To become licensed as a plumber, at least four years of experience as an apprentice plumber supervised by a master plumber is necessary. You also must pass both journeyman and master plumber exams administered by PSI; PSI works directly with the State Board to help with these examinations, and their tests cover topics like plumbing safety, materials, traps, fixtures and appliances supply systems backflow prevention, waste systems plumbing mathematics along with plumbing mathematics for master plumber exams whereas for journeymen plumber exams there will only be 75 questions covering similar subjects on journeyman exams.

Instead, its State Board of Plumbers evaluates every applicant individually by considering factors like your criminal history and crime type as well as the time that has elapsed since any offense took place.

Licensed plumbers have the skills and qualifications needed to build and repair pipes, install fixtures, inspect for code violations in residential dwellings, and advertise their services legally while also legally advertising, obtaining commercial insurance, and bidding on government contracts. In an emergency, they can even make service calls to perform emergency repairs.

In certain instances, they may waive background check requirements altogether.

Plumbing Journeyman License

Once granted this license, journey plumbers can work under direct supervision from either a master or limited master plumber holder until passing their backflow prevention device test training and passing their written exam before being eligible to apply for master plumber licensing – with an additional 32 hours of backflow prevention device test training and written exams before moving up the licensing ladder toward master plumber licensing as an ultimate goal!

The State Board of Maryland partners with PSI, an outside testing company, to administer its plumbing licensing exams. To take part in one, all supporting documents related to employment history and education/training, as well as payment of the $65 exam fee, must be sent directly to PSI for processing, in addition to in-person and online exams offered by PSI and State Board of Maryland, respectively.

Assuming you have a master or journey plumber overseeing and accepting liability should anything go wrong, working as a plumber in Maryland without a license is possible; however, the State Board of Maryland does not recognize permits from other states; Delaware remains reciprocal for licensing purposes only.
