How to Become a Licensed Plumber in Oklahoma: Step-by-Step Guide

Dreaming of a stable, in-demand career with strong earning potential? Plumbing might be your perfect fit—and in Oklahoma, becoming a licensed plumber opens doors to job security, flexibility, and financial independence. But navigating the licensing process can feel overwhelming. Don’t worry: this guide breaks down how to become a licensed plumber in Oklahoma into simple, actionable steps so you can start your journey with confidence.

What Are the Basic Requirements to Become a Plumber in Oklahoma?

Before you pick up your first pipe wrench, you need to meet Oklahoma’s foundational requirements. The state doesn’t issue a state-wide plumbing license. Instead, plumbing licensing is handled at the municipal level, meaning rules vary slightly depending on the city (e.g., Oklahoma City, Tulsa, or Norman). However, most cities follow similar standards aligned with national codes and best practices.

General prerequisites include:

• Be at least 18 years old
• Hold a high school diploma or GED
• Be legally authorized to work in the U.S.
• Pass a criminal background check (required in most jurisdictions)

💡 Pro Tip: Always check with your local city building department first. For example, Oklahoma City requires apprentice registration , while Tulsa has its own licensing board.

Step 1: Complete a Plumbing Apprenticeship (4–5 Years)

Oklahoma cities typically require 4 to 5 years of hands-on training under a licensed master plumber before you can sit for a journeyman exam.

How to Find an Apprenticeship:

• Join a union program like UA Local 138 (Plumbers & Pipefitters) in Tulsa
• Enroll in a vocational school with an apprenticeship partnership (e.g., Metro Technology Centers or Francis Tuttle Technology Center)
• Apply directly with licensed plumbing contractors

During your apprenticeship, you’ll:

• Work 2,000+ hours per year on real job sites
• Complete 144–200 hours annually of classroom instruction
• Learn about plumbing codes, blueprint reading, safety protocols, and pipe systems (copper, PVC, PEX, etc.)

According to the U.S. Bureau of Labor Statistics, apprentices typically earn 40–50% of a journeyman’s wage initially, with raises every 6–12 months as skills improve.

Step 2: Gain Experience as a Journeyman Plumber

Once you’ve completed your apprenticeship, you can apply to take the Journeyman Plumber Exam in your city.

Typical Journeyman Exam Requirements:

The exam usually covers:

• Drain-waste-vent (DWV) systems
• Water supply and distribution
• Fixtures and appliances
• Local amendments to national codes

You must score 70% or higher to pass. Study guides and prep courses are available through trade schools and local unions.

🔍 Fun Fact: Oklahoma is one of only 4 U.S. states where plumbing licensing is not regulated at the state level—making local compliance critical. (Source: Wikipedia – Plumbing licensing in the United States )

Step 3: Work Toward Master Plumber License (Optional but Recommended)

After working 2+ years as a journeyman, you can pursue a Master Plumber License. This credential allows you to:

• Pull permits independently
• Start your own plumbing business
• Supervise apprentices and journeymen

Master exams are more rigorous and often include business law, advanced system design, and plan review.

How Much Does It Cost to Get Licensed?

Costs vary by city, but here’s a realistic breakdown:

Many employers cover exam fees or tool costs—so ask during your apprenticeship!
