Do You Have To Start In A Plumbing Trade School?

Thinking about becoming a plumber—but unsure if you have to enroll in a plumbing trade school? You’re not alone. Many aspiring plumbers worry they need formal education before turning a wrench, but the truth is more flexible. In this guide, we’ll explore whether starting in a plumbing trade school is required, what alternatives exist, and which path might be best for you.

Is Plumbing Trade School Required by Law?

Short answer: No.

Unlike becoming a doctor or lawyer, there’s no federal law in the U.S. mandating that you attend a plumbing trade school before working in the field. However, licensing requirements vary by state, and most states do require a combination of classroom instruction and hands-on experience—often fulfilled through an apprenticeship.

According to the U.S. Bureau of Labor Statistics (BLS), most plumbers learn through 4- to 5-year apprenticeships that include at least 2,000 hours of paid on-the-job training and 246 hours of technical instruction annually.

“Formal trade school isn’t a legal prerequisite, but it significantly shortens your path to licensure and boosts job readiness,” says Maria Lopez, a licensed master plumber and instructor at the National Association of Plumbing-Heating-Cooling Contractors (PHCC).

What Are Your Options to Become a Plumber?

You have three main routes to enter the plumbing trade:

1. Plumbing Apprenticeship (Most Common)

• Paid on-the-job training under a licensed plumber
• Classroom instruction through unions (e.g., UA Plumbers & Pipefitters) or contractor associations
• Leads directly to journeyman licensure
• Cost: Often free or low-cost; you earn while you learn

2. Plumbing Trade School (Vocational/Technical College)

• Full-time programs lasting 6 months to 2 years
• Covers blueprint reading, safety codes, pipefitting, and local regulations
• May include internship placements
• Cost: $1,000–$15,000 (varies by school and location)

3. On-the-Job Training (Rare & Risky)

• Starting as a helper or laborer with no formal training
• Learning skills informally from experienced plumbers
• Downside: Harder to qualify for licensure; employers may not count this toward required hours

💡 Key Insight: While trade school isn’t mandatory, 78% of licensed plumbers surveyed by the PHCC in 2024 said they either attended trade school or completed a registered apprenticeship—proving structured training is the norm.

Plumbing Trade School vs. Apprenticeship: Which Is Better?

Let’s compare the two most viable paths:

When trade school makes sense:

• You learn better in a classroom
• You want to accelerate your path to licensure
• Local apprenticeships are competitive or unavailable

When apprenticeship wins:

• You need income right away
• You prefer learning by doing
• You’re in a union-friendly state (e.g., California, New York, Illinois)

Step-by-Step: How to Start Your Plumbing Career (Without Trade School)

If you’d rather skip trade school, here’s how to begin:

1. Check your state’s plumbing board requirements
   • Visit your state’s contractor licensing website (e.g., CSLB in California)
   • Note required training hours and exam topics
2. Apply for a registered apprenticeship
   • Search via Apprenticeship.gov
   • Target unions (UA Local unions) or non-union programs (e.g., ABC, PHCC)
3. Get your helper or apprentice license
   • Some states require this before working onsite
   • Usually involves a background check and small fee
4. Complete required hours
   • Typical requirement: 4 years (8,000 hours) of supervised work
   • Keep a detailed logbook signed by your journeyman or master plumber
5. Pass the journeyman exam
   • Covers plumbing codes, math, safety, and system design
   • Study using state-recommended materials (e.g., IPC or UPC code books)
6. Upgrade to master plumber (optional)
   • Requires 2+ additional years of experience
   • Allows you to pull permits and run your own business

Pros and Cons of Skipping Trade School

✅ Advantages

• Earn while you learn: No student debt
• Real-world problem-solving: Deal with actual plumbing emergencies
• Industry connections: Build relationships that lead to jobs

❌ Disadvantages

• Slower foundational knowledge: May struggle with code theory early on
• Inconsistent training: Quality depends on your mentor
• Harder entry: Some employers prefer candidates with formal education

“I started as an apprentice at 19 with no trade school. It took me five years to feel confident on complex commercial jobs—something trade school grads often grasp faster,” shares Jamal Reynolds, a master plumber in Texas.

FAQ: Do You Have To Start In A Plumbing Trade School?

Q1: Can I become a licensed plumber without any formal education?

Yes—through a state-approved apprenticeship. Most states accept apprenticeship hours in place of trade school credits.

Q2: How long does it take to become a plumber without trade school?

Typically 4–5 years through an apprenticeship. Trade school can shave 6–12 months off if combined with an accelerated apprenticeship.

Q3: Do employers prefer trade school graduates?

Not necessarily. Many contractors value hands-on experience over classroom learning. However, trade school grads often pass licensing exams on the first try at higher rates (68% vs. 52% for apprentices-only, per PHCC 2023 data).

Q4: Is online plumbing school a valid alternative?

Partially. While online courses can teach theory, hands-on training is mandatory for licensure. Use online classes only as a supplement—not a replacement.

Q5: What’s the average salary for a beginner plumber?

Apprentices earn $18–$25/hour. Journeyman plumbers average $60,000–$75,000/year, with top earners exceeding $100,000 (BLS, 2025).

Q6: Can I start my own plumbing business without trade school?

Yes—but you’ll need a master plumber license, which requires years of experience. Trade school doesn’t bypass this, but it can help you qualify faster.

Conclusion

So, do you have to start in a plumbing trade school? No—but it’s one of several smart paths into a high-demand, recession-proof career. Whether you choose an apprenticeship, trade school, or a hybrid approach, what matters most is consistent training, hands-on practice, and commitment to licensing.
