Home Welcome to NBOPE Helping to serve and protect the health of our community The Nevada Board of Plumbing Examiners was foundedas a nonprofit organization in 2002. Its roots are tied to theMechanical Contractors Association of Las Vegas MCA thePlumbingHeatingCooling Contractors of Nevada PHCCNV and UA Local 525 Joint Apprenticeship Training Committee JATC in Southern Nevada who spearheaded the movement to reclaim and restore integrity to the journeyperson and master plumbing testing and licensing procedures from an outofstate agency. It was their efforts that prompted similar industry and industry trade associations to begin meeting in northern Nevada. And in 2008 in an effort to promote uniformity of skilled licensed and certified journeypersons and master plumbers across the state the plumbing boards from both the north and the south merged forming the NBOPE known today.
