A free, no-registration practice site for troubleshooting building systems, with explanatory diagrams, quizzes, and fault-finding exercises.
- For

- The 45 fault-finding cases award more stars for solving problems in fewer diagnostic steps; diagrams are simplified for practice.
Field notes
Learners can start with fundamentals, move through illustrated explanations and six-choice checks, then practice tracing faults from a reported symptom. The homepage lists 22 electrical/control-panel cases, 14 water, drainage, and sanitation cases, 6 air-conditioning cases, and 3 electrical-equipment cases. Its operator says published questions are checked by someone with facility-management qualifications; the diagrams are explicitly simplified, and the page cautions that real panel measurements can involve electric-shock risk.
