The board shall establish three separate license categories and two endorsement categories, described as follows:

1. (1) Master plumber--A license that entitles the individual to enter into contracts or agreements and to secure permits to perform plumbing work and assigns the individual responsibility for plumbing that occurs under such contracts or agreements, or under his or her supervision. A master plumber who uses unlicensed individuals to do plumbing work that only a licensee is permitted to do abuses the master plumber license and becomes subject to disciplinary action by the board.
2. (2) Journeyman plumber--A license that entitles the individual to do plumbing work only under the general supervision of master plumbers and only under contracts or agreements to perform plumbing work secured by them.
3. (3) Medical gas piping technician--An endorsement in addition to a journeyman or master plumbing license entitling the individual to install pipe, systems, and equipment used solely to transport gases used for medical purposes.
4. (4) Plumbing Inspector--A license that entitles the individual to do plumbing inspections as an employee of a political subdivision, or if approved by the board, as an agent of a political subdivision.
5. (5) Water supply protection specialist--An endorsement in addition to a journeyman or master plumbing license certifying the individual has been deemed by the board to be competent in the inspection of the plumbing work or installation of a public water system distribution facility or of customer-owned plumbing connected to that system's water distribution lines.
