What Is a Master Plumber? A master plumber is a licensed plumbing professional who has passed a state's rigorous testing and certification process for plumbers. To earn this designation, a plumber has to not only pass the tests but accumulate years of practical experience in the plumbing and pipefitting field.
After two to three years of education or apprenticeship, plus another year or two of plumbing experience, you can become a journeyman plumber. After another one to five years of professional plumbing experience, depending on the state, you are eligible to sit for the master plumber exam.
