You're not as alone as you think, owner of D,D &Clio. Hang in there; you might be able to get your guys legalized by November. I admire your DVM; mine wouldn't vaccinate against rabies for fear of prosecution. Pretty silly laws, I think. Dr. Williams might (maybe?) be able to tell you more about ABS (A-butyl-solide, I think it is). From the plumbing side, it's used for the very reason that it does not decay into the sewage lines, and it's only sensitivity is to UV (sun) light. The stuff's damn near indestructible as long as it's underground. Acids and petroleum products have no effect on it. Supposedly, new ABS pipe is aromatic for a while, but I've never heard of any warnings about it. One would assume there'd be 8 pages of disclaimers if there were a problem. BTW moneybags, ABS pipe is expensive. [Posted in FML issue 1106]
