Master Plumber Exam 2026 June

The Master Plumber test assesses your ability to plan, install, and supervise complex plumbing systems. While requirements vary by state, most exams cover the International Plumbing Code (IPC) or Uniform Plumbing Code (UPC), encompassing venting, water supply, drainage, and gas piping.

The majority of the Master Plumber exam is code-based. Familiarize yourself with the IPC or UPC index and tables. Speed is crucial in an open-book exam, so know exactly where to find pipe sizing charts and venting rules.
