Me too, but the reason I have it on my mind is because I was reading the technical manual [1] for the fancy new NG boiler I'm having installed next week, and they specifically list the max concentrations of lead, chromium, cadmium, and other scary things in the condensate water after the neutralizing unit, with a recommendation to check with your my regulations to ensure that it's legal to dispose of this water down the drain. Possibly it's just an abundance-of-caution thing, but I assume the reason for the warning is that in some places it isn't, perhaps because of stricter environmental standards, or maybe a sewage treatment system which isn't set up for this. 1: https://www.viessmann.ca/content/dam/vi-brands/CA/pdfs/wall-mount/vitodens_100_tdm.pdf/_jcr_content/renditions/original.media_file.inline.file/vitodens_100_tdm.pdf https://www.viessmann.ca/content/dam/vi-brands/CA/pdfs/wall-...
