We have a condensate pump for the furnace that connects via 3/8" tubing and a U-bend into the main sewer line. Been working fine for 20+ years.
We are now getting a new water heater and it requires a condensate drain too. I have a pump for it and will need to also connect the pump output to the sewer drain. Can I simply T using a 3/8" barbed T connector into the same drain ingress that the furnace pumps to?
If not, what is the correct way to drain it?
