Plumbing and wet rooms
How supply, drainage, waterproofing, appliances and condensate create intermittent or concealed water paths.
Learn the concept, then apply the field method.
The collection alternates between building-science explanation and bounded homeowner observation. It does not turn one clue into a diagnosis.
Supply leak versus drain leak: what it means in a house
Pressurized supply leaks and gravity drain leaks often differ in timing, persistence and relationship to fixture use.

House symptoms often cross systems. Keep competing explanations visible, preserve the baseline and stop where access, electricity, combustion, structure, contamination or hazardous materials create a professional boundary.
