How to Become a Plumber in 2026
Plumbing is one of the most essential and highest-paying skilled trades that doesn't require a college degree. With stable 4% projected job growth through 2034, strong union wages, and growing demand from infrastructure projects and green building technology, plumbing offers a reliable career path with six-figure earning potential. Here's the complete path from apprentice to master plumber.

Step-by-Step Path to Becoming a Plumber
Step 1: Meet Basic Requirements
Before starting your plumbing career, you need:
- High school diploma or GED
- Be at least 18 years old (to enter most apprenticeship programs)
- Valid driver's license (required for most jobs)
- Basic math skills — algebra, geometry, and measurement conversions
- Physical ability — lifting 50+ lbs, working in tight spaces, standing for long periods
Helpful high school courses: algebra, physics, shop classes, mechanical drawing, and any CTE (Career and Technical Education) courses.
Step 2: Choose Your Training Path
You have two main routes into the plumbing trade:
| Path | Duration | Cost | Earnings While Training |
|---|---|---|---|
| Apprenticeship | 4–5 years | Free (you earn while you learn) | $35,000–$55,000/year |
| Trade School | 6–12 months | $3,000–$20,000 | Not paid (but faster to journeyman) |
Apprenticeships are the most common and recommended path. You work full-time under a licensed plumber while attending classroom instruction. Programs are run through:
- UA (United Association of Journeymen and Apprentices of the Plumbing and Pipe Fitting Industry) — union apprenticeships
- ABC (Associated Builders and Contractors) — non-union apprenticeships
- PHCC (Plumbing-Heating-Cooling Contractors Association) — merit-shop apprenticeships
- State-run programs — registered with the Department of Labor
Each year of apprenticeship includes:
- 2,000 hours of paid on-the-job training
- 144+ hours of classroom instruction
- Progressive wage increases (typically 40-50% of journeyman rate to start, increasing each year)
Trade School is faster but costs money upfront. Programs cover plumbing theory, pipefitting, blueprint reading, codes, and safety. After graduation, you still need on-the-job hours before qualifying for a journeyman license.
Fast Track vs. Full License: You can start earning as a plumber's helper or pre-apprentice in as little as 3–6 months through a pre-apprenticeship program. However, becoming a fully licensed journeyman plumber requires 4–5 years and 8,000+ documented hours. There are no shortcuts to the license, but there are shortcuts to the first paycheck.
Step 3: Complete Your Apprenticeship (4–5 Years)
During your apprenticeship, you'll learn:
| Year | Focus Areas | Typical Wage (% of Journeyman Rate) |
|---|---|---|
| Year 1 | Basic plumbing tools, safety, pipe cutting, drain cleaning | 40–50% |
| Year 2 | Residential plumbing systems, fixture installation, water supply | 50–60% |
| Year 3 | Commercial plumbing, welding/soldering, gas piping | 60–70% |
| Year 4 | Blueprint reading, code compliance, system design | 70–80% |
| Year 5 (if required) | Advanced systems, medical gas, backflow prevention, exam prep | 80–90% |
Tool Investment: Plan to spend $300–$600 on your first tool bag. Essentials include pipe wrenches, basin wrench, tubing cutter, hacksaw, propane torch, adjustable wrenches, plunger, snake, and a level. Quality brands (Ridge Tool, Milwaukee, DeWalt, Reed) last decades.
Step 4: Pass the Journeyman Plumber Exam
After completing your apprenticeship hours, you must pass a journeyman plumber exam to get your license. Requirements vary by state, but most exams cover:
| Exam Topic | Approximate % |
|---|---|
| Plumbing Code (UPC/IPC) | 40–50% |
| Pipe Systems & Materials | 15–20% |
| Fixtures & Appliances | 10–15% |
| Drainage, Waste & Vent (DWV) | 10–15% |
| Water Supply & Distribution | 10–15% |
| Safety & OSHA | 5–10% |
| Exam Detail | Information |
|---|---|
| Questions | 60–100 multiple-choice |
| Time | 3–5 hours |
| Passing Score | 70–75% (varies by state) |
| Cost | $30–$150 |
| Reference | Plumbing codebook allowed (open-book in most states) |
| Prerequisites | 4,000–8,000+ hours of documented experience |
Important: Some states use the Uniform Plumbing Code (UPC) while others use the International Plumbing Code (IPC). Check your state's licensing board for which code applies. States like California, Oregon, and Washington use UPC, while Texas, Florida, and New York use IPC.
Step 5: Advance to Master Plumber (Optional but Recommended)
After 2–4+ years as a licensed journeyman, you can qualify for the master plumber exam. Master plumbers can:
- Pull permits for plumbing work
- Supervise journeymen and apprentices
- Start their own plumbing contracting business
- Earn significantly higher pay
- Perform more complex work (medical gas, backflow prevention assembly testing)
| Master Exam Detail | Information |
|---|---|
| Prerequisites | 2–4 years as licensed journeyman (varies by state) |
| Questions | 80–120 |
| Topics | Advanced plumbing code, system design, business/law, medical gas |
| Passing Score | 70–75% |
| Cost | $50–$200 |

Plumbing Specializations
Residential Plumbing
The most common path. You'll install and repair water supply lines, drainage systems, fixtures, and appliances in homes and apartments. Good mix of new construction and service/repair work.
Commercial Plumbing
Larger-scale projects in office buildings, hospitals, schools, and factories. Requires knowledge of commercial codes, larger pipe sizes, and more complex systems. Higher pay than residential.
Pipefitting & Steamfitting
Installing and maintaining high-pressure pipe systems in industrial settings. Requires additional training in welding, blueprint reading, and system testing. Among the highest-paid plumbing specializations.
Gas Piping
Installing natural gas and propane lines. Requires knowledge of fuel gas codes and usually a separate license or certification. Strong demand with the expansion of natural gas infrastructure.
Medical Gas
Installing medical gas systems (oxygen, nitrous oxide, medical air, vacuum) in hospitals and healthcare facilities. Requires NFPA 99 certification. High pay due to the critical nature of the work.
Backflow Prevention
Testing and certifying backflow prevention assemblies to protect potable water supplies. Requires a separate tester certification. Recurring annual testing contracts provide steady income.
State Licensing Requirements
Most states require a plumber's license to work independently. Here's how it breaks down:
| States With Licensing | Most states require journeyman/master plumber licenses | | States Without State Licensing | Kansas, Missouri, Nebraska, New York, Pennsylvania, Wyoming (local licenses may apply) | | Reciprocity | Some states honor licenses from other states — check with your state board |
Typical licensing requirements:
- Completion of approved apprenticeship (4–5 years)
- Passing a journeyman plumber exam
- Continuing education (8–24 hours per renewal cycle)
