The main difference between a Master Plumber and a Journeyman Plumber lies in their level of certification and responsibilities.

Journeyman Plumbers are licensed to perform plumbing work but typically do not have supervisory authority. Both roles require licensing, but the Master Plumber's qualifications enable higher-level responsibilities and business opportunities.
