What the license should say
In Connecticut you'll see one of these on a plumber's card, bid or truck:
- P-1 Unlimited plumbing contractor
- Individual contractor; all plumbing and piping work defined in CGS 20-330 and may hold permits.
- P-2 Unlimited journeyperson plumber
- Individual; all plumbing and piping work only while employed by a licensed contractor.
- P-7 Limited sewer, storm and water contractor
- Individual contractor; water, sewer and storm piping from the utility to just inside the structure.
- P-6 Limited sewer, storm and water journeyperson
- Individual; same scope as P-7 only while employed by a contractor.
- J-1 Limited contractor and J-2 journeyperson (well pumps and water conditioning)
- Individual; domestic water pumps and water conditioning only.
Hiring a company, not a person?
DCP licenses individuals, not companies; the business must have a licensed plumbing contractor (odd-numbered license) who alone can pull permits and sign contracts.
Doing it yourself
Persons doing electrical, plumbing, heating, cooling or sheet metal work in and about a single-family residence they own and occupy are exempt from licensing, subject to inspection and approval by the building official (CGS 20-340(11)).
