Plumber Training

If you’ve decided that you want to become a plumber, you’ll need to get the proper training that will prepare you for a rewarding and lucrative career. There may be a number of plumber school options in your area that will allow you to get hands-on training that will make you feel completely confident with your newly learned plumbing expertise. Here is some information about what you can expect to learn–and earn–as you embark upon a new plumbing career.

If you’ve already completed high school and have taken a number of courses that will directly assist you in your plumbing career, like mathematics, you’re likely eligible to become a plumbing apprentice. Most people who decide they want to become plumbers early participate in an apprenticeship shortly after high school graduation; however, you can complete this step toward becoming a plumber at any age. A local plumbing company or union is the best place to search for a professional who wouldn’t mind mentoring you. The apprenticeship allows you to work directly with a professional plumber on a regular basis, so you’ll learn about pipe installation and checking water pressure by helping to perform these tasks. The apprenticeship is often in place of attending a technical school, since you’ve already completed secondary education. However, post-secondary training in addition to being an apprentice may also be required depending on the area you live in.

When you settle on an apprenticeship that is right for you, you’ll need to complete about four years of on-the-job and classroom training in many cases. You’ll need to complete a certain amount of hours in order to get adequate experience.

After starting out as an entry level plumber or better known as an apprentice plumber, you can advance to become a journeyman plumber and later on a master plumber.

Once you become a journeyman plumber you can choose to remain a journeyman plumber or work toward becoming a master plumber.
