iPhone
Pass your journeyman plumber exam on the first try. 1,500+ practice questions filtered by YOUR code — IPC or UPC. The only app that knows the difference.
You know the trade. Let's get you certified.
CertifyIQ is the only plumber exam prep app that lets you filter practice questions by your state's code — IPC or UPC. Texas, Florida, New York, North Carolina? You're on IPC. California, Oregon, Washington, Nevada? UPC. We've got both — with content built on the IPC 2024 and UPC 2024 editions. Check with your local AHJ (Authority Having Jurisdiction) to confirm which edition your state currently enforces.
WHAT'S INSIDE
• 1,500+ practice questions, each tagged IPC or UPC so you study YOUR code
• Mock exams that match the real test format and timing
• Every answer cites the specific code section — learn why, not just what
• Track progress by category: DWV, water supply, fixtures, venting, fuel gas, code regulations
• Bookmark tough questions, drill failed ones
• Study in English, Spanish, or Russian
BUILT FOR HOW YOU ACTUALLY STUDY
Commute? Lunch break? Waiting on an inspection? Squeeze in a few questions whenever you've got a minute. 10 minutes a day adds up fast. Pick up right where you left off.
YOUR CODE. YOUR EXAM. YOUR PACE.
Generic plumbing apps give everyone the same questions. That doesn't help a California plumber preparing for a UPC-based exam. CertifyIQ filters to your code so every question you see is relevant to what you'll actually get on test day.
WHAT WE COVER
• IPC & UPC fundamentals: administration, general regulations, plumbing math
• Fixtures & fittings: faucets, water heaters, fixture requirements
• Drainage & venting: sanitary drainage, indirect waste, vents
• Water supply: distribution, backflow prevention
• Fuel gas: pipe sizing, medical gas systems
