1. Would it hurt anything to have the condensate drain line empty into the washing machine drain that empties into the septic system? I didnt know if the acidic nature of the condensation would have any negative effect on the septic system? The condensate drain currently exits through the basement wall, but come winter I am concerned about it possibly freezing up. (92+ furnace)
2. The line set and condensate drain line exit the basement through a PVC pipe in the cinderblock wall. They used plenty of silicone between the PVC and cinderblock, but where the line set goes through the PVC it is not sealed. Is this left unsealed for a reason? Would it hurt anything if I put a little spray foam insulation in there? Should I just leave it as is?
Thanks for the help.
