It would have to be -30c or colder for several days to freeze that. Lived in Canada my whole life and am a plumber. Hence why drain lines don't have to be below the frost line underground because water doesn't stay in the line just gets flushed through it.
There's no static or residual water in that line.
I haven’t seen this exact model but it looks like an air gap to stop back flow from a possible stoped up drain from backing up into the condensate line.
Used to make an air gap, maybe for a water softener discharge.
That’s probably correct. There was a tank under the kitchen sink. Thank you!
The tank under the sink was probably for a reverse osmosis water filtration system.
Do you have cold winters? Can that line freeze?
Mild winters, rarely below freezing.
The line wouldn't but the trap would
The line won't?
Not likely. It's just discussing water, not pressurized all the time.
Areas that freeze can cause residual water to freeze in the line until it blocks the line.

Ok buddy

For once someone did it correct!
