Plumbing Programs

Plumbing apprenticeships typically run 4–5 years (8,000–10,000 hours of on-the-job training) combined with 246+ hours of classroom instruction annually, administered through UA Local unions or state-approved programs. Pre-apprenticeship certificate programs can be completed in 1–2 years at vocational schools.

The median annual wage for plumbers is $61,550 according to BLS 2023 data. Master plumbers running their own service business or working on commercial projects can earn $80,000–$120,000. Union plumbers in high-cost-of-living areas like New York City and San Francisco often earn over $100,000 including benefits.

Yes. All states require plumbers to be licensed, but requirements vary. Most states have three tiers: Apprentice, Journeyman, and Master Plumber. The Master Plumber license requires several years of Journeyman experience and a full licensing exam, but allows you to pull permits and run your own plumbing business.

The BLS projects 2% job growth for plumbers through 2033, roughly average for all occupations. However, actual demand is stronger than the headline number suggests: aging water infrastructure, population growth in the Sun Belt, and commercial construction all drive steady work. Retirements in the trade are also creating significant job openings.

Medical gas plumbers (who install oxygen, nitrogen, and other gases in hospitals) and pipefitters working on industrial or power plant projects command the highest wages. Fire suppression system installers (sprinkler fitters) also earn well. Specialty areas require additional certifications beyond standard plumbing licensure.
