Master Plumber Exam and Licensure Guide

A master plumber is a highly experienced plumber who possesses advanced installation, maintenance, and repair skills. A master plumber is licensed by the state in which he works, and is subsequently authorized to hold the position of employer or contractor, which grants one the capacity to teach and employ plumbers at the journeyman level.


The main duty of a master plumber is to install, repair, or remodel any size and style of plumbing system. A master plumber’s job requirements are more extensive than that of a journeyman’s, for a master plumber is also responsible for evaluating work orders, coordinating and delegating work orders to employees, and meeting with potential clients to review plumbing problems or needs.
