What Does a Plumber Do?

Plumbers install, repair, and maintain the pipes, fixtures, and systems that carry water, gas, and waste throughout residential, commercial, and industrial buildings. On a typical day, a plumber might read blueprints to plan pipe layouts, cut and join pipes using soldering or welding techniques, install appliances such as water heaters and dishwashers, and diagnose leaks or blockages using specialized testing equipment. The work takes place across a wide variety of settings, including new construction sites, private homes, office buildings, and factories. Plumbers frequently work in tight or confined spaces such as crawlspaces and utility rooms, and they may be called out for emergency repairs during evenings or weekends.

This career suits people who enjoy hands-on problem-solving, have good physical stamina, and take satisfaction in providing an essential service to their community. Strong attention to detail and the ability to read technical diagrams are key traits for success in the field. Most employers require High school diploma or equivalent to enter the trade, typically through an apprenticeship program that combines on-the-job training with classroom instruction. Job outlook for plumbers is strong, driven by ongoing construction activity and the need to upgrade aging infrastructure in many cities. The median annual wage for plumbers is $61,550, with experienced master plumbers and those who run their own businesses often earning considerably more.

Education & Requirements

1
Complete Your Basic Education

Earn a High school diploma or equivalent or equivalent qualification. This foundational step ensures you have the basic math, reading, and technical skills required to enter a plumbing training program or apprenticeship.

2
Enroll in a Vocational or Trade Program

After obtaining your High school diploma or equivalent, consider attending a vocational school or community college that offers plumbing-related courses. These programs cover pipe systems, blueprints, safety codes, and basic plumbing techniques to prepare you for hands-on work.

3
Complete an Apprenticeship

Join a formal apprenticeship program, typically lasting 4 to 5 years, sponsored by a union or plumbing contractor. Most programs require at least a High school diploma or equivalent for entry. You will gain paid, hands-on experience working alongside licensed plumbers in real job settings.

4
Obtain Your Journeyman Plumber License

After completing your apprenticeship, pass your state's journeyman plumber licensing exam. Requirements vary by state but generally include proof of your High school diploma or equivalent, documented work hours, and a written test covering plumbing codes and safety regulations.

5
Advance to Master Plumber Status

With several years of journeyman experience, you can pursue a master plumber license, allowing you to run your own business and oversee other plumbers. Continuing education beyond your High school diploma or equivalent and initial training can further strengthen your expertise and career opportunities.

Job Outlook

The job outlook for plumbers remains exceptionally strong, with employment projected to grow by +6% over the next decade — outpacing the average for all occupations. This robust demand is driven by an aging national infrastructure that requires constant repair and upgrades, a surge in residential and commercial construction, and the growing need for water-efficient and green building systems. As older plumbers retire, a significant skills gap is emerging, making it an ideal time for new workers to enter the trade. Approximately 51,600 job openings are expected each year, stemming from both industry expansion and the need to replace an experienced workforce that is steadily aging out of the field.

Plumbers find employment across a wide range of sectors, including residential construction firms, commercial contractors, industrial facilities, government agencies, and utility companies, while many experienced tradespeople choose to operate their own independent businesses. The median annual wage for plumbers stands at $61,550, though earnings can climb considerably higher depending on specialization and location. Geographically, the strongest job markets tend to be in fast-growing Sun Belt states like Texas, Florida, and Arizona, as well as densely populated urban corridors along the coasts where construction activity remains high. Specialty areas such as pipefitting, steamfitting, sprinkler system installation, and medical gas piping command premium wages and offer some of the most competitive career advancement opportunities within the broader plumbing profession.
