Had this situation a few times, made a determination that the corrosion started at a section that was field threaded. Another opinion we heard was "poor drainage" as may be evidenced by the pipe that resembles a downspout/roof drain near the corroded conduits. Question please; what type of "tape" was/is evident at the base area of the conduits??
We solve the situation with either PVC or PVC coated GRC if necessary.
