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.
However, in most states, an individual interested in becoming a licensed or certified master plumber must take and pass the master plumber exam administered by the state in which he or she wishes to work and have at least the amount of experience working as an journeyman plumber set by the state.
