Journeyman Plumber vs. Master Plumber
There are some key differences between a journeyman licensed plumber and a master plumber contractor:
Licensed Plumber
A journeyman plumber is a licensed professional who has graduated from an apprenticeship and passed a certification exam. Their training typically spans four to five years, and they generally work under the oversight of a master plumber.
Journeyman plumbers are skilled in the installation, repair, and maintenance of plumbing systems in both commercial and residential buildings.
Master Plumber
Master plumbers are experienced contractors who have progressed through the journeyman level, requiring several years of work and the successful completion of an advanced licensing exam. Their training extends beyond the journeyman level by approximately two to five years.
This qualification allows master plumbers to design plumbing systems, obtain permits independently, operate a plumbing business, and supervise journeyman plumbers.

What Test-Takers Are Saying
Don’t just take our word for it! See what real test-takers across the country are saying about the Journeyman plumber exam:
“There’s a few questions about roof drains—when I took my test, they gave us the chart for rainfall and asked maybe 4 questions. Vents are important, as are hanger distances for different materials, trap arm sizes, and fixture unit sizing. It’s helpful to know DFU on all the basic stuff, but they gave us that chart too when I took my test.”

“Wet vents, circuit vents, and minimal sizing were a big pain. I was given a drawing of a two-story residence with a U-shaped drain/sewer system. It was honestly hard to tell which way all the drains ran. I doubt I will ever see a place like that, but you gotta be able to figure it out. I also had questions about plumbing for hospitals and such.”
Reddit User
“In Ohio, there is a test to take for the city you work in to become licensed. The city test is based on the current Ohio Plumbing Code. Definitions, multiple-choice, and pipe sizing were the main things on the test.”

“There will be a water distribution sizing diagram, a drain and vent sizing diagram, rooftop drain sizing diagram, some diagrams about what size wet vents need to be, and roughly 100 code questions that are multiple choice. It is open book and you have plenty of time to look through the code book and find the answer to every question, even if you already know the answer.”
