WebJan 14, 2014 · Dye testing is a test performed by a plumber. Dye testing determines whether or not your home’s yard drain is connected to a sanitary only sewer. To make this determination, a dye tablet is placed inside outdoor drains, then the drain is flushed with water. If the dye is found in the sanitary drain, then the property will fail the test. There are many types of dye used in penetrant inspections. FPI operations use a dye much more sensitive to smaller flaws than penetrants used in other DPI procedures. This is because of the nature of the fluorescent penetrant that is applied. With its brilliant yellow glow caused by its reaction with ultraviolet radiation, FPI dye sharply contrasts with the dark background. A vivid reference to even minute flaws is easily observed by a skilled inspector.
