How to Become a Plumber

Interested in starting a hands-on career in the plumbing trade? You’re in the right place.

Plumbing can be a strong long-term path for people who enjoy problem-solving, working with their hands, and helping homeowners and businesses keep their properties safe and functional. While requirements differ by state (and sometimes by county or city), most plumbers across the U.S. follow a similar route: training → apprenticeship/experience → testing → licensing → ongoing education.

Steps to Become a Plumber in the U.S.

1. Learn your state and local requirements
   • Plumbing rules vary widely. Some areas require licensing for nearly all plumbing work, while others focus heavily on permits and local registration. Start by checking your state’s licensing board and your local building department requirements.
2. Complete plumbing training or a trade program
   • Many new plumbers begin with a trade school, technical college, or a plumbing-focused training program. These typically cover piping systems, fixtures, drainage and venting, water heaters, basic blueprint reading, safety practices, and code fundamentals.
3. Gain hands-on experience through an apprenticeship
   • Real-world experience is the backbone of plumbing. Most people enter the trade as an apprentice or helper and work under experienced plumbers. Many licensing paths require a minimum number of documented hours or years before you can qualify for an exam.
4. Work toward the right license level (if required)
   • Depending on your area, you may progress through levels such as:
   • Apprentice (training + supervised work)
   • Journeyman (tested competency + independent work)
   • Master Plumber / Plumbing Contractor (advanced licensing, often required to operate a business)
5. Build credibility with specialty credentials (optional but valuable)
   • Some plumbers choose extra credentials to stand out or expand services—examples may include backflow prevention, gas piping qualifications, or other local specialty endorsements (requirements vary).
6. Set up your business (if you plan to operate independently)
   • If you’re launching a plumbing company, you may need to form a legal business, register locally, carry liability insurance, and meet bonding/permit requirements depending on your state. Strong operations—scheduling, estimates, invoicing, warranties, and customer communication—can be just as important as the tools in your truck.
7. Stay current with codes and continuing education
   • Many areas require continuing education to renew a license. Even when it’s not required, keeping up with plumbing code updates, safety standards, and new materials helps you stay competitive and professional.
8. Consider joining trade organizations or local associations
   • Professional groups can provide training resources, networking, and industry updates—plus added credibility with customers.
