My gas furnace and humidifier currently drain via 3/4" pvc into a rinkydink condensate pump that pushes the water to a laundry sink via a 3/8" flexible, plastic tube. The laundry sink drains to a sewage ejector pit, which pumps to septic.
Instead of "double pumping" the condensate, I'd like to drain directly into the sewage basin. The questions are this:
1-Is this permissible? Pretty sure it's ok bkz it's a low volume of water, but just checking.
2-Since the drain will now discharge via a sealed line to the basin, am I required to vent the 3/4" drain from the furnace? The volume of water is so small, I doubt it'll ever self-siphon. The basin is already vented.
Any help appreciated
