Kentucky Journeyman Plumbing Practice Test 2026 – Complete Exam Prep

The essential idea is that inspections require visible, accessible work. If any part is covered before the inspector checks it, it must be uncovered so the inspector can verify that fittings, joints, slopes, trap sizes, venting, and other details meet the code. This ensures the installation is safe, functional, and compliant before it’s concealed behind walls or under fixtures. A permit doesn’t override the need to expose work for inspection, and concealing pieces before inspection would delay approval and could require rework. After the inspector signs off, concealment can proceed where permitted.
