In Philadelphia, Pennsylvania, requirements include completing an apprenticeship and passing an examination, while in Maryland, you'll need at least four years as an apprentice, 7,500 hours of training, and passing a written exam for a journeyman license56. Licenses ensure compliance with local regulations and safety standards, with opportunities for advancement to a master plumber role after additional experience.
