Trade School
Once you’ve completed high school education or its equivalent, it’s time to enroll in a trade school and take up a plumbing course. Aside from trade schools, you can look for courses at unions, plumbing associations, and community college.
After enrolling, you need to complete a fixed number of hours of training in-class to qualify for a plumbing contractor license. At a plumbing course, the curriculum will include local plumbing codes, water heating system installation, drainage systems, and pipe cutting.
