Plumber Exam Prep: IPC & UPC

You know the trade. Let's get you certified.

CertifyIQ is the only plumber exam prep app that filters practice questions by YOUR code — IPC or UPC. Texas, Florida, New York? You're on IPC. California, Oregon, Washington? You're on UPC. Our questions are built on the IPC 2024 and UPC 2024 editions — check with your local AHJ to confirm the edition your state currently enforces. Every generic plumbing app gives you the same questions. We give you the ones that match your plumber license exam.

THE PLUMBER STUDY GUIDE BUILT AROUND YOUR STATE'S CODE
Whether you're prepping for your plumber license, journeyman plumber certification, or master plumber exam, CertifyIQ gives you the test prep that matches the code your state actually tests.

WHAT'S INCLUDED
• 1,500+ practice questions tagged IPC or UPC so you study YOUR code
• Realistic mock exams in the journeyman plumber test format
• Detailed explanations with code section references — understand the why, not just the answer
• Progress tracking by category, by code, by weak spot
• Bookmark hard questions, drill failed questions
• English, Spanish, and Russian — study in your language

BUILT FOR HOW A PLUMBER ACTUALLY STUDIES
No one's doing marathon study sessions after a 10-hour day on the job. This app works in the margins: commute, lunch break, waiting on an inspection, between service calls. Pick up where you left off. 10 minutes a day adds up fast.

WHAT WE COVER
• IPC & UPC fundamentals: administration, general regulations, plumbing math
• Fixtures & fittings: faucets, water heaters, fixture requirements
• Drainage & venting: sanitary drainage, indirect waste, DWV, vent sizing
• Water supply: distribution, backflow prevention, pressure
• Fuel gas: pipe sizing, medical gas (NITC)

IPC OR UPC — WE KNOW THE DIFFERENCE
Most plumber test prep apps ignore the code split. That's lazy and it costs their users on test day. An IPC question about DWV slope has a different answer than a UPC question. A UPC fixture unit calculation works differently than IPC. Generic apps mix them up. CertifyIQ doesn't. Pick your code in onboarding and every question you see is relevant to your exam.

PLUMBER LICENSE, CERTIFICATION, CAREER
Passing your plumber license exam means more money, more jobs, and more authority. CertifyIQ is a plumber study guide built around the IPC and UPC — so you walk into test day knowing you've drilled the material your state actually tests. Whether it's journeyman plumber certification, master plumber, or a state-specific license exam, your code is what matters.

WHY TRADESPEOPLE CHOOSE CERTIFYIQ
Built by a small team that thinks tradespeople deserve better study tools than the content-farm apps stuffing keywords instead of questions.
