The short answer
Here is how to become a plumber in one paragraph: finish high school or a GED, get into a paid apprenticeship, put in 4 or 5 years of on-the-job hours plus classroom instruction, pass your state journeyman exam, then stack journey years and the master exam on top. No degree, no tuition debt, and the training pays you from day one. Every number in this guide was checked live against the Bureau of Labor Statistics, Apprenticeship.gov, and OSHA on July 10, 2026.
The trade is worth the years. The BLS counts about 504,500 plumber, pipefitter, and steamfitter jobs in 2024 and projects 4 percent growth from 2024 to 2034, with about 44,000 openings a year as workers retire or move on. The May 2025 BLS wage survey puts the median at $63,800 a year, about $30.67 an hour, with the top 10 percent above $108,420.
How to become a plumber in 8 steps
Work them in order. The hours gate the exam, and the exam gates everything else.
-
Finish high school or get a GED
Per the BLS, the typical entry education for plumbers is a high school diploma or equivalent. Apprenticeship classwork leans on mathematics, applied physics, and chemistry, so take those while they are free. Pipe sizing, drain slope, and gas work all run on that math.
-
Pick your entry point
Most apprentices apply to a program directly, per the BLS. Some start as helpers or finish a pre-apprenticeship first, and some take vocational-technical courses in pipe system design, safety, and tool use. There is no wrong door: the direct route starts the paid clock soonest, the others make your application stronger.
-
Land a paid apprenticeship
Programs are sponsored by unions, trade associations, and plumbing companies, so apply to all three. Per Apprenticeship.gov, a registered apprenticeship pays a competitive wage from day one, raises it as your skills grow, and ends in a portable, nationally recognized credential.
-
Put in the apprenticeship years
Most plumbers train through a 4 or 5 year apprenticeship, with about 2,000 hours of paid on-the-job training a year plus technical instruction in safety, local plumbing codes, and blueprint reading, per the BLS. Watch how your foreman scopes and prices work too. That habit pays later.
-
Add the OSHA 10 safety card
The 10 hour OSHA Outreach construction class covers the hazards that hurt new tradespeople, and OSHA-authorized trainers issue a completion card at the end. OSHA calls the program voluntary, and the card is not a certification, but some states, cities, and employers require it. Get it early.
-
Pass your state journeyman exam
Most states and some localities require plumbers to be licensed, and per the BLS they typically want 2 to 5 years of experience plus an exam before you work independently. Every state writes its own rules, so check your state licensing board before you count your hours. Passing makes you a journey level plumber.
-
Earn master plumber status
Plumbers with several years of plumbing experience who pass another exam earn master status, per the BLS, and some states require a master license to hold a plumbing contractor’s license and pull permits. This is the tier where the wages above $108,420 live.
-
Decide where the license takes you
Journeymen and masters move up to foreman, supervisor, and project manager roles, and some open their own shops. Running a company is its own craft with its own licensing. When you are ready for that step, our guide to how to start a plumbing business covers the entity, insurance, and pricing side.

Becoming a plumber: common questions
How long does it take to become a plumber?
Plan on 4 to 5 years to journeyman. Per the BLS, most plumbers learn through a 4 or 5 year apprenticeship with about 2,000 paid on-the-job hours a year, and states typically want 2 to 5 years of experience before licensing. Master status adds several more years of experience and another exam.
Do you need a degree to become a plumber?
No. The BLS lists a high school diploma or equivalent as the typical entry education, and the training happens inside a paid apprenticeship, not a classroom you pay for. Vocational-technical school is an optional on-ramp, not a requirement, in most programs.
How much do plumbers make?
The May 2025 BLS wage survey puts the median for plumbers, pipefitters, and steamfitters at $63,800 a year, about $30.67 an hour. The lowest 10 percent earned under $44,150 and the highest 10 percent earned above $108,420. Apprentices start lower, with raises built in as skills grow.
Can you become a plumber without an apprenticeship?
In practice, no. Per the BLS, most plumbers learn the trade through an apprenticeship, and most states require years of verified experience plus an exam before you can work independently. Helper jobs and pre-apprenticeship programs speed up entry into a program; they do not replace the hours.
