New Jersey Master Plumbing License New Jersey’s master plumber exam assumes you’ve logged at least 10,000 documented hours in residential and commercial plumbing work. The test covers code-compliant installation methods, blueprint reading, water supply calculations, and drainage design—areas you’ve encountered repeatedly in the field. Without that apprenticeship foundation, you’ll face steep gaps in practical knowledge that classroom cramming can’t close.
