High humidity vs hidden leak
Widespread surface symptoms differ from one localized active source.
%High indoor humidity
VS≈Hidden plumbing leak
Typical location
Multiple rooms, glazing and cool exterior surfaces
Below bathrooms, kitchens, appliances or supply routes
Timing fingerprint
Overnight, cooking, bathing or limited ventilation
Fixture use or continuous pressurized leakage
Visible or audible pattern
Widespread condensation rather than one local wet spot
Localized active dampness, staining or soft finish
Best separating check
Log relative humidity and compare ventilation conditions
Compare the symptom before and after controlled fixture use
Evidence that weakens it
One isolated unit or weather-entry point
Only appears after rain
The rule
Use this comparison in Clue Engine →Do not repair the resemblance. Verify the pathway.
Color and shape can overlap. Timing, location and a repeatable check usually carry more diagnostic weight.
