Re: My HVAC condensate line connects to sewer line

Where I am at, code is condensate to sump, sump to exterior. We had notices that nothing was to go into sewer line but plumbing (septic) line from tub/washer/sink/toilet.

Used to dump outside (condensate ran out wall next to furnace), but that only meant water back at foundation. Ironically, the sump dumps out to shrubs...near foundation.

And that would be fine for summertime A/C condensate but in the winter for a condensating gas furnace, the line would just freeze up and then the sump would overflow.

Seems that a lot of time when these rules are made up, the entire scope is never looked at.
