We are building the most effective study platform for the Texas Journeyman Plumber exam — combining AI technology with real IPC expertise to help plumbers pass with confidence.
Our mission is simple: help every qualified plumber pass their Journeyman Plumber exam and earn the license their experience deserves. We believe preparing for the journeyman exam should not be a guessing game. Too many candidates walk into the testing center unprepared — not because they lack skills, but because they lack study tools that reflect the true open-book exam experience.
Traditional study materials for plumbing exams are outdated, difficult to navigate, and rarely offer the depth of IPC practice needed to build real confidence. The National Plumbing Code is dense, realistic practice questions are scarce, and its chapter-and-article structure can feel overwhelming without a structured approach. We set out to change that by building a platform that adapts to each candidate's learning pace, identifies weak points, and offers targeted practice where it matters most — from fixture-unit demand and water pipe sizing to drainage slope and vent tables.
At the heart of our mission is a commitment to safety. Every journeyman plumber who pipes a home, a commercial building, or an industrial plant is responsible for the people who will live and work there. By ensuring that license candidates are thoroughly prepared to apply the IPC correctly, we are contributing to safer plumbing installations across Texas and beyond.
PlumberPractice is not a simple flashcard app. It is a specialized, AI-powered study platform engineered from the ground up around the two separately scored parts of the Texas Journeyman Plumber exam: IPC Knowledge (59 questions, 130 minutes) and Calculations (26 questions, 110 minutes), both open-book against the IPC. Every question, every explanation, and every algorithm is designed to reflect the true exam experience at the PSI test center.
Our question bank contains over 7,200 AI-generated, expert-reviewed questions spanning the eight IPC Knowledge study areas and the five Calculations areas. Every question is tagged by IPC article, chapter, topic, difficulty level, and exact code reference — making it easy for candidates to target their weak areas and train their code-navigation speed.
The AI adjusts question difficulty in real time based on your performance. Master a topic and the system challenges you further; struggle and it offers more foundational exercises. This ensures efficient, targeted study sessions.
Timed practice exams replicate the PSI testing environment: separate IPC code navigation and calculations parts with their real question counts and time limits. Build code-navigation speed and confidence before exam day.
Get instant, plain-language explanations of complex IPC requirements. Ask questions naturally and receive exam-focused answers that reference the exact articles and tables.
Detailed analytics show your performance in every IPC chapter and calculation area. Track accuracy by article, monitor difficulty progression, and review your exam history — always know exactly where you stand.
Programmer & AI Specialist — Founder of PlumberPractice
Chuck Onekeo is a programmer and AI specialist with extensive experience building intelligent systems for technical education. Frustrated by the lack of modern, adaptive study tools available to plumbing license candidates, Chuck decided to build the platform he wished he had when preparing for his own technical exams.
Combining his expertise in artificial intelligence, machine learning, and full-stack development, Chuck designed Journeyman Practice from the ground up as an adaptive learning system tailored specifically to the open-book IPC journeyman exam. The platform's AI engine dynamically adjusts question difficulty, generates contextual explanations, and provides personalized study recommendations based on individual performance.
Chuck's vision for PlumberPractice goes beyond helping candidates pass their exams. He believes that well-prepared plumbers complete safer, code-compliant installations, and that technology — especially AI — has the power to dramatically improve how plumbing professionals prepare for high-stakes license exams.
The path to a Texas journeyman license is demanding. Candidates must master the National Plumbing Code across its nine chapters, pass two timed, open-book, code-navigation exams, and develop the tab-flipping speed that makes the difference on exam day. Despite the high stakes, most candidates rely on dense manuals, scattered PDFs, and word-of-mouth advice to prepare.
We saw a gap that technology could fill. The same AI techniques that power recommendation systems, language models, and adaptive tutoring platforms could be applied to plumbing exam preparation — and the result is a study experience that is more effective, more engaging, and more performant than anything currently available to journeyman candidates.
Key problems we set out to solve:
We are committed to building a platform that genuinely helps journeyman candidates succeed. That means:
Every question is reviewed against the IPC. We regularly update our question bank to stay aligned with current code editions and exam bulletins.
We offer a free tier so every candidate can try the platform, plus affordable monthly, yearly, and lifetime plans. No hidden fees, no surprises.
Our success is measured by your success. We continuously improve the platform based on candidate feedback and performance data to maximize pass rates.
We are just getting started. The platform evolves constantly with new features, more questions, and improved AI capabilities. Our long-term vision is to become the go-to study resource for every Texas journeyman plumber candidate — and eventually extend our support to related plumbing license exams across the United States. Whether you are just beginning your IPC Knowledge review or grinding through load calculations, PlumberPractice is built for you.
