Due to the fact that there is a nationwide shortage of skilled plumbers, becoming one would be considered a very clever choice and you will definitely have many benefits to becoming one.

If you are wondering how you can become a licensed plumber in Connecticut, we are here to help you.

Becoming a licensed plumber in this state requires following specific steps.

There are three levels that you may reach: apprentices, journeypeople, and contractors.

You will need to reach the third level so that you will be licensed to perform plumbing work as an independent contractor.

Connecticut Plumbing License Reciprocity

In the majority of states, there is no reciprocity agreement when plumber licenses are in question, and unfortunately, the same situation is in Connecticut.

If you are already licensed as a plumbing contractor in another state and interested in working in Connecticut,  you will not be allowed to work as a contractor.

The only benefit that you may have is that if you have proof of your work experience, and it is comparable to an apprenticeship, you will not need to enroll as an apprentice before becoming a journeyperson in Connecticut.

Connecticut Plumbing License Requirements

In Connecticut, there are both limited and unlimited contractors.

Which one you can become depends on your eligibility to perform specific tasks, and this can determine which type of plumbing license you can get.

An unlimited contractor is an individual who can do all plumbing and piping work as defined in section 20- 330 of the Connecticut General Statutes, while a limited contractor, on the other hand, is permitted to perform only specific tasks.

To become a licensed contractor in the state, you must work as a licensed journeyperson for at least two years and then complete an exam.

Connecticut Plumbing Journeyman License Requirements

A plumbing journeyperson is an individual who can do all plumbing and piping work but he/she has to be employed by a licensed contractor for such work.

This means that a journeyperson is eligible to perform plumbing work, but not as an independent contractor.

After being a journeyperson for two years, you may qualify to become a full contractor.

In order to qualify to become a journeyperson, you must complete a state-approved apprenticeship program and pass an exam.

The plumbing licensing fees in Connecticut are the following:

  • Plumbing & Piping Limited Contractor – $150
  • Plumbing & Piping Limited Journeyman – $120
  • Plumbing & Piping Unlimited Contractor – $150
  • Plumbing & Piping Unlimited Journeyperson – $120

Plumbing Journeyperson and Contractor Exam

Those of you interested in applying to become journeypeople or contractors should fill out the Occupational Trade License Application found on page 3 of the candidate information bulletin packet, as well as the exam application form found on page 4.

You must include the original copy of your Letter of Apprenticeship Completion Certificate if applying to become a journeyperson or a photocopy of your current license if applying to become a contractor.

A fee is $90 for journeyperson candidates or $150 for contractor candidates.

Journeypeople will have to pay a $65 exam fee, while full-time contractors will be required to pay $130.

Once you have gathered the necessary form, documents, and payment, you can mail the packet to:

PSI Licensure: Certification
3210 East Tropicana
Las Vegas, NV 89121

Upon the review of the submitted documents, you will be able to schedule your exam by calling (800) 733-9267.

It is required that you get at least 70% of the questions correct in order to pass the exam.

On the day of testing,  you must bring two forms of identification — a government-issued ID and a second ID that has your signature and photograph — and any approved reference materials.

Journeyperson Plumbers must pass the P-2 Unlimited Journeyperson Plumber Exam through PSI and they will have to answer the questions related to General Plumbing Regulations, Gas Systems, Cleanouts, Fixtures and Equipment, Water Heaters, Piping, Valves, Controls, etc.

Master Plumbers must pass the P-1 Unlimited Plumber exam and Contractor Business and Law exams through PSI including the questions about Backflow, Traps, and Interceptors, Developed length, Isometric Analysis, Joints, and Connections, Safety and Excavation, etc.

When it comes to Business & Law Exam, questions are related to licensing, Estimating and Bidding, Lien Law, Financial Management, Tax Laws, etc.

Plumbing Apprenticeship Requirements

The required step before becoming a journeyperson is to finish an apprenticeship.

To complete an apprenticeship it takes up to four years and to enroll in an apprenticeship, you must be registered with the Office of Apprenticeship Training.

You and your sponsor should fill out the following forms:

  • Apprentice Registration Agreement;
  • Journeyperson List;
  • Registration/Payment Invoice.

Enrolling will cost $110, and your sponsor should pay $60 of this amount, while you will have to pay the other $50.

This is payable by check or money order to “Department of Labor/Apprenticeship Training.”

Once you have completed the forms and have included the required payment, you can mail the packet to:

Connecticut Department of Labor
Office of Apprenticeship Training
200 Folly Brook Boulevard
Wethersfield, CT 06109

Your enrollment has to be approved and then your sponsor will receive your apprentice identification card.
