Thinking about a career as a plumber but worried about spending years in school? You’re not alone. Many Americans assume skilled trades require a 4-year degree—but that’s not true for plumbing. In fact, becoming a licensed plumber is often faster, more affordable, and just as lucrative as many college paths. So, how many years of school to be a plumber? The answer might surprise you—and it could be your ticket to a stable, well-paying job with strong job security.
What Education Do You Need to Become a Plumber?
Most people are relieved to learn that you don’t need a traditional college degree to become a plumber. Instead, the plumbing profession relies on a combination of technical training and hands-on apprenticeship. This model prioritizes real-world experience over classroom theory—perfect for those who learn by doing.
According to the U.S. Bureau of Labor Statistics (BLS), most plumbers complete a 4- to 5-year apprenticeship program, which includes at least 144 hours of classroom instruction and 2,000 hours of paid on-the-job training per year.
So while there is some “school” involved, it’s not like sitting through lectures for years. Think of it more as earning while you learn.
💡 Pro Tip: Many plumbing apprenticeships are sponsored by unions (like the United Association) or private contractors—and often cost nothing upfront.
Step-by-Step: How to Become a Plumber in the U.S.
Here’s the typical path, broken into clear, actionable steps:
1. Earn a High School Diploma or GED (0–1 Year)
This is your starting point. Focus on math (especially geometry and algebra), science, and shop classes if available. Strong reading and communication skills also matter—you’ll be reading blueprints and talking to clients.
2. Enroll in a Plumbing Trade School (Optional but Helpful – 6 Months to 2 Years)
While not always required, attending a vocational or technical school gives you a head start. Programs like those at Lincoln Tech or local community colleges typically last 6 months to 2 years and cover:
- Pipefitting
- Drainage systems
- Local plumbing codes
- Safety protocols
These programs often help you qualify for better apprenticeships.

3. Complete a Plumbing Apprenticeship (4–5 Years)
This is the core of your training. You’ll work under a licensed plumber while attending night classes. Most apprenticeships include:
- 8,000–10,000 total on-the-job hours
- 576–720 classroom hours over the program
- Pay that starts at 40–50% of a journeyman’s wage and increases yearly
Apprenticeships are competitive—apply early and network with local contractors.
4. Get Licensed (Varies by State)
After your apprenticeship, you’ll need to pass a licensing exam. Requirements differ by state:
- Most states require 2–4 years of experience post-apprenticeship to become a Master Plumber
- Some states (like Kansas or Missouri) have no statewide licensing, but local counties may still require it
Check your state’s rules via the Plumbing-Heating-Cooling Contractors Association (PHCC) .
How Long Does It Really Take? A Quick Comparison
| Traditional College (BS) | 4+ years | $40,000–$100,000+ | Degree (not required for plumbing) |
| Trade School Only | 6–24 months | $3,000–$15,000 | Certificate or diploma |
| Apprenticeship (Most Common) | 4–5 years | $0(paid training) | Journeyman license + full-time job |
| Fast-Track Programs | 8–12 months | $5,000–$10,000 | Entry-level helper role |
💡 Reality Check: The 4–5 year apprenticeship remains the gold standard. It’s free, paid, and leads directly to licensure.
Do You Really Need to Go to “School”?
Technically, yes—but not in the way you think. The “school” part of plumbing training usually means:
- Night classes during your apprenticeship (1–2 evenings per week)
- Online modules on code updates or new technologies
- Safety certifications (like OSHA 10)
You won’t be writing essays or taking finals in literature. Instead, you’ll study IPC (International Plumbing Code), pipe sizing charts, and water pressure calculations.
And remember: experience counts more than degrees in this field. A plumber with 10,000 hours on the job is far more valuable than someone with a certificate but no real-world practice.
Pros and Cons of a Plumbing Career Path
✅ Pros:
- High demand: BLS projects 2% job growth through 2032, with over 50,000 openings yearly due to retirements.
- Strong earnings: Median wage is $60,090/year (2023), with top earners making $100,000+.
- Job security: People always need running water and working toilets—recession-proof!
- Entrepreneurship: Many plumbers start their own businesses after 5–10 years.
❌ Cons:
- Physical work: You’ll crawl in tight spaces, lift heavy materials, and work in all weather.
- On-call hours: Emergencies like burst pipes happen at 2 a.m.
- Licensing hurdles: Rules vary by state—moving can mean re-certifying.
Still, for many, the pros far outweigh the cons.
How Much Does Plumbing School Cost?
If you choose trade school (before or during an apprenticeship), expect to pay:
- Community College Certificate: $1,000–$5,000
- Private Trade School: $5,000–$15,000
- Apprenticeship Tuition: Often $0—sponsored by unions or employers
Compare that to the average $30,000+ student debt for a 4-year degree—and plumbing starts looking like a smart financial move.
FAQ: Common Questions About Plumbing School & Training
Q: Can I become a plumber without going to school?
A: Yes—but you’ll still need training. Most states require an apprenticeship (which includes classroom hours) to get licensed. You can’t just start working independently without credentials.
Q: How many years of school to be a plumber in California (or Texas, Florida, etc.)?
A: Most states follow the 4–5 year apprenticeship model. California requires 4 years (7,600 hours OJT + 576 classroom hours). Texas has no state license but requires local registration—training still takes 4+ years for full proficiency.
Q: Is plumbing school hard?
A: It’s challenging but manageable. You need basic math and problem-solving skills. The hardest part is often the physical labor—not the coursework.
Q: Can I finish faster with online plumbing courses?
A: Online courses can help with theory, but hands-on hours are mandatory for licensing. No state accepts 100% online training for full licensure.
Q: Do plumbers make good money?
A: Absolutely. The top 10% earn over $100,000/year, especially in metro areas like NYC, San Francisco, or Seattle. Self-employed plumbers often earn more after building a client base.
Q: What’s the difference between an apprentice, journeyman, and master plumber?
A:
- Apprentice: In training (0–5 years experience)
- Journeyman: Licensed to work independently (after passing exam)
- Master Plumber: Can design systems, pull permits, and run a business (requires 2+ years as journeyman + advanced exam)
Conclusion: A Smart, Fast Track to a Rewarding Career
So, how many years of school to be a plumber? Technically, 0–2 years of formal school—but 4–5 years of paid, hands-on training through an apprenticeship. That’s far less time and debt than a traditional degree—and with equally strong (or better) earning potential.
Plumbing offers job stability, upward mobility, and real-world impact. Whether you’re a high school grad, a career changer, or a parent seeking a reliable trade, plumbing could be your perfect fit.
