How to Become a Plumber (5 Steps)
Becoming a licensed plumber generally takes 4–5 years, depending on your training path and your state’s licensing requirements.
1. Earn a High School Diploma or GED
Basic education in math, science, and technical drawing provides a foundation for plumbing theory and measurements.
2. Apply for a Plumbing Apprenticeship or Trade Program
Most plumbers train through apprenticeships that combine classroom instruction with supervised, hands-on experience. Trade schools can provide pre-apprenticeship training to help you qualify for these programs.
3. Complete Required On-the-Job Training Hours
Apprenticeships typically require 6,000–8,000 hours of supervised work plus technical instruction. Training covers safety, blueprint reading, system installation, and code compliance.
4. Obtain Your State Plumbing License
Most states require plumbers to be licensed before working independently. Licensing usually involves an exam that tests knowledge of plumbing codes, safety procedures, and technical skills.
5. Continue Learning and Consider Specialization
After becoming licensed, plumbers can pursue advanced credentials or specialize in areas such as pipefitting, medical-gas systems, or green plumbing technologies.
Plumbing Licensing by State
Licensing rules vary widely across the country. Most states issue separate credentials for journeyman and master plumbers, while some also regulate gas fitting and pipefitting.
