Root Rot is just pythium. It is everywhere but healthy plants over come it well. Once your system is infected it must be cleaned to the max. Seems plastics can be etched by nutes and general cleaning. The pythium can become embedded in the plastic as bio-film and you can not get rid of it with out going to extreme meassures. Cheaper to buy new ones and clean pumps in chlorox.
