings and follow local state building codes. Other tasks include maintaining systems, clearing clogged drains, repairing damaged pipes, and fixing leaks. They are also skilled in testing plumbing systems, inspecting for damages, and removing damaged fixtures. 

For pipe fitters, it’s all about installing and repairing pipes. They will need to be able to determine pipe sizes required for the installation, lay out piping systems, and join pipes together. Installing or maintaining valves and regulators to control gas and liquids are also some of their typical daily tasks. 

Differences based on the work environment 

Plumbers primarily work in domestic settings, while pipe fitters work in commercial or industrial spaces. Plumbers will need to work on pipes in crawlspaces or attics. On the other hand, pipe fitters will be in larger areas such as boiler rooms and power plants. 

Health hazards for plumbers include mold and asbestos exposure. For pipe fitters, welding fumes and chemicals are not uncommon hazards. 

Differences based on salary and job outlook

Plumber vs. Pipefitter: Whom Should You Hire?

For commercial buildings or industrial plants, a pipe fitter would be the best person for the job. They are more adept in handling large piping systems carrying chemicals, gas, or water, and a pipe fitter would better understand the blueprints from these piping systems. 

A plumber will better handle more minor projects in business establishments or homes. Blueprints for these types of piping systems will be better interpreted by a plumber to properly carry gas, water, and waste in your household or establishment.
