Performing thermal imaging scans is recommended when identifying potential leaks in plumbing systems due to its effectiveness in detecting moisture that is not visible through standard inspection methods. Thermal imaging technology uses infrared cameras to visualize temperature variations in walls, ceilings, and floors, allowing for the identification of areas where water may be present. This non-invasive technique helps pinpoint leaks without the need to dismantle or damage existing structures, making it a superior approach compared to merely relying on visual inspections, which can miss hidden leaks behind walls or beneath floors.

Additionally, while uploading footage may be useful for documentation purposes, it does not actively assist in leak detection. Relying solely on visual inspections can overlook subtle signs of leaks, and immediately replacing all piping is both costly and unnecessary without first confirming the existence and location of leaks. Thermal imaging provides a proactive means of identifying trouble spots, which can then be addressed before they lead to more significant issues.
