Thinking about a stable, hands-on career with strong earning potential? You’re not alone. Many Americans are turning to skilled trades like plumbing—and one of the most common questions they ask is: how many years to become a journeyman plumber? The answer isn’t one-size-fits-all, but with the right path, most people can earn their journeyman license in 4 to 5 years. Let’s break down exactly what that journey looks like, step by step.
What Is a Journeyman Plumber?
Before diving into timelines, it helps to understand what a journeyman plumber actually is. A journeyman plumber is a licensed professional who has completed formal training (usually through an apprenticeship) and passed a certification exam. Unlike apprentices, journeymen can work independently—though they still operate under the supervision of a master plumber in many states.
This role is a critical midpoint in a plumbing career: it proves you’ve mastered core skills like pipefitting, drainage systems, water supply installation, and code compliance.
How Many Years to Become a Journeyman Plumber? (The Standard Path)
In the United States, the most common route to becoming a journeyman plumber takes 4 to 5 years. This timeline includes:
- 4,000 to 8,000 hours of on-the-job training (varies by state)
- 500 to 1,000 hours of classroom instruction
- Passing a state or local licensing exam
💡 Fact: According to the U.S. Bureau of Labor Statistics (BLS), most plumbers learn their trade through a 4- to 5-year apprenticeship registered with the U.S. Department of Labor.
State-by-State Variations
While the national average is 4–5 years, requirements differ slightly depending on where you live:
| California | 8,000 | 720 | 5 years |
| Texas | 4,000 | 500 | 4 years |
| New York | 7,000 | 1,000 | 4–5 years |
| Florida | 4,800 | 600 | 4 years |

Always check your state’s plumbing board for exact requirements, as some states (like Kansas or Wyoming) have more flexible rules, while others (like Massachusetts) are stricter.
Step-by-Step: How to Become a Journeyman Plumber
Follow these concrete steps to reach journeyman status:
1. Meet Basic Eligibility Requirements
- Be at least 18 years old
- Have a high school diploma or GED
- Pass a basic math and reading assessment (some programs require this)
2. Enroll in a Plumbing Apprenticeship
Most aspiring plumbers join a registered apprenticeship program. These are often sponsored by:
- Local plumbers’ unions (like UA – United Association)
- Trade schools
- Private plumbing companies

3. Complete On-the-Job Training
You’ll work full-time (35–40 hours/week) under a licensed plumber. Tasks include:
- Installing water heaters
- Fixing leaks
- Reading blueprints
- Using pipe-cutting and threading tools
You’ll earn a wage that increases annually—starting around $18–$22/hour and rising to $28–$35/hour by year 4.
4. Attend Classroom Instruction
Typically 1 night per week or in blocks (e.g., 2 weeks per year). Topics include:
- Plumbing codes (IPC or UPC)
- Safety protocols
- Math for pipe measurements
- Backflow prevention
5. Apply for and Pass the Journeyman Exam
Once you’ve logged the required hours, you’ll sit for a licensing exam covering:
- Local and national plumbing codes
- System design
- Ventilation and drainage principles
Pass rates average 65–75% on the first try—so thorough prep is key.
Can You Become a Journeyman Plumber Faster?
In rare cases, yes—but not legally in most states. Some options that might shorten the timeline:
- Military training: Veterans with plumbing experience may get credit toward apprenticeship hours.
- Trade school credits: Completing a 2-year plumbing program at a technical college can count toward classroom hours (but you’ll still need hands-on work).
- Reciprocity agreements: If you’re licensed in one state, you might transfer credentials faster to another (e.g., between Midwest Compact states).
However, skipping required hours or exams isn’t allowed—and working without a license can result in fines or legal action.
⚠️ Beware of “fast-track” programs promising journeyman status in 6–12 months. These are often scams or only prepare you for helper roles—not licensed work.
Journeyman vs. Apprentice vs. Master Plumber: Key Differences
Understanding where you are in your career helps set realistic goals:
| Apprentice | Yes | No | $18–$25/hour |
| Journeyman | No (in most states) | Yes | $28–$40/hour |
| Master Plumber | No | Yes + supervise others | $45–$70/hour |
Once you’re a journeyman, you can:
- Bid on residential jobs
- Pull permits (in many jurisdictions)
- Start your own business (with additional licensing in some states)
Many journeymen go on to become master plumbers, which usually requires 2–5 more years of experience plus another exam.
Why the Wait Is Worth It
Becoming a journeyman plumber isn’t just about ticking boxes—it opens real doors:
- Job security: The BLS projects 5% job growth for plumbers through 2032—faster than average.
- High demand: 70% of plumbing contractors report difficulty hiring qualified workers (2024 PHCC survey).
- Earning potential: Top-earning journeymen in cities like San Francisco or Boston make $90,000+ annually.
- Entrepreneurship: With experience, you can launch your own plumbing company—like Mike Rowe’s “Dirty Jobs” success stories.
Plus, plumbing is a recession-resistant career. People always need functioning toilets, water heaters, and gas lines—no matter the economy.
FAQ: Common Questions About Becoming a Journeyman Plumber
Q: Can I become a journeyman plumber without an apprenticeship?
A: In most U.S. states, no. Formal apprenticeship (or equivalent documented experience) is legally required to sit for the journeyman exam. A few states allow “experience-only” paths, but they still demand 4+ years of verifiable work under a licensed plumber.
Q: How much does it cost to become a journeyman plumber?
A: Apprenticeships are often free or low-cost—many employers cover tuition. You’ll pay only for tools ($300–$800) and exam fees ($50–$200). Avoid for-profit schools charging $15K+ unless they offer guaranteed job placement.
Q: Do I need a college degree to be a plumber?
A: No. A high school diploma or GED is sufficient. Strong skills in math (especially fractions and geometry) and mechanical reasoning are far more valuable.
Q: Is plumbing school better than an apprenticeship?
A: Apprenticeships are generally better because you earn while you learn. Trade school can be helpful for foundational knowledge, but it doesn’t replace hands-on hours required for licensing.
Q: Can I work as a plumber while training?
A: Yes! Apprentices work full-time from Day 1, earning wages that increase yearly. You’re not just studying—you’re already part of the workforce.
Q: What’s the hardest part of becoming a journeyman plumber?
A: Most apprentices say it’s balancing work and study—especially during exam prep. Others find mastering local code variations challenging. But support from mentors and unions makes it manageable.
Conclusion: Your Plumbing Future Starts Now
So, how many years to become a journeyman plumber? Realistically, 4 to 5 years—but those years are filled with paid work, growing skills, and rising confidence. Unlike college debt, this path builds income, not bills.
If you’re ready for a career that’s in demand, pays well, and can’t be outsourced or automated, plumbing is a smart choice. And once you’re a journeyman, the sky’s the limit: specialize in green plumbing, move into commercial work, or even become your own boss.
