Sep 9, 2025 | Plumbing

Thinking of diving into plumbing, but not sure where to begin? Whether you’re brand new or building on your skills, plumbing school is a smart first step. Still, terms like “Level 1” and “Level 2” can make things feel a bit murky.

This quick guide clears things up—breaking down both course levels, showing how they fit into your licensing journey, and helping you choose the path that fits your goals.

Why Plumbing Is a Solid Career

Let’s talk about why plumbing is worth considering. Skilled plumbers keep clean water flowing, systems safe, and spaces livable. With aging buildings and constant new construction, their expertise is always in demand. That means steady work and strong career growth for anyone in the field.

How to Pick the Right Plumbing School

Once you’ve decided plumbing’s for you, the next step is finding a solid plumbing license school. Here’s what to look for:

Accreditation

This is key. It means the program meets industry standards and is recognized by employers and licensing boards—so your training holds real value.

Instructor Experience

Great schools hire licensed pros who’ve been in the field. They offer practical insights you won’t get from a textbook.

Facilities and Equipment

Up-to-date labs and tools help you train in real-world scenarios so you’re job-ready from day one.

Job Placement Rates

High placement stats usually mean the school has strong industry ties and career services. Ask how they support you with job searching and apprenticeships.

Course Breakdown: Level 1 vs. Level 2

Aside from picking your school, you’ll need to choose the right course level.

Level 1

Perfect for beginners—the Level 1 plumbing course covers safety, tools, pipework, and how basic systems work in homes. It’s your foundation for moving forward in plumbing.

Level 2

Ready to level up? Level 2 plumbing course dives into advanced systems like drainage, heating, and hot/cold water setups. It includes technical drawings, regulations, and more independent work—prepping you for job sites or apprenticeships.

Which Level Is Right for You?

Start with the Level 1 plumbing course if you’re new—it’s all about the basics and setting up a strong foundation. If you’ve finished Level 1 or have some hands-on experience, go for the Level 2 plumbing course to deepen your skills and take on more complex plumbing tasks.

Enrolling and What Comes Next

To get started, you’ll need to be at least 18 with a high school diploma or GED. Look for trade schools or unions offering programs that mix classroom learning with hands-on training.

After enrolling, the next big step is an apprenticeship—working under a licensed plumber. This usually lasts 2 to 5 years, depending on state rules. Then, you’ll take your state’s journeyman exam to earn your license.

In short: 

  1. Research and enroll in an accredited school 
  2. Choose your course level 
  3. Complete your apprenticeship 
  4. Pass the journeyman exam 
  5. Keep building toward master plumber status

Be sure to check your local plumbing board for specifics.
