How To Get Your Plumbing License in CT (Step-by-Step Guide)

Dreaming of launching a plumbing career in Connecticut—or finally going legit after years of hands-on work? You’re not alone. Every year, hundreds of aspiring plumbers search “how to get your plumbing license in CT,” seeking a clear, trustworthy roadmap. Whether you’re a recent apprentice or a seasoned contractor, navigating the state’s licensing process can feel overwhelming. But don’t worry—this guide breaks it all down step by step, with verified details straight from Connecticut’s Department of Consumer Protection (DCP). Let’s get you licensed and earning with confidence.

What Type of Plumbing License Do You Need in Connecticut?

Connecticut offers two main plumbing license types, and choosing the right one depends on your experience and career goals:

1. Journeyman Plumber License
   • Allows you to work under a licensed Master Plumber.
   • Ideal for those with 4+ years of plumbing experience.
2. Master Plumber License
   • Required to run your own plumbing business, pull permits, and supervise journeymen.
   • You must hold a Journeyman license for at least 2 years before applying.

💡 Pro Tip: Most plumbers start as apprentices, become journeymen, then advance to master status. Trying to skip steps usually leads to exam delays or denials.

Step-by-Step: How To Get Your Plumbing License in CT

✅ Step 1: Gain the Required Work Experience

Connecticut mandates hands-on plumbing experience before you can sit for either exam:

• Journeyman License:
  • 4 years (or 8,000 hours) of full-time plumbing work under a Master Plumber.
  • Must include residential AND commercial plumbing projects.
• Master License:
  • Hold a valid Journeyman license for 2+ years (4,000+ hours).
  • Experience must demonstrate leadership, code compliance, and system design.

📌 Note: Military plumbing experience may count! Submit DD-214 forms for DCP review.

✅ Step 2: Complete Required Education (If Applicable)

While Connecticut doesn’t require formal schooling, completing a trade program can:

• Shorten your apprenticeship (up to 1 year of credit)
• Boost your exam readiness

Approved schools include:

• Goodwin University (East Hartford)
• Lincoln Tech (Shelton)
• State-registered apprenticeship programs via the DOL

⚠️ Always verify your program is approved by the Connecticut DCP before enrolling.

✅ Step 3: Submit Your Application to the DCP

Applications are submitted online through the Connecticut eLicensing Portal.

Required Documents:

• Proof of work experience (signed by a Master Plumber or employer)
• $110 application fee (Journeyman) or $135 (Master)
• Copy of government-issued ID
• Affidavit of Experience (Form PLB-APP)

Processing takes 2–4 weeks. You’ll receive an eligibility notice with your exam scheduling link.

✅ Step 4: Pass the Connecticut Plumbing Exam

Both exams are closed-book, multiple-choice, and based on the 2021 Connecticut State Building Code and IPC (International Plumbing Code).

• Journeyman Exam: 80 questions, 4-hour limit, 70% passing score
• Master Exam: 100 questions, 5-hour limit, 70% passing score

Exam Topics Include:

• Drainage & venting systems
• Water supply & distribution
• Backflow prevention
• Local code amendments
• Business & safety regulations (Master only)

📚 Study Resources:

• ICC’s Plumbing Study Guide
• Connecticut Plumbing Code Handbook (available via DCP)
• Practice tests from PSI Exams (the official test provider)

✅ Step 5: Get Your License & Maintain It

Once you pass:

• Your license is issued digitally within 5 business days
• Physical cards arrive by mail in 2–3 weeks

Renewal Requirements:

• Renew every 2 years (odd-numbered years: e.g., 2025, 2027)
• Complete 6 hours of continuing education per cycle
• Pay $130 renewal fee

Failure to renew on time results in late fees ($50) or license lapsing—requiring re-examination.

Common Mistakes to Avoid

1. Incomplete Work Verification
   → Ensure every employer signs your affidavit with exact dates and project types.
2. Studying Outdated Codes
   → CT adopted the 2021 code in 2023. Ignore 2018 or older materials.
3. Missing Continuing Education
   → Track your CE hours early. Approved providers include PPG (Plumbing Promotion Group) and ASSE International.
4. Assuming Reciprocity
   → Connecticut does NOT reciprocate with any other state. All applicants must take CT’s exam.

Frequently Asked Questions (FAQ)

Q1: How long does it take to get a plumbing license in Connecticut?
