The suspected line material is unknown
Use existing installation documents rather than guessing the pipe material. Thermal imaging records surface temperature, not water inside walls.
Unknown material belongs in the test limitations
If installation documents do not identify pipe material, say so rather than guessing from the property or a nearby visible pipe. Acoustic transmission varies with conditions and material, so a proposed method needs to fit what is actually known. Thermal observations remain surface-temperature evidence rather than a view into the line.
Ask what would corroborate a limited result
Clarify which accessible points and additional source evidence the assessment relies on. A weak or unclear observation should not be turned into certainty about an unrecorded buried pipe. The findings should name the material uncertainty and the next authorized information needed before selecting repair access.
What the chosen detection method establishes
Ask how unknown material and access affect the proposed acoustic or temperature investigation. Acoustic findings depend on conditions and need corroborating evidence.
