Method
Dye Testing
Colour proves path: following water from a suspected entry to its exit.
Dye introduced at a suspect fixture, drain or detail appears where the water goes, confirming connections and entry paths that are otherwise invisible.
How it works
- Dye placed at the suspect source
- Observation at downstream or interior points
- Photographic documentation of the result
Limits, stated plainly
- Works only where a fast path exists
- May require repetition under different conditions
- Often paired with flood or spray testing

Quick answers
Is Dye Testing invasive?
No. The method works from surfaces and accessible points; if a small access point is needed to confirm a finding, it is discussed before anything is opened.
Can Dye Testing be used on its own?
Dye Testing is strongest when paired with a confirming method. Findings are only reported once verified, which is why single-method clues are labelled as such.
