Thinking about becoming a plumber but unsure how much time it really takes? You’re not alone. Many aspiring tradespeople ask, “How many hours do you need for a plumbing apprenticeship?” The answer isn’t just a number—it’s a journey that blends hands-on work, classroom learning, and real-world problem-solving. Whether you’re 18 or considering a career change at 35, this guide breaks down everything you need to know to get started—and succeed.
What Is a Plumbing Apprenticeship?
A plumbing apprenticeship is a structured training program that combines paid on-the-job experience with classroom instruction. It’s the most common path to becoming a licensed journeyman plumber in the U.S. Unlike traditional college degrees, apprenticeships let you earn while you learn, often with little to no student debt.
According to the U.S. Bureau of Labor Statistics (BLS), most plumbing apprenticeships last 4 to 5 years and require at least 2,000 hours of on-the-job training per year, plus 144–200 hours of technical instruction annually.
How Many Hours Do You Need for a Plumbing Apprenticeship?
The standard requirement across most U.S. states is:
8,000 to 10,000 total hours of on-the-job training
576 to 1,000 hours of classroom or technical instruction
This typically breaks down to:
On-the-Job Training
2,000 hours
8,000–10,000 hours
Classroom Instruction
144–200 hours
576–1,000 hours
💡 Pro Tip: Some states like California and New York may require closer to 10,000 hours, while others like Texas align with the federal standard of 8,000 hours. Always check with your state’s plumbing licensing board.
Does the Hour Requirement Vary by State?
Yes—significantly. While the U.S. Department of Labor’s Office of Apprenticeship sets national guidelines, each state regulates its own plumbing licensing. Here’s how a few states compare:
California
8,000
700+
Must complete through a state-approved program
New York
8,000–10,000
576–1,000
Varies by county
Texas
8,000
576
No state license, but local jurisdictions may require it
Florida
8,000
600
Requires passing state exam after hours are complete
Your hours are logged and verified by your employer or sponsoring organization (often a union like UA or a non-union contractor). Most programs use:
Digital time-tracking systems (e.g., Apprenticeship.gov portal)
Monthly hour reports signed by your supervising plumber
Periodic audits to ensure compliance
⚠️ Warning: Falsifying hours can result in disqualification or even license denial. Always be honest and consistent.
Can You Finish Faster Than 4–5 Years?
In rare cases, yes—but only under specific conditions:
Military veterans may receive credit for relevant experience (up to 1,000 hours in some states).
Trade school graduates with accredited plumbing coursework might reduce classroom hours.
Accelerated programs (e.g., through unions or community colleges) can compress training into 3.5 years if you work full-time year-round.
However, you cannot legally skip the minimum hour requirement. Licensing boards verify every hour before allowing you to sit for the journeyman exam.
What Happens After You Complete the Required Hours?
Once you hit the required hours:
Apply to take your state’s journeyman plumber exam
Pass both written and practical portions
Receive your license (valid in your state or locality)
Work independently or pursue master plumber status (usually after 2–5 more years)
Many apprentices also choose to specialize in areas like commercial plumbing, green plumbing systems, or pipefitting—which may require additional certifications but not necessarily more apprenticeship hours.
Pros and Cons of a Plumbing Apprenticeship
Earn a salary while learning (avg. $18–$25/hr starting)

Takes 4–5 years to become licensed
High job security & demand (BLS projects 2% growth through 2032)
Hours can be irregular (nights, weekends, emergencies)

Despite the challenges, 92% of plumbing apprentices complete their programs, according to the National Center for Construction Education and Research (NCCER).

FAQ: Plumbing Apprenticeship Hours
Q1: Can I count previous plumbing work toward my apprenticeship hours?
A: Only if it was done under a licensed plumber and approved by your apprenticeship sponsor. Self-taught or unverified work usually doesn’t count.
Q2: Do part-time hours count?
A: Yes—but they extend your timeline. If you work 20 hours/week instead of 40, it could take 8–10 years to reach 8,000 hours.
Q3: Are online classes accepted for the classroom requirement?
A: Many states accept accredited online courses, especially post-pandemic. Confirm with your program coordinator.
Q4: What’s the average salary during an apprenticeship?
A: Starting pay is typically 40–50% of a journeyman’s wage. In 2025, that’s about $18–$22/hour, rising to $28–$35/hour by year 4.
Q5: Is there a national plumbing license?
A: No. Plumbing licenses are state or local. However, completing a U.S. DOL-registered apprenticeship makes it easier to get licensed in other states.
Q6: Can I become a plumber without an apprenticeship?
A: In most states, no. An apprenticeship (or equivalent documented training) is required to sit for the licensing exam. Learn more on Wikipedia’s plumbing page .
