(5) A master plumber shall be the master plumber of record for only one plumbing business at any one point in time, and shall not assume or perform the duties or obligations of a master plumber of record for any other plumbing business, without first providing the notice required by this rule.

(6) A master plumber of record shall be responsible for supervising all plumbing work performed by the plumbing business for which the master plumber of record is designated and shall ensure that all plumbing work is done in compliance with all applicable standards, rules, codes, and statutes, including, but not limited to, licensing laws and building codes.
