Plumbing Program

Journeyman Plumbers

Journeyman Plumbers can install and maintain water and sewer lines, as well as kitchen, bathroom and laundry fixtures and appliances. They may be called upon to do work in residences or businesses, and so must be capable of both small-scale and large-scale work. They must work in the employ of a master plumber or similarly licensed contractor, but can perform many jobs without direct supervision.


An apprentice is a training-level employee who works in the building and construction trades while also attending classes to learn industry skills and safety techniques. Wages for an apprentice increase over the course of this training, which lasts from two to five years depending on the trade. An apprentice who graduates to journey-person is recognized as a well-qualified worker who can command the best wages and benefits.
