The U.S. Bureau of Labor Statistics projects 15% job growth for plumbers through 2032, much faster than average. But to unlock the highest earning potential and run your own business, you’ll need to become a master plumber in PA. This guide walks you through every requirement, timeline, and insider tip to help you succeed—legally, financially, and professionally.
What Does It Mean to Be a Master Plumber in Pennsylvania?
A master plumber in PA is a licensed professional authorized to install, repair, and design plumbing systems for residential, commercial, and industrial properties. Unlike apprentices or journeymen, master plumbers can:
- Pull permits independently
- Supervise other plumbers
- Own and operate a plumbing business
- Design complex plumbing systems
This credential is regulated by the Pennsylvania Department of State, Bureau of Professional and Occupational Affairs (BPOA), and it’s the highest plumbing license tier in the state.
Step-by-Step: How to Become a Master Plumber in PA
Becoming a master plumber in Pennsylvania isn’t instant—it takes time, training, and testing. Here’s the official path:
1. Complete a Plumbing Apprenticeship (4–5 Years)
You must first become a licensed journeyman plumber. That starts with a state-approved apprenticeship, typically lasting 4–5 years. During this time, you’ll:
- Work at least 2,000 hours per year under a licensed master plumber
- Complete 144–200 hours per year of classroom instruction (often through trade schools or unions like UA Local 157)
💡 Tip: Enroll in a program registered with the Pennsylvania Department of Labor & Industry to ensure your hours count toward licensure.
2. Get Your Journeyman Plumber License
After your apprenticeship, apply for the Pennsylvania Journeyman Plumber Exam. Requirements include:
- Proof of 4+ years of experience (8,000+ hours)
- Completed application and $120 fee
- Passing a 100-question exam covering plumbing codes, safety, and math
The exam is based on the 2018 International Plumbing Code (IPC) and Pennsylvania-specific amendments.
📊 Stat: Pennsylvania’s journeyman exam pass rate hovers around 68%—so thorough prep is essential.
3. Gain 2+ Years of Journeyman Experience
To qualify for the master plumber exam, you must work at least 2 additional years (4,000+ hours) as a licensed journeyman. This experience must be:
- Verified by a licensed master plumber or employer
- Focused on diverse plumbing systems (residential, commercial, gas, drainage, etc.)
4. Apply for the Master Plumber Exam
Submit your application to the PA State Board of Plumbers, Heating, Cooling & Refrigeration Examiners. You’ll need:
- Completed application form
- $150 exam fee
- Proof of 6+ years of total plumbing experience (including apprenticeship)
- Copy of your journeyman license
Processing takes 4–6 weeks. Once approved, you’ll schedule your exam through PSI Services, the state’s testing vendor.
5. Pass the Master Plumber Exam
The PA Master Plumber Exam includes:
- 100 multiple-choice questions
- 4-hour time limit
- Topics: IPC code, system design, venting, backflow prevention, gas piping, and PA regulations
You need 70% or higher to pass. Official prep materials are available through the International Code Council (ICC) and local trade schools.
⚠️ Note: Unlike some states, Pennsylvania does not require a business or law exam—just technical plumbing knowledge.
6. Receive Your Master Plumber License
Once you pass, your license arrives by mail within 2–3 weeks. It’s valid for 2 years and must be renewed with 6 hours of continuing education (including 1 hour on PA laws).
