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.
Plumbers with several years of plumbing experience may earn master status by passing an exam. Some states require a business to employ a master plumber in order to obtain a plumbing contractorâs license.
