route How to become a plumber in New Hampshire
To become a licensed plumber in New Hampshire, individuals must complete a four-year apprenticeship program under the supervision of a licensed master plumber, accumulating 8,000 hours of field experience and 600 hours of schooling. After completing the apprenticeship, applicants can apply for a Journeyman Plumber license, which requires passing the New Hampshire Journeyman Plumber Examination. To advance to a Master Plumber license, an individual must hold a Journeyman license for at least six months and pass the Master Plumber examination. While New Hampshire does not have active reciprocity agreements with all states, it may offer a streamlined path to licensure for those with similar out-of-state requirements, and specific reciprocity is recognized for Journeyman plumbers from many states and Master plumbers from Connecticut, Iowa, and Maryland.
