Thinking about a hands-on, in-demand career that pays well and offers job security? You’re not alone. Many Americans are turning to skilled trades like plumbing—and for good reason. But before you grab your wrench, you need to know: what are the requirements to be a plumber? Whether you’re a high school grad, a career changer, or just curious, this guide breaks down everything you need—step by step, state by state—to launch a successful plumbing career in the U.S.
What Education Do You Need to Become a Plumber?
Contrary to popular belief, you don’t need a four-year college degree to become a plumber. In fact, most plumbers start with a high school diploma or GED—that’s the baseline educational requirement across all 50 states.
However, taking the right high school courses can give you a head start:
Math (especially geometry and algebra for pipe measurements)
Science (physics helps understand water pressure and flow)
Shop or vocational classes (if available)
After high school, your real training begins through one of two main paths:
Trade School or Community College Programs typically last 1–2 years and cover blueprint reading, safety protocols, local plumbing codes, and hands-on pipefitting. Tuition averages $1,000–$15,000, depending on location and program length.
Apprenticeship (Most Common Route) This is the gold standard. You earn while you learn—working under a licensed plumber for 4–5 years while attending classroom instruction (usually 144–200 hours per year). The U.S. Department of Labor reports that over 80% of plumbers enter the field through registered apprenticeships.
Yes—almost always. Plumbing directly impacts public health and safety, so all 50 states require licensure, though rules vary significantly by state and even by city or county.
Here’s a general breakdown of licensing levels:
Apprentice
High school diploma; enrolled in apprenticeship
Work under supervision only
Journeyman
4–5 years apprenticeship + pass exam
Work independently (no business ownership)
Master Plumber
2+ years as journeyman + advanced exam
Run your own business, pull permits, design systems
For example:
In Texas, you need 4,000 hours of experience to sit for the journeyman exam.
In California, you must complete a state-approved program and pass both written and practical tests.
New York City requires separate licensing even if you’re licensed elsewhere in the state.

Soft Skills:
Problem-solving: Diagnosing a clog or leak often requires detective work.
Physical stamina: You’ll crawl under houses, lift heavy materials, and work in tight spaces.
Customer service: Many plumbers interact directly with homeowners—patience and clear communication matter.
According to the Bureau of Labor Statistics (BLS), employment of plumbers is projected to grow 5% from 2022 to 2032—faster than average—driven by new construction and aging infrastructure.
How Long Does It Take to Become a Licensed Plumber?
On average: 4 to 6 years.
Here’s a realistic timeline:
Year 1: Enroll in an apprenticeship or trade school (ages 18+).
Years 2–5: Complete 2,000+ hours of paid on-the-job training per year + classroom work.
Year 5: Take your journeyman plumber exam (typically 100+ multiple-choice questions on codes, safety, and math).
Years 6–7 (optional): Gain experience and test for master plumber status.
⏱️ Fast-track option? Some states (like Florida) offer accelerated programs for military veterans or those with related construction experience.
What’s the Average Salary for Plumbers in the U.S.?
Plumbing pays well—especially with experience and specialization.
National median wage: $60,090/year (BLS, May 2023)
Top 10% earners: Over $100,000/year (often master plumbers or business owners)
Highest-paying states: Illinois, Alaska, Hawaii, New Jersey, and Massachusetts
Specializing in areas like commercial plumbing, medical gas systems, or green plumbing (water-efficient fixtures) can boost earnings further.
💰 Bonus insight: Emergency plumbers who offer 24/7 services often charge 1.5x–2x standard rates for after-hours calls.
Pros and Cons of a Plumbing Career
High demand & job security
Physically demanding work

Still, 92% of plumbers report high job satisfaction (per a 2023 Trade Careers Survey), citing autonomy, problem-solving, and tangible results as top motivators.
Step-by-Step: How to Start Your Plumbing Career Today
Earn your high school diploma or GED.
Research local plumbing programs—check community colleges or union halls (e.g., UA Local 1).
Q: Can I become a plumber without going to trade school?
A: Yes! Most plumbers learn through paid apprenticeships, not formal school. Trade school is optional but can shorten your path or strengthen your application.
Q: How much does plumbing school cost?
A: Costs range from $1,000 (short certificate programs) to $15,000 (2-year associate degrees). Many apprenticeships cost nothing—you get paid to train.
Q: Do I need to be good at math to be a plumber?
A: Basic math is essential—fractions, geometry, and unit conversions (e.g., gallons per minute). You don’t need calculus, but accuracy matters when cutting pipes or sizing drains.
Q: Can felons become plumbers?
A: It depends on the state and nature of the offense. Some states conduct background checks for licensing. Always disclose upfront and check with your state’s plumbing board.
Q: Is plumbing a good career for women?
A: Absolutely. While only ~2% of plumbers are women (BLS), organizations like Women in Plumbing and UA’s “Got Skills?” initiative actively support diversity in the trade.
Q: What’s the difference between a plumber and a pipefitter?
A: Plumbers work on water, waste, and gas systems in buildings. Pipefitters install high-pressure pipes in industrial settings (power plants, factories). Training overlaps, but certifications differ.
Conclusion
So, what are the requirements to be a plumber? A high school diploma, hands-on training (usually via apprenticeship), state licensure, and a mix of technical and interpersonal skills. It’s a career that rewards hard work, offers financial stability, and can’t be outsourced or automated.
If you’re ready to build a future with your hands—and your brain—plumbing might be your perfect fit.
