The journeyman and master plumber exams in Kentucky are not generic code tests. They lean on KRS Chapter 318 and the Kentucky State Plumbing Code in 815 KAR Chapter 20 — and on a practical portion that national courses barely mention. This bench drills all of it.
Licensing classes, apprentice ratios, permits, inspections, and the administrative rules that live in KRS 318 and 815 KAR 20. A national question bank simply does not have these, and they are free points if you have seen them before.
Isometric riser diagrams, fixture-unit loading, developed length, vent sizing. We drill the sizing tables the same way the exam asks — per 815 KAR 20:120 for water distribution and the DFU tables for drainage.
A caulked lead-and-oakum joint and a copper offset made with 45° ells. The single most common failure is cutting the pieces wrong — so we teach the takeoff method and drill offset multipliers until they are reflex.
A 3-inch horizontal drain line serves a battery of fixtures. Which slope satisfies the minimum grade requirement?
Why: Drain lines 3 inches and smaller require a minimum of ¼ inch per foot of fall. The ⅛-inch minimum applies to larger diameters. Every question in the bank carries this kind of explanation, so a wrong answer teaches you something instead of just costing a point.
Every plan opens the whole plumbing bench. No locked questions.

Both. The bank spans the shared technical ground and the additional law, business, and supervision material the master exam adds. You can drill by category, so if you are only sitting the journeyman you can weight your time accordingly.
Yes, and you should order it early. Our cheat sheets and study guide are aids for memorizing structure and numbers; the adopted code is what governs. Knowing where things live in your own book is worth real points.
The built-in plan runs twelve weeks at roughly three to five hours a week, front-loaded on law and sizing. If your date is closer than that, the plan compresses and the readiness gauge will tell you honestly where you stand.
No. Pour lead and cut copper with your own hands. What we do is make sure your measurements are right — the takeoff math, the offset multipliers, and the sequence — because that is where most people lose the practical.
