Thinking about a hands-on, in-demand career that pays well and offers job security? You’re not alone. Many Americans are turning to skilled trades like plumbing as a smart alternative to traditional four-year degrees. But what do you need to become a plumber? The path involves training, licensing, physical stamina, and the right mindset—but it’s more accessible than you might think. In this guide, we’ll walk you through every essential step, tool, and trait you’ll need to launch a successful plumbing career in the U.S.
What Qualifications Do You Need to Become a Plumber?
Becoming a plumber doesn’t require a college degree—but it does require structured training and certification. According to the U.S. Bureau of Labor Statistics (BLS), most plumbers learn their trade through a 4- to 5-year apprenticeship program that combines paid on-the-job training with classroom instruction.
Key qualifications include:
High school diploma or GED (minimum requirement to enter most apprenticeships)
Strong math and problem-solving skills (for measuring, calculating pipe angles, and reading blueprints)
Basic mechanical aptitude (understanding how systems like water pressure and drainage work)
Many aspiring plumbers also take vocational courses in high school or at community colleges to get a head start. These programs often cover safety protocols, pipefitting, and local plumbing codes.
💡 Pro Tip: Completing a pre-apprenticeship program can significantly boost your chances of being accepted into a competitive union or non-union apprenticeship.
How Do You Get Licensed as a Plumber?
Licensing requirements vary by state, but nearly all U.S. states require plumbers to be licensed to work independently. The process typically follows this sequence:
Complete an apprenticeship (4–5 years under a licensed plumber)
Pass a journeyman plumber exam (covers local codes, safety, and technical knowledge)
Work as a journeyman for 1–2+ years (varies by state)
Pass a master plumber exam (to run your own business or supervise others)
For example:
In Texas, you need 4 years of experience + exam to become a journeyman.
In California, you must pass both a written and practical exam administered by the state.
While your employer or apprenticeship sponsor often provides major tools early on, you’ll eventually need your own basic toolkit. Here’s a starter list:
Pipe wrench
Grips and turns pipes
Tubing cutter
Cuts copper or plastic pipes cleanly
Plunger & drain snake
Clears clogs
Pipe threader
Creates threads on metal pipes
Level & tape measure
Ensures accurate installations
Safety goggles & gloves
Protects against debris and chemicals
Expect to invest $300–$800 in your initial toolkit. Many trade schools and unions offer tool packages for new apprentices.
What Personal Traits Make a Great Plumber?
Technical skills matter—but so does your attitude. Top plumbers share these traits:
Problem-solving mindset: Every job is a puzzle—leaks, blockages, outdated systems.
Physical stamina: You’ll crawl under houses, lift heavy materials, and stand for hours.
Customer service skills: You’re often in people’s homes during stressful situations (e.g., burst pipes). Patience and professionalism go a long way.
Attention to detail: A small measurement error can lead to major leaks or code violations.
As master plumber James Rivera (20+ years in Chicago) puts it:
“It’s not just about fixing pipes—it’s about earning trust. People let you into their most private spaces. You’ve got to be reliable, clean, and honest.”
How Much Does It Cost to Train as a Plumber?
One of the biggest advantages of plumbing? You earn while you learn.
Apprenticeships typically pay 40–60% of a journeyman’s wage from day one—often $15–$25/hour depending on location.
Most programs have low or no tuition costs (some even cover books and fees).
Trade school programs (non-apprenticeship) can cost $1,000–$15,000, but lack the paid work experience.
Compare that to the average $30,000+ student debt from a 4-year degree—and you see why plumbing is a financially smart path.
Average Earnings (BLS, 2023):
Journeyman plumber: $59,880/year median
Top 10% earners: Over $100,000/year (especially in urban areas or with specialties like gas fitting or commercial plumbing)
Pros and Cons of a Plumbing Career
Before you commit, weigh the realities:
High demand (14% job growth projected by 2031)
Physically demanding work
No student debt (in most cases)
On-call or emergency hours
Entrepreneurial opportunities
Exposure to dirty or hazardous conditions
Job security (people always need plumbing!)
Requires continuous learning (codes change)
Still, 87% of tradespeople report high job satisfaction (National Center for Construction Education & Research, 2022)—mainly due to autonomy, tangible results, and stable income.

Most successful plumbers say the first year is the toughest—but the payoff is worth it.
A: No. A high school diploma or GED is sufficient. Most training happens through paid apprenticeships, not college.
Q: How long does it take to become a licensed plumber?
A: Typically 4–5 years to become a journeyman. Adding 1–2 more years of experience allows you to test for a master plumber license.
Q: Can I become a plumber if I’m not good at math?
A: You don’t need advanced math—but basic arithmetic, fractions, and geometry are essential for measuring, cutting, and installing pipes accurately. Most apprenticeship programs include math training.
Q: Is plumbing a good career for women?
A: Absolutely. While historically male-dominated, the industry is actively recruiting women. Organizations like Women in Plumbing and NAWIC offer support, mentorship, and scholarships.
