bkazmer, my vague recollection is that I read about a fungal infestation in an irrigation system of a huge greenhouse complex, tomato nursery I believe. The expensive mistake was that the operators didn't change the plumbing at the end of ?? years. In this regard has been written about the sickliness (or perhaps better sick-making?) of polyurethane when used for ventilation systems.
Very likely a trifling objection considering the dozen, nay hundreds of various PU-materials.
