There are a lot of reasons to love being a plumber. The career is always in demand, thanks to people’s constant need for clean water and reliable plumbing systems. The job is also highly flexible, with opportunities to work in many different industries and at all levels of the field—from apprentice to journeyman to master plumber. And unlike some other trades, you don’t have to spend a fortune to get started: Many community colleges and vocational schools offer affordable training programs, and you can also find apprenticeship opportunities where you’ll be paid while learning the trade.

While a high school diploma is typically the minimum educational requirement to become a plumber, most people who pursue this trade go on to earn an associate’s or bachelor’s degree in plumbing technology, plumbing management, or a related subject. Those who prefer to learn on the job can also find apprenticeships with established plumbing companies. Plumbers also have the option of earning a professional certification to enhance their employment prospects and demonstrate their knowledge of the trade.

The plumbing industry is regulated, so it’s important to find an apprenticeship or job with a company that will provide the necessary on-the-job training and hands-on experience. In most cases, plumbers must also obtain a license to practice their trade. Licensing requirements vary by state, but most jurisdictions require plumbers to pass an exam that tests their knowledge of local plumbing codes and regulations.

Plumbers work with a variety of clients, from home and business owners to construction teams and architects. They must be able to communicate effectively and listen carefully to their clients’ needs and concerns. They also often collaborate with other professionals, including electrical and HVAC contractors, to ensure that all aspects of a building project are coordinated and meet required standards and codes.

Another benefit of working as a plumber is the sense of satisfaction that comes with helping people and making a difference in people’s lives. When you fix a leaky toilet or unclog a drain, people are grateful for your help, and it feels good to know that your work is appreciated.

Plumbers are in demand, and the profession is growing faster than average, according to the U.S. Bureau of Labor Statistics. This is partly because new buildings need plumbing systems, and older homes are in need of upgrades or repairs, and partly because people are focusing on being more environmentally conscious, which means they’re installing low-flush toilets, water flow restrictors, and energy-efficient tankless water heaters.

Being a plumber isn’t for everyone, but if you have the right skillset and enjoy working with your hands, this can be a lucrative and rewarding career. Plumbers can find jobs in all sorts of industries, and there’s room for advancement into supervisory roles or even ownership positions. Plus, there are a lot of great benefits to working as a plumber, from job security and excellent pay to a flexible schedule and the ability to travel.
