Thinking about turning your interest in pipes, fixtures, and systems into a rewarding career? You’re not alone. With skilled trades in high demand across the U.S., how to become a licensed plumber in CT is a common—and smart—question. Connecticut offers stable job prospects, competitive wages, and clear pathways to licensure. Whether you’re a high school graduate, career changer, or someone already in construction, this guide walks you through every requirement, timeline, and tip to get licensed and thriving in the plumbing industry.
What Does It Take to Become a Licensed Plumber in Connecticut?
Connecticut doesn’t issue a “journeyman” license like many other states. Instead, it has two plumbing license levels:
Apprentice Registration (not a license, but mandatory before hands-on work)
Master Plumber License (the only official plumbing license in CT)
To legally perform plumbing work for pay in Connecticut, you must hold a Master Plumber license—or work under one as a registered apprentice.
💡 Did You Know? According to the U.S. Bureau of Labor Statistics, plumbers in Connecticut earn a median annual wage of $64,820—higher than the national average—thanks to the state’s strict licensing and high demand for skilled trades.
Step 1: Meet Basic Eligibility Requirements
Before you even pick up a pipe wrench, confirm you meet Connecticut’s baseline criteria:
Be at least 17 years old to register as an apprentice
Be at least 18 years old to apply for the Master Plumber exam
Have a high school diploma or GED
Be legally authorized to work in the U.S.
No prior experience is needed to start as an apprentice—but you must register with the Connecticut Department of Consumer Protection (DCP) before beginning on-the-job training.
Connecticut requires all plumbing trainees to officially register as apprentices with the DCP. Here’s how:
Find a licensed Master Plumber willing to supervise you.
Complete the Apprentice Registration Form (available on the DCP website).
Pay the $60 registration fee (as of 2024).
Submit proof of your sponsor’s license and your ID.
✅ Important: You cannot legally work on plumbing systems for compensation without this registration—even if you’re just assisting.
Apprenticeships in CT typically last 5 years, during which you’ll need:
8,000 hours of hands-on field experience
600+ hours of classroom instruction (often through trade schools or unions)
Many apprentices enroll in programs like those offered by Goodwin University or Lincoln Tech, which blend classroom learning with employer partnerships.
Step 3: Complete Required Education & Training
While Connecticut doesn’t mandate a specific school, you must document your training hours. Most successful candidates follow one of these paths:
Union Apprenticeship
Through UA Local 777 (Connecticut’s plumbers union). Paid training + benefits.
5 years
Trade School + Employer
Enroll in a state-approved plumbing program while working under a Master.
2–5 years
Military or Vocational Experience
Some military plumbing roles count toward hours (requires DCP approval).
Varies
Coursework typically covers:
Pipefitting & drainage systems
Connecticut State Building Code (especially Chapter 17 – Plumbing)
Blueprint reading
Safety & OSHA standards
📚 Pro Tip: Study the International Plumbing Code (IPC) and Connecticut Amendments thoroughly—they form the basis of the licensing exam. You can review the code via the International Code Council or your local library.
Step 4: Gain 8,000 Hours of Supervised Experience
You’ll need exactly 8,000 hours (about 4–5 years full-time) working under a Connecticut-licensed Master Plumber.
Breakdown example:
40 hours/week × 50 weeks/year = 2,000 hours/year
4 years = 8,000 hours
Your supervising plumber must verify each hour and sign off on your experience log. Gaps or unverified hours will delay your application.
Step 5: Apply for the Master Plumber Exam
Once you hit 8,000 hours, you can apply to take the Connecticut Master Plumber Exam.
Application Checklist:
Completed DCP application form
Proof of 8,000 supervised hours
$180 exam fee (non-refundable)
Copy of your education/training transcripts
Government-issued ID
Processing takes 2–4 weeks. If approved, you’ll receive an exam eligibility notice with scheduling instructions.
Step 6: Pass the Connecticut Master Plumber Exam
The exam is administered by PSI Services and consists of two parts:
Business & Law (50 questions) – Focuses on CT regulations, contracts, liability, and ethics
Passing score: 70% or higher on both sections
Time limit: 4.5 hours total
Allowed resources: 2021 Connecticut State Building Code book (you must bring your own)
📊 Pass Rate Insight: According to PSI, the average first-time pass rate is 62%. Most who fail underestimate the codebook’s importance. Study tip: Practice open-book tests using real code scenarios.
Step 7: Get Licensed & Maintain Your Credential
After passing the exam:
Pay the $220 initial license fee
Receive your Master Plumber license (valid for 2 years)
Renewal Requirements Every 2 Years:
Complete 2 hours of continuing education in workplace safety (OSHA or DCP-approved)
Pay $220 renewal fee
No disciplinary actions on your record
Failing to renew on time means reapplying as a new candidate—including re-taking the exam!
