Do You Have To Go to Trade School for Plumbing?

Thinking about becoming a plumber but unsure if trade school is mandatory? You’re not alone. Many aspiring tradespeople ask, “Do you have to go to trade school for plumbing?”—especially when weighing time, cost, and career outcomes. The good news? There’s more than one path to success in this in-demand field. Let’s break down your options clearly and help you make an informed decision.

What Exactly Is Trade School for Plumbing?

Trade schools (also called vocational or technical schools) offer focused, hands-on training in specific skilled trades—plumbing included. Programs typically last 6 months to 2 years and combine classroom learning with practical lab work.

Unlike a 4-year college, trade school skips general education requirements and dives straight into pipefitting, blueprint reading, local plumbing codes, and tool mastery.

According to the U.S. Bureau of Labor Statistics (BLS), employment of plumbers is projected to grow 4% from 2024 to 2034—faster than average—thanks to aging infrastructure and new construction. That makes now a smart time to enter the field.

Do You Really Need Trade School to Become a Plumber?

Short answer: No—but it helps immensely.

While trade school isn’t legally required in most U.S. states to become a plumber, licensing almost always is. And to qualify for a plumbing license, you usually need a combination of education and hands-on experience—typically 2,000–8,000 hours of apprenticeship work.

So while you could skip trade school and go straight into an apprenticeship, doing so without foundational knowledge can make the learning curve steeper (and slower).

“Apprentices who’ve had prior classroom training tend to grasp code requirements and safety protocols faster,” says Mike Smith, a master plumber and instructor at the Plumbing-Heating-Cooling Contractors Association (PHCC).

Alternative Paths: Apprenticeship vs. Trade School

💡 Pro Tip: Many union-sponsored apprenticeships (like those from UA Local 125 or UA Local 393) actually prefer candidates with some trade school background—it shows commitment and basic knowledge.

What You’ll Learn in Plumbing Trade School

If you choose trade school, expect a structured curriculum like this:

1. Plumbing Fundamentals
   • Pipe types (PVC, copper, PEX)
   • Fitting and soldering techniques
   • Drain-waste-vent (DWV) systems
2. Blueprint Reading & Math
   • Interpreting architectural plans
   • Calculating pipe lengths, slopes (typically ¼” per foot for drains)
3. Local & National Codes
   • Uniform Plumbing Code (UPC) or International Plumbing Code (IPC)
   • State-specific regulations (e.g., backflow prevention in California)
4. Safety & Tool Use
   • OSHA-10 certification (often included)
   • Proper use of pipe cutters, torches, and pressure testers
5. Green Plumbing & Technology
   • Water-saving fixtures
   • Smart leak detection systems

Most reputable programs also prepare you for the journeyman plumber exam—a key step toward licensure.

Step-by-Step: How to Become a Plumber (With or Without Trade School)

Option A: Start with Trade School

1. Research accredited programs (look for ACCSC or ABET accreditation).
2. Complete a 1–2 year diploma/certificate program (~$8,000 average cost).
3. Apply for a plumbing apprenticeship (many schools have partnerships).
4. Work 4–5 years as an apprentice (2,000–8,000 hours, depending on state).
5. Pass your state’s journeyman plumber exam.
6. Upgrade to master plumber after 2+ more years.

Option B: Go Straight to Apprenticeship

1. Find an open apprenticeship (check Job Corps, local unions, or contractors).
2. Pass basic math and reading tests (many require 8th-grade level skills).
3. Register with your state’s apprenticeship board.
4. Work and learn on the job (you’ll earn ~40–50% of a journeyman’s wage at first).
5. Take night classes (often required by state law—e.g., 144 hours/year).
6. Sit for licensing exam after required hours.

⚠️ Note: In states like New York, Florida, and Texas, you must complete formal classroom instruction—even if you’re in an apprenticeship.

Real Success Story: From High School to Licensed Plumber

Take Jamal R., 24, from Columbus, Ohio. After high school, he enrolled in a 12-month plumbing program at Columbus State Community College ($6,200 total).

During his final semester, he was hired as a paid apprentice by a local plumbing company. Two years later, he passed his journeyman exam on the first try and now earns $62,000/year—with overtime during winter emergencies pushing that higher.

“When I started on real job sites,” Jamal says, “I wasn’t lost. My classmates who skipped school kept asking me how to read isometric drawings!”

FAQ Section

Q: Can you become a plumber without any formal education?

A: Yes—but you’ll still need to complete a state-approved apprenticeship (which often includes classroom hours). Self-taught plumbers can’t legally pull permits or work independently in most states.

Q: How long does it take to become a licensed plumber?

A: Typically 4–5 years, combining apprenticeship hours and required coursework. Trade school may shorten this by giving you a head start.

Q: Is plumbing school worth the cost?

A: For most, yes. The average plumber earns $61,500/year (BLS, 2025), with top earners making $100,000+ in high-demand areas. ROI on a $10k program is usually under 12 months post-licensure.

Q: Do I need a high school diploma to enter plumbing trade school?

A: Yes—almost all accredited programs require a high school diploma or GED.

Q: Can I take plumbing courses online?

A: Partially. Theory and code classes may be online, but hands-on skills (soldering, pipe threading) require in-person labs. Fully online “plumbing certifications” are not recognized for licensing.

Q: What’s the difference between an apprentice, journeyman, and master plumber?

A:

• Apprentice: Learner under supervision (0–4 years)
• Journeyman: Licensed to work independently (after passing exam)
• Master: Can design systems, pull permits, and run a business (2+ years as journeyman required)
