Abstract
The modern field of Forensic Engineering evaluates the origin, cause, and duration of failed building components. As many failed components are subject to insurance claims and legal probes, a scientific methodology for evaluating such events is inherently valuable. Due to the potential for widespread interior finish damage, failed plumbing supply components are commonly encountered during forensic evaluations. Plumbing pipes themselves and properly soldered fittings rarely fail. Consequently, many failures correspond to mechanical fittings which form connections from pipes to plumbing fixtures. The results of this study provide a scientific methodology to evaluate the duration of connection leaks by quantifying the extent of corrosion, patina, and accumulated deposits on various components by creating and evaluating slow plumbing supply component connection leaks.
Highlights
This paper is arranged by providing a general explanation of plumbing supply and the significance of compression fittings, followed by a corresponding explanation and depiction of the study means and methods

1) Patina and corrosion are accurate indicators of length of time of moisture exposure as colors progressively deepened upon extended water exposure
Summary
This paper is arranged by providing a general explanation of plumbing supply and the significance of compression fittings, followed by a corresponding explanation and depiction of the study means and methods. A basis for color depth analysis is provided, before illustrating the application of color scale compared to actual specimen photos. Color depth data is graphed and plotted against time to provide a visual depiction for analysis. Definitive conclusions are presented, supported by the gathered data
