Thinking about a career in plumbing? Youโ€™re not alone. With strong job demand, solid pay, and hands-on work that makes a real difference, plumbing is a smart trade to pursue. But one of the first questions on every aspiring plumberโ€™s mind is: how long does it take to be a certified plumber? The answer isnโ€™t one-size-fits-allโ€”it depends on your state, training path, and dedication. In this guide, weโ€™ll walk you through every step, timeline, and requirement so you can plan your journey with confidence.


What Does โ€œCertified Plumberโ€ Actually Mean?

Before diving into timelines, itโ€™s important to clarify terminology. In the U.S., the term โ€œcertified plumberโ€ isnโ€™t universal. Most states use licensing, not certification, to regulate who can legally perform plumbing work. While โ€œcertificationโ€ may refer to voluntary credentials (like from the International Code Council), licensure is mandatory to work independently.

According to the U.S. Bureau of Labor Statistics (BLS), all states and localities require plumbers to be licensed if they work on residential or commercial systems beyond basic repairs. So when people ask, โ€œHow long does it take to be a certified plumber?โ€ they usually mean: How long until I can get my plumbing license and work legally on my own?


Step-by-Step Timeline: From Beginner to Licensed Plumber

Becoming a licensed plumber typically follows a structured path that blends classroom learning and on-the-job experience. Hereโ€™s the standard U.S. route:

1. High School Diploma or GED (0โ€“1 Year)

Most plumbing programs and unions require a high school diploma or equivalent. If you already have one, you can skip this step. If not, earning a GED takes 2โ€“6 months with consistent study.

2. Enroll in a Plumbing Program or Apprenticeship (0โ€“2 Years)

You have two main entry paths:

  • Trade School/Technical College:
    Programs last 6 months to 2 years and cover plumbing theory, blueprint reading, safety codes, and basic hands-on skills. Tuition ranges from $1,000 to $15,000.
    Pros: Faster start, structured curriculum.
    Cons: Less real-world experience; youโ€™ll still need an apprenticeship for licensure in most states.
  • Union or Non-Union Apprenticeship:
    Sponsored by organizations like UA (United Association) or local contractors, these combine paid on-the-job training with classroom instruction.
    Duration: 4โ€“5 years (standard across most states).
    Pay: Starts at ~50% of a journeymanโ€™s wage and increases yearly.

๐Ÿ’ก Expert Insight:
โ€œApprenticeships are the gold standard,โ€ says Mike Smith, a master plumber with 22 years of experience in Texas. โ€œYou earn while you learn, and employers value that hands-on time.โ€

3. Complete Required Work Hours (4โ€“5 Years)

To qualify for a journeyman license, most states require 4,000โ€“8,000 hours of supervised plumbing workโ€”typically achieved through a 4- to 5-year apprenticeship.

For example:

  • California: 8,000 hours + 720 classroom hours
  • New York: 7,000 hours + 500 classroom hours
  • Texas: 4,000 hours under a master plumber

You can verify your stateโ€™s exact requirements via the U.S. Department of Laborโ€™s apprenticeship database or your stateโ€™s licensing board.

4. Pass the Journeyman Plumbing Exam

Once youโ€™ve logged enough hours, you can sit for your journeyman plumber exam. This test covers:

  • Local and national plumbing codes (IPC or UPC)
  • Math calculations (pipe sizing, pressure, flow rates)
  • Safety protocols
  • System design

Pass rates vary, but thorough prep using study guides or prep courses boosts success. The exam usually takes 3โ€“4 hours and costs $50โ€“$200.

5. Work as a Journeyman (Optional: 1โ€“5+ Years)

After passing, youโ€™re a licensed journeyman plumberโ€”qualified to install, repair, and inspect plumbing systems under general supervision. Many plumbers work at this level for years.

But if you want full independence (e.g., start your own business), youโ€™ll need a master plumber license, which requires:

  • Additional 1โ€“5 years of experience (varies by state)
  • Passing a more advanced exam

State-by-State Variation: Why Location Matters

There is no national plumbing license in the U.S. Each state sets its own rules. For instance:

Florida4 years6,000Yes
Illinois4โ€“5 years8,000Yes
Oregon4 years6,400Yes
PennsylvaniaVaries by city4,000โ€“8,000Yes (local)

๐Ÿ“Œ Pro Tip: Always check your stateโ€™s plumbing licensing board before starting. Some cities (like Chicago or New York City) have additional local requirements.

Can You Speed Up the Process?

While most paths take 4โ€“5 years, there are limited ways to accelerate:

  • Military Training: Veterans with plumbing experience in the armed forces may qualify for credit toward apprenticeship hours.
  • Prior Experience: If youโ€™ve worked as a helper or in a related trade (e.g., HVAC), some states allow partial hour credit.
  • Accelerated Programs: A few technical schools partner with unions to offer โ€œfast-trackโ€ apprenticeships, but these still require the same total hoursโ€”just with more intensive scheduling.

However, beware of โ€œget licensed in 6 monthsโ€ scams. Legitimate plumbing licensure requires verified hands-on experience. Skipping steps risks failing your examโ€”or worse, violating state law.


Pros and Cons of a Plumbing Career

โœ… Pros:

  • High demand: BLS projects 5% job growth (2022โ€“2032)โ€”faster than average.
  • Strong earnings: Median wage is $60,090/year; top 10% earn over $100,000.
  • Job security: Plumbing is recession-resistantโ€”people always need running water and working toilets!
  • Entrepreneurial path: Many plumbers launch successful businesses after earning a master license.

โŒ Cons:

  • Physically demanding: Long hours, heavy lifting, and tight spaces.
  • On-call work: Emergency calls (burst pipes, gas leaks) can happen nights or weekends.
  • Initial pay is modest: Apprentices earn $15โ€“$20/hour; wages rise steadily with experience.

FAQ: Common Questions About Plumbing Certification

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

A: No. A high school diploma or GED is sufficient. Most training happens through apprenticeships or trade schoolsโ€”not universities.

Q2: How much does plumbing school cost?

A: Trade school programs range from $1,000 to $15,000. Apprenticeships are often free or low-cost, and you earn a wage while training.

Q3: Can I get a plumbing license without an apprenticeship?

A: In most states, no. You must complete a state-approved apprenticeship or prove equivalent work hours under a licensed plumber.

Q4: Whatโ€™s the difference between a journeyman and a master plumber?

A: A journeyman can work independently on most plumbing tasks but cannot design systems or pull permits in some states. A master plumber can do all that, supervise others, and run a plumbing business.

Q5: How long does the plumbing exam take?

A: Most journeyman exams last 3โ€“4 hours and include 100โ€“150 multiple-choice questions. Some states add a practical component.

Q6: Are online plumbing courses valid for licensure?

A: Only if theyโ€™re part of a state-approved apprenticeship or program. Standalone online courses do not count toward required work hours.
