Thread: Condensate Pump in Attic

Ok, looks like a new addition was done on the house and the secondary drain line previously drained out the back of the house, and I could not find where the primary drained.

However what I ended up finding was A) No Secondary, and B) The primary has a condensate pump that had the drain line which actually pumped upward, (dumb), but the line went back into the condenser, once it entered I could not trace it anymore.


Any ideas as to why it would go into the condenser ?

All of the condensate pumps I see pump "up", mostly because that's why they have to use a pump in the first place (no gravity assist).

I can't clearly see the pic of what you're showing, are you describing the outside termination for the drain line? Where in, or on, the condensing unit is the tube?

I have found that a large number of pumped condensate drain lines do not go where I expect, and they are routed to the closest daylight source they can find, taking whatever path was the simplest at the time of install.
