Thinking about becoming a plumber—but unsure if the paycheck during training is worth it? You’re not alone. Many aspiring tradespeople ask, “How much does an apprentice in the plumber’s union make?” The good news? Union plumbing apprentices earn while they learn—and often start with solid pay that grows fast. In this guide, we’ll break down real numbers, regional differences, and what you can expect from day one through journeyman status.
What Is a Plumber’s Union Apprentice?
A plumber’s union apprentice is someone enrolled in a formal, paid training program—typically run by a local chapter of the United Association (UA) of Plumbers and Pipefitters. These programs blend on-the-job training with classroom instruction, usually lasting 4 to 5 years. Unlike non-union paths, union apprentices benefit from structured wage progression, health insurance, pension plans, and nationally recognized credentials.
According to the U.S. Bureau of Labor Statistics (BLS), plumbing is a high-demand trade with projected job growth of 5% from 2024 to 2034—faster than average. And union apprenticeships are often the gold standard for entry.

How Much Does a Plumber’s Union Apprentice Make in 2026?
Apprentice wages aren’t fixed—they increase every 6 to 12 months as you gain skills and complete training hours. Most unions follow a percentage-of-journeyman scale. Here’s a typical progression:
| Year of Apprenticeship | % of Journeyman Wage | Avg. Hourly Wage (U.S.) | Annual Earnings (Full-Time) |
|---|---|---|---|
| Year 1 | 50% | $18–$22 | $37,000–$46,000 |
| Year 2 | 55–60% | $20–$25 | $42,000–$52,000 |
| Year 3 | 65–70% | $24–$29 | $50,000–$60,000 |
| Year 4 | 75–80% | $28–$34 | $58,000–$71,000 |
| Year 5 (if applicable) | 85–90% | $32–$38 | $66,000–$79,000 |
Note: Journeyman plumbers in union roles average $35–$45/hour in 2026, depending on location.
Regional Differences Matter
- New York City: First-year apprentices often start at $22/hour + full benefits.
- Texas (non-union-heavy areas): May begin closer to $16/hour, but union locals like UA Local 68 in Dallas offer $19+/hour.
- California: High cost of living = higher wages. UA Local 434 (San Diego) pays $21.50/hour in Year 1.
Always check your local union hall’s wage sheet—they’re publicly available and updated annually.
What Benefits Do Union Plumbing Apprentices Receive?
It’s not just about hourly pay. Union apprentices typically get:
✅ Health insurance (medical, dental, vision) — often starting in Year 1
✅ Pension & retirement plans (e.g., UA’s multi-employer pension fund)
✅ Paid vacation & holidays
✅ No student debt — training is free or low-cost (unlike trade schools that charge $10k–$20k)
✅ Job placement assistance upon completion
Compare that to non-union apprentices, who may receive no benefits and inconsistent pay.
How to Become a Union Plumbing Apprentice (Step-by-Step)
Want to start earning while you train? Here’s how:
- Meet Basic Requirements
- Be at least 18 years old
- Have a high school diploma or GED
- Pass a basic math and reading test (often includes fractions, measurements, and blueprint reading)
- Find Your Local UA Chapter
Visit ua.org and use their “Find a Local” tool. Each local sets its own application dates—most accept applicants once or twice a year. - Submit Application & Take Aptitude Test
Prepare for a 2-hour exam covering algebra, geometry, and mechanical reasoning. Free practice tests are often available through the local union. - Attend Interview
A panel scores you on communication, work ethic, and motivation. Dress professionally—even for a trade interview! - Get Accepted & Start Training
Once in, you’ll work 40+ hours/week on job sites and attend classroom sessions 1–2 nights/week. You’ll track your hours via the union’s system.
⏱️ Tip: Apply early! Some locals have 200+ applicants for 20 spots. Volunteering or taking a pre-apprenticeship course (like those at community colleges) can boost your chances.
Union vs. Non-Union Plumbing Apprenticeship: Key Differences
| Factor | Union Apprenticeship | Non-Union Apprenticeship |
|---|---|---|
| Pay Structure | Fixed % increases, transparent | Varies by employer; often lower |
| Benefits | Full health, pension, vacation | Rarely offered |
| Training Quality | Standardized, accredited | Depends on employer |
| Job Security | Strong (collective bargaining) | At-will employment |
| Long-Term Earnings | Higher ceiling ($80k–$120k+) | Often capped below $70k |
If long-term stability and benefits matter, union is almost always the better path.
