What Do I Need to Become a Plumber? (Step-by-Step Guide)

Thinking about a hands-on, in-demand career that pays well and offers job security? You’re not alone. Many Americans are turning to skilled trades like plumbing—especially as the U.S. faces a growing shortage of qualified tradespeople. If you’ve ever asked yourself, “What do I need to become a plumber?”, you’re in the right place. This guide breaks down everything: from education and licensing to tools and earning potential—so you can start your journey with confidence.

What Exactly Does a Plumber Do?

Before diving into requirements, it helps to understand the role. Plumbers install, repair, and maintain pipes, fixtures, and systems that carry water, gas, and waste in residential, commercial, and industrial settings.

According to the U.S. Bureau of Labor Statistics (BLS), employment of plumbers is projected to grow 2% from 2022 to 2032, with about 48,000 openings each year—mostly due to retirements and industry demand.

Plumbers don’t just fix leaky faucets. They:

• Read blueprints and building codes
• Install water heaters, sewage systems, and gas lines
• Diagnose pipe blockages using video inspection tools
• Ensure compliance with local and federal safety regulations

This variety makes plumbing a dynamic, problem-solving career—not just a “fix-it” job.

Step 1: Meet Basic Eligibility Requirements

To start your plumbing journey, you’ll need:

• A high school diploma or GED
• Be at least 18 years old (in most states)
• Pass a background check (required by many apprenticeship programs)
• Have a valid driver’s license (you’ll travel between job sites)

Strong math, mechanical aptitude, and communication skills are also valuable. You don’t need a college degree—but you do need commitment and attention to detail.

Step 2: Complete a Plumbing Apprenticeship

This is the most common and recommended path into the trade. Apprenticeships combine paid on-the-job training with classroom instruction—typically lasting 4 to 5 years.

How to Find an Apprenticeship:

• Join a union program (like UA—United Association of Journeymen and Apprentices of the Plumbing and Pipe Fitting Industry)
• Enroll through a non-union contractor or trade school
• Apply via your state’s Department of Labor or workforce agency

During your apprenticeship, you’ll log 1,700–2,000 hours of hands-on work and 200+ hours of classroom learning per year. Topics include:

• Pipefitting and soldering
• Drain-waste-vent (DWV) systems
• Local plumbing codes (based on the International Plumbing Code)
• Safety protocols (OSHA compliance)

💡 Pro Tip: Many apprentices earn $15–$20/hour starting out, with wages increasing as skills improve. By journeyman level, pay often exceeds $30/hour.

Step 3: Get Licensed (It’s Required in Most States)

Almost every U.S. state requires plumbers to be licensed—but rules vary. Generally, you’ll need to:

1. Complete your apprenticeship
2. Pass a state or local licensing exam (covers code knowledge, math, and safety)
3. Pay a licensing fee ($50–$300, depending on location)

Some states (like Kansas and Missouri) have no statewide license, but cities may require local certification. Others (like California and New York) have strict tiered systems:

• Apprentice → Journeyman → Master Plumber

📊 Stat Alert: Master plumbers in Alaska earn a median wage of $95,000/year, while those in Mississippi average $52,000 (BLS, 2023). Location matters!

You can verify your state’s requirements through the National Inspection Testing and Certification Corporation (NICET) or your state’s contractor licensing board.

Step 4: Gather Essential Tools and Gear

You won’t need a $10,000 toolkit on day one—but you will need basics. Most apprentices start with:

Over time, you’ll add a drain camera, pipe threader, and pressure testing kit. Many employers provide heavy-duty tools—but having your own shows professionalism.

Step 5: Consider Specialization (Optional but Profitable)

Once licensed, you can specialize to boost income and job opportunities:

• Residential plumbing: Homes and apartments (most common entry point)
• Commercial plumbing: Offices, schools, hospitals (higher complexity)
• Service & repair: Emergency calls, leak detection (great for entrepreneurs)
• Green plumbing: Installing water-efficient fixtures and solar water heaters

Specialists in medical gas piping or fire suppression systems often earn 20–30% more than general plumbers due to certification requirements.
