How to Become a Plumber in 5 Simple Steps


What is a Plumber

Before we start breaking down into simple steps what you need to do, and how to become a plumber let’s see what a plumber is and find out if you are made for this work.

As a plumber you will not only install new faucets and unclog drains. You will be working in commercial and residential areas, water treatment facilities, power plants, factories and water disposal plants maintaining, installing and fixing all kinds of pipeline systems.

While the job duties vary depending on the project you work at and the specialty you have chosen there are certain duties you can expect to perform as a plumber:

  • Installing piping systems
  • Maintaining piping systems
  • Fixing piping systems
  • Working with plumbing tools
  • Reading and follow blueprints
  • Designing piping systems
  • Understanding what materials they need to use and why
  • Performing basic carpentry
  • Attaching and weld fillings
  • Installing fixtures (toilets, showers, bathtubs)

Plumbing Specialties


Pipelayers install and set piping for different plumbing systems, like storm drains and water mains. If you decide to take this specialization you are expected to grade and dig the trenches where you will install the pipes, install them and attach them together by gluing, welding, or cementing.

Pipefitters and Steamfitters

As a pipefitter you will get mostly involved in huge industrial projects. You will install electricity generation systems, cooling and heating piping systems and maintain them. As a steamfitter you will specialize and work in high pressure piping systems that move liquids and gases like compressed air steam or water.

The average salary of a plumber is $50,660

Becoming a Plumber

Step 1: High School Preparation

Plumber High School Courses

Your first job to become a plumber is to finish high school. All plumber schools require a high school diploma or GED.

You also need to get good grades at certain classes, as employers who are looking for apprenticeship candidates request ACT scores.

Math classes

As a plumber you will have to take measurements and make complicated calculations daily, so taking good grades at courses like algebra and calculus will not only help you get accepted at a school and find an apprenticeship but also will make your daily routine as a plumber easier. It is also a good idea to take geometry classes as it will be a very useful knowledge to have when installing pipes.

Science classes

Another great class to attend and get good grades is physics, especially if you are planning to follow the pipefitting and steamfitting route, because you will be working with high pressure and electrical generation systems.

Computer classes

If you want to advance your plumbing career a good idea is to get Engineering Design/CAD classes. They will help you get accustomed to computer based programs that you will use when you will design a piping system.

Step 2: Get Plumbing Training

Step 3: Complete a Plumbing Apprenticeship program

This is probably the most important step as you will gain valuable experience while getting paid.

Apprenticeships are 5 year programs mostly run by local plumbers unions.

You will get on the job training under the supervision of a journeyman or a master plumber and also attend classes where you will learn the theory behind plumbing.

If you get accepted to an apprenticeship you will need to fill in 1,700 – 2,000 hours on the job training and at least 246 hours of theoretical classes.

In order to get accepted at a plumber’s union apprenticeship you will need:

  • To be 18 Years old (16 at some programs)
  • A Valid Driver’s License
  • High School Graduate or GED Equivalent Certification
  • Provide Reliable Transportation
  • Social Security Card
  • Physically Able To Perform Daily Plumbing Tasks
  • Take an Aptitude Test
  • Personal Interview
  • Take and Pass a Drug Test

It is a great idea to attend an apprenticeship as you will get paid while getting on the job training under an experienced plumber.

You will also get the theoretical knowledge required to become a great plumber.

If you cannot get accepted for an apprenticeship at your local union you can always contact a local master plumber that has his own business and ask him if he can take you on as an apprentice.

Step 4: Get your plumbing license

The standards for getting licensed vary from state to state but having a 2 to 5 years of working experience along with passing a written exam of the local codes and plumbing trades will get you licensed.

Step 5: Get additional certification (Optional)
