How to Get a Plumbing License in PA – Step-by-Step Guide

Dreaming of a stable, in-demand career as a plumber in Pennsylvania? You’re not alone—skilled trades like plumbing are growing fast, with the U.S. Bureau of Labor Statistics projecting a 5% job growth for plumbers through 2032. But before you can turn wrenches for pay, you must know how to get a plumbing license in PA. This guide walks you through every requirement, timeline, and tip you need—no guesswork, just clear steps backed by official sources and industry experts.

What Types of Plumbing Licenses Exist in Pennsylvania?

Pennsylvania doesn’t issue a statewide plumbing license. Instead, licensing is handled at the local (county or municipal) level—which means requirements can vary depending on where you plan to work. However, most jurisdictions recognize two main tiers:

1. Journeyman Plumber License
   – For those who’ve completed training and are ready to work independently (but not run a business).
2. Master Plumber License
   – Required to operate your own plumbing business or supervise apprentices/journeymen.

💡 Key Insight: Cities like Philadelphia, Pittsburgh, and Allentown each have their own plumbing boards. Always check with your local authority—but this guide covers the most common statewide pathway.

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

To qualify for a journeyman license in most PA jurisdictions, you must complete a formal apprenticeship. This typically includes:

• 2,000 hours of paid on-the-job training per year (total: 8,000–10,000 hours)
• 144–200 hours of classroom instruction annually (covering codes, safety, blueprint reading, etc.)

Apprenticeships are often sponsored by:

• Unions (e.g., UA Local 157 in Pittsburgh)
• Trade schools (e.g., Pennsylvania College of Technology)
• Private contractors

📌 Pro Tip: Register your apprenticeship with the Pennsylvania Department of Labor & Industry. Though not always mandatory, it adds legitimacy and helps track your hours.

Step 2: Gain Work Experience Under a Licensed Plumber

During your apprenticeship, you’ll work directly under a licensed master plumber. This hands-on experience is non-negotiable. You’ll learn:

• Residential and commercial pipe systems
• Local plumbing codes (based on the International Plumbing Code)
• Drain-waste-vent (DWV) systems
• Water supply & fixture installation

⚠️ Warning: Working without proper supervision can disqualify your hours. Always ensure your mentor is actively licensed in your area.

Step 3: Apply for Your Journeyman Plumbing Exam

Once you’ve completed your apprenticeship, you can apply to take the journeyman plumber exam. Requirements vary by city, but generally include:

You’ll apply through your local plumbing board. For example:

• Philadelphia: Department of Licenses and Inspections
• Pittsburgh: Bureau of Building Inspection

Step 4: Pass the Journeyman Plumbing Exam

The exam tests both technical knowledge and local code compliance. Study resources include:

• International Plumbing Code (IPC)
• Pennsylvania-specific amendments (e.g., frost depth, water hardness rules)
• Practice exams from organizations like PSI or IAPMO

Most candidates spend 4–8 weeks preparing. Don’t underestimate code updates—even small changes can trip you up.

✅ Success Story: In 2023, Allentown reported a 78% first-time pass rate for journeyman candidates who completed a prep course vs. 52% for self-studiers.

Step 5: Apply for Your Journeyman License

After passing the exam, submit your final application. You’ll typically need:

• Exam results
• Proof of completed apprenticeship
• Background check (in some cities)
• License fee ($100–$200)

Once issued, your journeyman license is valid for 2–3 years, depending on your municipality, and requires renewal with continuing education.

How to Upgrade to a Master Plumber License

After working 2–4 years as a journeyman, you can pursue a master plumber license. Steps include:

1. Submit proof of journeyman experience
2. Pass a more advanced master-level exam (often includes business law and complex system design)
3. Pay higher fees ($200–$400)
4. In some areas (e.g., Philadelphia), obtain liability insurance

💼 Why It Matters: Only master plumbers can pull permits, own a plumbing business, or supervise teams in most PA cities.

Common Mistakes to Avoid

Many applicants delay their licensing journey due to avoidable errors:

• Not tracking hours accurately → Use digital logs or a signed journal.
• Ignoring local code differences → Pittsburgh allows different venting than Erie.
• Skipping prep courses → Even experienced plumbers fail due to code nuances.
• Assuming state-wide reciprocity → PA has no reciprocity agreements with other states. Out-of-state plumbers must re-qualify locally.

Cost & Timeline Summary

💰 Total Investment: Most plumbers spend under $1,000 out of pocket—but earn $50,000–$75,000/year once licensed (PA average: $62,300, per BLS 2024 data).
