See how plumbing works. Learn the code. Practice solving problems.
Plumbing3D brings residential and commercial building systems, illustrated code lessons and engineering experiments together in one visual learning app. Built for iPhone and iPad, it helps students, apprentices, tradespeople, inspectors and engineers connect the parts of a plumbing system to the principles behind them.
EXPLORE CONNECTED SYSTEMS IN 3D
Explore a two-story home or commercial building. Inspect fixtures, valves, water heaters, pumps, supply piping, drainage and vents. Trace matching system connections in a color-coordinated schematic. Use search, close-up navigation, floor isolation, section cuts, wall transparency and roof controls to investigate the model.
OPERATE FIXTURES AND VALVES
Open fixtures, close branch valves and adjust supply pressure in the Connected Flow Lab. Follow affected supply and drainage paths and compare illustrative flow and residual-pressure readings.
LEARN THROUGH TROUBLESHOOTING
Work through five guided investigations: observe the symptom, choose measurements, diagnose the cause, select a repair and verify the result. Review case evidence, before-and-after measurements, coaching hints and an investigation log. Explore ten fault experiments with animated diagrams, sliders and repair switches.
PRACTICE INSTALLATION INSPECTIONS
Investigate five installation defects in close-up 3D views. Identify the finding, learn the corrective action and compare the repaired condition. Browse additional illustrated violation references.
MAKE CODE REQUIREMENTS VISUAL
Explore six lessons covering drainage slope, trap seals, trap-to-vent distance, backflow protection, fixture flow pressure and cleanout access. Adjust installation conditions, inspect defects and compare bounded IPC/UPC examples. Each lesson identifies its study basis and publisher references. Save your edition, jurisdiction and amendment notes in Code Settings.
EXPERIMENT IN THE ENGINEERING WORKSPACE
Start with home, upper-floor or commercial teaching examples. Adjust flow, inside diameter, length, elevation, pressure and material. Watch a live pressure budget, predict outcomes and compare a saved baseline. Explore drain grade, pump duty and hot-water recirculation with visual diagrams and worked calculations. Save named studies and export calculation steps to PDF.
BUILD AND REVIEW YOUR KNOWLEDGE
Follow beginner, apprentice, inspector or engineering learning paths. Take randomized practice quizzes or a timed 40-question practice exam. Review missed topics, practice glossary flashcards and follow a 13-stop 3D tour. Bookmarks, notes, learning milestones and quiz history are saved on your device.
STUDY TECHNICAL ILLUSTRATIONS
Browse plumbing and mechanical illustrations, including 33 figures from the Mechanical Engineering Visual Handbook. Open a full-screen slideshow, swipe between figures, pinch to zoom and read the accompanying explanations.
Educational models and calculations use stated assumptions. Numeric code exercises identify their verified example editions; selecting another edition does not convert every calculation or reference. Local amendments and manufacturer requirements require separate checking. This app does not provide permit approval, a validated engineering solver or an official certification examination. IPC, UPC and other referenced standards belong to their respective publishers; the app is not affiliated with or endorsed by those organizations.
