So I am about to rebuild my chiller piping due to addition of new tanks, and the local plumbing supply place says that ABS pipe and Propylene glycol do not mix and the glycol will destroy the pipe , also that ABS pipe is not rated for pressure. looking for what is what here and if I will have to run copper as they want me to ( of course they do LOL it costs more)
