How to Become a Union Plumber: A Step-by-Step Guide

If you're looking for a stable, hands-on career with great pay, benefits, and job security, becoming a union plumber might be the perfect path for you. Union plumbers receive top-tier training, competitive wages, and strong workplace protections. But how do you get started? This step-by-step guide will walk you through the process of joining a plumbing union and building a successful career in the trade.

Step 1: Meet the Basic Requirements

Before applying to a plumbing union apprenticeship, you’ll need to ensure you meet the basic qualifications. These typically include:

Being at least 18 years old
Holding a high school diploma or GED
Having a valid driver’s license
Passing a drug test - the United Association follows federal laws and guidelines on drugs
Being physically capable of performing plumbing tasks

Step 2: Apply for a Union Apprenticeship Program

The most common way to become a union plumber is through an apprenticeship program. Union apprenticeships are typically offered through organizations like the United Association of Plumbers and Pipefitters (UA). To apply:

Find a local union chapter near you (search “UA Local [your city]”).
Complete the application, which may include a written test.
Prepare for an interview process where you’ll be evaluated on your skills, attitude, and willingness to learn.

Step 3: Complete Your Apprenticeship Training

Union apprenticeships typically last 4 to 5 years and include both classroom instruction and on-the-job training. During this time, you will:

Learn plumbing codes, safety regulations, and blueprint reading
Work under experienced journeyperson plumbers
Receive structured pay increases as you gain experience

One of the biggest benefits of a union apprenticeship is earning while you learn—you’ll get paid as you develop your skills.

Step 4: Pass the Journeyperson Exam

After completing your apprenticeship, you’ll need to pass a licensing exam to become a journeyperson plumber. This test usually covers:

Plumbing codes and regulations
Pipefitting techniques
Safety procedures
Practical skills assessment

Once you pass, you’ll officially become a union journeyperson plumber, meaning you can work independently and earn higher wages.

Step 5: Continue Advancing Your Career

Union plumbers have plenty of opportunities for growth. You can:

Specialize in areas like pipefitting, steamfitting, or medical gas systems
Pursue a master plumber’s license to start your own business
Become a foreman or supervisor within your union
Teach or mentor apprentices to give back to the trade
