How Long Does It Take to Retrain as a Plumber?

Thinking about a career change but unsure how long it’ll take to become a plumber? You’re not alone. Many adults seek stable, hands-on careers with strong job prospects—and plumbing delivers. The good news? How long does it take to retrain as a plumber depends on your path, location, and commitment—but most people can launch their new career in 1–4 years. Let’s break it down clearly so you can plan with confidence.

How Long Does It Take to Retrain as a Plumber? (The Short Answer)

For most adults switching careers, retraining as a plumber typically takes between 1 and 4 years. This includes classroom learning, hands-on training, and often a state-required apprenticeship. Unlike traditional college degrees that take 4+ years, plumbing offers a faster, debt-light route into a high-demand trade.

According to the U.S. Bureau of Labor Statistics (BLS), employment of plumbers is projected to grow 5% from 2024 to 2034—faster than average—thanks to aging infrastructure, new construction, and increasing demand for water-efficient systems.

What Are the Main Paths to Becoming a Plumber?

There are three primary routes to becoming a licensed plumber in the U.S.:

1. Apprenticeship (Most Common Path)

• Duration: 4–5 years
• Structure: Paid on-the-job training (2,000+ hours/year) + classroom instruction (144+ hours/year)
• Cost: Often free or low-cost; many employers cover training
• Outcome: Journeyman license eligibility

“An apprenticeship gives you real-world experience while earning a paycheck—something you can’t get in a classroom alone,” says Mike Smith, Master Plumber and Training Coordinator at UA Local 136.

2. Trade School + Apprenticeship

• Duration: 6 months – 2 years (school) + 2–4 years (apprenticeship)
• Structure: Accelerated technical training before entering an apprenticeship
• Cost: $3,000–$15,000 (varies by program)
• Best for: Career changers who want foundational knowledge before fieldwork

Trade schools like Tulsa Welding School or Pennsylvania College of Technology offer plumbing diplomas that can shorten your apprenticeship time in some states.

3. Fast-Track Programs (Rare & Limited Scope)

• Duration: 8–16 weeks
• Focus: Basic skills (pipefitting, drain cleaning, safety)
• Limitation: Usually leads to helper or technician roles—not full licensure
• Ideal for: Quick entry into the field while pursuing full certification

⚠️ Note: These programs don’t replace state licensing. Always verify if your state requires a formal apprenticeship for licensure. See plumbing regulations by state on Wikipedia.

State-by-State Differences: How Location Affects Timeline

Plumbing licensure is regulated at the state level, so timelines vary:

Always check your state’s plumbing board website for exact requirements. Some states allow credit for military experience or prior construction work.

Step-by-Step: How to Retrain as a Plumber (Adult Career Changer)

Follow these concrete steps to transition smoothly:

Step 1: Research Your State’s Requirements

Visit your state’s plumbing licensing board. Note required hours, exams, and fees.

Step 2: Choose Your Entry Path

• If you need income immediately → Apply for apprenticeships (e.g., through UA Plumbers & Pipefitters)
• If you prefer structured learning first → Enroll in an accredited trade school

Step 3: Apply to Programs

Most union apprenticeships open applications once a year. Non-union (merit shop) programs may accept year-round.

Step 4: Complete Required Hours

• On-the-job: 6,000–8,000 hours (≈4 years full-time)
• Classroom: 576–1,000 hours total

Step 5: Pass Licensing Exam

Exams cover plumbing codes (IPC or UPC), math, blueprint reading, and safety. Study guides are available from PSI or your state board.

Step 6: Work as a Journeyman

After licensure, you can work independently or under a master plumber.

Step 7 (Optional): Become a Master Plumber

Requires 2–5 additional years of experience + advanced exam.

FAQ Section

Q1: Can I become a plumber at 40 or older?

Absolutely. Plumbing welcomes career changers of all ages. Physical stamina matters more than age—and many tasks rely on problem-solving, not brute strength.

Q2: Do I need a high school diploma?

Yes. Most apprenticeships and trade schools require a high school diploma or GED. Basic math and reading skills are essential.

Q3: How much does plumbing training cost?

Union apprenticeships often cost nothing (sponsored by employers). Trade schools range from $3,000 to $15,000. Compare this to the average $37,000 student debt from a 4-year degree.

Q4: Can I work while training?

Yes! Apprentices earn wages from day one—typically 40–50% of a journeyman’s rate, with raises every 6–12 months.

Q5: Is online training enough?

No. While online courses (like OSHA safety certs) help, hands-on practice is mandatory for licensure. Avoid “100% online plumbing licenses”—they’re not recognized by any U.S. state.

Q6: How soon can I start earning money?

If accepted into an apprenticeship, you can start earning in 1–3 months after applying. Some programs have waiting lists, so apply early.

Conclusion

So, how long does it take to retrain as a plumber? For most dedicated adults, 2 to 4 years is realistic—and you’ll likely earn a paycheck throughout. With strong job security, low entry barriers, and growing demand, plumbing is one of the smartest second-career choices you can make.
