I assume that you're referring to darkroom plumbing... I haven't read
anything about this recently, but my understanding from years ago is that
B&W chemistry is ok, color negatives kind of ok if cleaned up by a thorough
fresh water wash, positive processes work a few years & need plumbing
replacement (ciba/ilfo chromes don't work at all). I don't recall anything
about alternate process chemistries. Hopefully, you'll be able to get some
more recent info.

Subject: Photo chemistry destroying PVC
Has anyone heard of photochemistry destroying PVC? I've received an email
stating that this is occurring. We use both black and white and color
chemistry.
Direct emails are appreciated since I digest this list.
Thanks,
Kim
