Thinking about a hands-on, in-demand career with strong earning potential? You’re not alone. Many Americans are turning to skilled trades like plumbing for job security, flexibility, and the satisfaction of solving real-world problems. But before you grab your wrench, it’s essential to understand what are the requirements to become a plumber—from education and apprenticeships to state licensing rules. This guide breaks it all down clearly, so you can start your journey with confidence.
What Does a Plumber Actually Do?
Before diving into the requirements, let’s clarify the role. Plumbers install, repair, and maintain pipes, fixtures, and systems that carry water, gas, and waste in residential, commercial, and industrial settings. They troubleshoot leaks, unclog drains, read blueprints, and ensure systems comply with local building codes.
According to the U.S. Bureau of Labor Statistics (BLS), employment of plumbers is projected to grow 5% from 2022 to 2032—faster than the average for all occupations—driven by new construction and aging infrastructure.
Step-by-Step: How to Become a Plumber in the U.S.
Becoming a licensed plumber typically follows a structured path. While exact rules vary by state, the core steps remain consistent nationwide.
1. Meet Basic Eligibility Requirements
Most states require you to be:
- At least 18 years old
- A U.S. citizen or legal resident
- Hold a high school diploma or GED
Strong math, mechanical aptitude, and problem-solving skills are highly beneficial. Courses in algebra, geometry, and shop classes can give you a head start.
2. Complete a Plumbing Apprenticeship (4–5 Years)
Apprenticeships are the gold standard for plumber training. They combine on-the-job training (around 2,000 hours per year) with classroom instruction (144+ hours annually).
You’ll learn:
- Pipe system design
- Local and national plumbing codes (like the International Plumbing Code)
- Safety protocols
- Blueprint reading
- Drain-waste-vent (DWV) systems
Apprenticeships are often sponsored by:
- Trade unions (e.g., United Association)
- Non-union contractor associations
- Community colleges
💡 Pro Tip: Many apprentices earn while they learn—starting at $18–$25/hour, with wages increasing as skills improve.
“An apprenticeship isn’t just training—it’s your first real job in the trade,” says Maria Lopez, a master plumber in Texas with 15 years of experience. “You’re building a reputation from day one.”
3. Obtain a Journeyman Plumber License
After completing your apprenticeship (typically 4–5 years), you can apply for a journeyman plumber license. Requirements include:
- Proof of completed apprenticeship hours
- Passing a written exam (covers codes, math, and system design)
- Paying a state-specific fee ($50–$300)
Licensing is state-regulated, so check your local board (e.g., California’s CSLB or New York’s Department of State). Some states, like Kansas or Missouri, don’t require state-level licensing—but local municipalities might.

4. Gain Experience & Consider Master Plumber Certification
After working as a journeyman for 2–5 years (depending on the state), you can pursue master plumber status. This advanced license allows you to:
- Pull permits
- Start your own plumbing business
- Supervise other plumbers
The master exam is more rigorous, often including business law and advanced system design.
Plumbing School vs. Apprenticeship: Which Is Better?
| Duration | 1–2 years | 4–5 years |
| Cost | $3,000–$15,000 | Oftenpaid(you earn while learning) |
| Hands-on Experience | Limited (lab-based) | Extensive (real job sites) |
| Job Placement | Varies by school | High (often hired by sponsor) |
| License Eligibility | May not count toward full license hours | Counts fully toward licensing |
Verdict: Most industry experts recommend starting with an apprenticeship—it’s cost-effective, practical, and directly leads to licensure.
Physical & Soft Skills Needed to Succeed
Plumbing isn’t just about pipes—it’s a blend of physical stamina and interpersonal skills.
Physical Requirements:
- Ability to lift 50+ lbs
- Comfort working in tight spaces (crawl spaces, attics)
- Standing or kneeling for long periods
Soft Skills That Matter:
- Customer service: You’ll interact with homeowners daily.
- Problem-solving: No two leaks are identical.
- Time management: Juggling multiple service calls efficiently.
How Much Do Plumbers Earn?
According to the BLS (May 2023 data):
- Median annual wage: $60,090
- Top 10% earn: Over $100,000/year
- Self-employed master plumbers in high-demand areas (e.g., California, New York) often exceed $120,000
Earnings rise significantly with experience, specialization (e.g., gas lines, medical gas systems), and geographic location.
Common Challenges (And How to Overcome Them)
- Physical demands: Stay fit and use proper lifting techniques.
- Irregular hours: Many plumbers offer emergency services—plan for weekend or night calls.
- Licensing complexity: Use your state’s plumbing board website for exact requirements. Keep detailed logs of your work hours.
