The Connecticut Plumber Guide

Connecticut regulates plumbing through DCP plumbing and pipefitting licensing. The P-2 unlimited journeyperson plumber can do plumbing and piping work only while employed by a licensed contractor. The P-1 unlimited plumbing contractor can do all plumbing and piping work. DCP says individual applicants must take exams, and Connecticut has no reciprocal agreements with other jurisdictions.

Registered apprenticeship oversight in Connecticut runs through Connecticut Department of Labor Office of Apprenticeship Training (no URL on file).

CTDOL says completed apprenticeship provides a credential and can make the apprentice eligible for occupational licensing exams.
