Condensate drain line installation for minisplit head units when the refrigerant lines come from above the head unit
I’m looking for tips and tricks for condensate drain line installation for head units when the refrigerant lines are run thru the attic above the head units.
The options I’m seeing are:
1) Run condensate lines in PEX to the basement drywells.
2) Tie into the DWV lines with a trap in the condensate line (I don’t like this idea because I am concerned about the trap drying out when the unit isn’t used for a long period and the line becoming a vent)
3) Run outside the building at rim joist height (my concern here is in the winter I may occasionally have drifting snow above the rim joist)
Are there other options? What have other people done?
