Is It Hard to Get a Plumbing License? The Real Truth Revealed

Is It Hard to Get a Plumbing License? Let’s Be Honest — It’s Challenging, But Totally Doable

You’ve been thinking about becoming a plumber. Maybe you love working with your hands. Maybe you’re tired of a 9-to-5 desk job. Or maybe you just saw a plumber fix a leak in 10 minutes and thought, “I could do that.”

But then you hit a wall: Is it hard to get a plumbing license?

The short answer? Yes — it’s not easy. But it’s absolutely achievable.

This isn’t a “click a button and get certified” kind of career. It’s one built on sweat, patience, and real-world experience. But if you’re willing to put in the work, plumbing offers one of the most stable, well-paying skilled trades in the U.S. — with median pay over $60,000 and rising.

Let’s walk through exactly what it takes — no fluff, no hype, just the real steps, hurdles, and insider tips you won’t find on a generic Google search.

How Long Does It Take to Get a Plumbing License?

Most people assume licensing happens in months. The truth? It typically takes 4–5 years.

Here’s the standard path in most U.S. states:

The U.S. Department of Labor confirms that plumbing apprenticeships are among the longest and most rigorous in the skilled trades — and for good reason. A single mistake in a water line can cause thousands in damage. You’re not just installing pipes — you’re protecting people’s homes and health.

“Plumbing is one of the few trades where you can’t afford to learn on the job — because the job is someone’s kitchen, bathroom, or basement.”
— National Association of Home Builders (NAHB)

What Are the Exact Requirements to Get Licensed?

Requirements vary by state — but here’s a universal checklist most states demand:

✅ Be at least 18 years old
✅ Have a high school diploma or GED
✅ Complete a state-approved apprenticeship program (4–5 years)
✅ Accumulate 8,000–10,000 hours of hands-on work
✅ Pass a written exam (codes, math, safety, local regulations)
✅ Pass a practical skills test (e.g., install a toilet, solder copper, pressure-test pipes)
✅ Show proof of liability insurance (required for master licenses)
✅ Pass a background check (some states require this)

Pro Tip: Some states like California and New York have extra requirements — like continuing education every 2 years. Others, like Texas, allow you to skip the apprenticeship if you have 10+ years of experience. Always check your state’s plumbing board website — not a random blog.

Is the Plumbing License Exam Really That Hard?

Yes — and no.

Let’s break it down.

Real Story: James, 29, from Ohio, failed his journeyman exam twice. He thought he knew everything — until he got tripped up on backflow prevention device installation. He hired a tutor, spent 8 weeks drilling code sections, and passed on his third try. His advice? “Don’t guess. Memorize the code numbers. They test you on specifics.”

Study Hack: Focus on these top 5 code sections:

1. Pipe sizing and pressure (Chapter 6)
2. Drain-waste-vent systems (Chapter 7)
3. Water supply and distribution (Chapter 4)
4. Fixtures and fittings (Chapter 5)
5. Backflow prevention (Chapter 10)

Most state boards offer free sample exams. Use them. Repetition is your secret weapon.

How Much Does It Cost to Get Licensed?

Here’s a realistic cost breakdown (national average):

BONUS: Many unions (like United Association) and community colleges offer paid apprenticeships. You earn while you learn — often starting at $15–$20/hour and climbing to $30+/hour by year 4.

“I didn’t have to take out a loan. My employer paid for my classes and gave me raises every 6 months.”

Pros vs. Cons: Is Becoming a Licensed Plumber Worth It?

Let’s weigh the real trade-offs.

Verdict? If you don’t mind hard work and want a career that never goes out of style — yes, it’s worth it.

Can You Get a Plumbing License Without an Apprenticeship?

Rarely — and it’s risky.

Only a handful of states allow “experience-only” paths — and even then, you need 10+ years of documented, verifiable work under a licensed plumber.

Example:

• Texas: 4 years of experience + 10,000 hours → eligible for journeyman exam
• Florida: 4 years as a registered plumber + 2 years as a contractor → master license
• California: No apprenticeship required, but you must pass a 175-question exam + provide 4 years of payroll records

Warning: Avoid “fast track” programs online that promise “license in 30 days.” These are scams. Legitimate licensing is regulated by state boards — not YouTube influencers.

If you’re short on time, consider starting as a helper (no license needed) and finding a union or contractor who’ll train you. It’s the fastest legitimate route.

FAQ: Your Top Plumbing License Questions — Answered

Q1: Do I need a college degree to become a plumber?

No. A high school diploma or GED is all you need. Many plumbers never went to college. Trade schools and apprenticeships are your real path. In fact, the average plumber earns more than the average college graduate in their first 5 years.

Q2: Can I get a plumbing license if I have a criminal record?

It depends. Most states allow it unless you have fraud, theft, or violent crime convictions. Some states (like Illinois) require a hearing. Always disclose everything — hiding it will get your application denied or revoked later.

Q3: How often do I have to renew my plumbing license?

Every 2–3 years in most states. Renewal usually costs $50–$150 and requires 8–16 hours of continuing education (e.g., new codes, safety updates). Some states offer free online courses through community colleges.

Q4: What’s the difference between a journeyman and master plumber?

• Journeyman: Can work independently under a master’s supervision. Can pull permits for residential jobs.
• Master: Can start a business, hire journeymen, pull commercial permits, and sign off on inspections. Master licenses are required if you want to be your own boss.

Q5: Can I get licensed if I’m over 40?

Absolutely. The average age of a new plumber is 38. Many people switch careers in their 40s and 50s. Plumbing values skill over age. In fact, older apprentices often bring better work ethic and problem-solving skills.

Q6: Is there a test for women? Do they get hired?

There’s no gender test — and yes, women are hired. Female plumbers are still a minority (only 3% of the workforce), but demand is rising. Organizations like Women in Plumbing and Plumbing & HVAC Women’s Network offer mentorship. If you’re capable, you’ll be welcomed.

Final Thoughts: Yes, It’s Hard — But Your Future Self Will Thank You
