Why lead? Just curious where the lead would come from?


Distilled water (which is basically what condensate is) has an amazing
ability to leach lead from solder joints. I haven't done an analysis of
furnace condensate, but I did one for a coolant system, and the amount
of lead was truly amazing...

If you have a system with lead solder, your condensate could contain
high levels of lead.

Definitely a no no for drinking; for industrial users (i.e. those with
their own discharge permits) may even be a no no for direct discharge.
