I had 8 indoor mitsubishi mini splits installed last year connected to two condensers. Couple different concerns in regards to my condensate lines:
1. Noticed today the plastic tube inside of a line hide was falling out of it. Tech came, pulled it out and as you can see it was duct taped on. I know the connection to the plastic tube was within the line hide and he tested it after by pouring water into the unit and it all came out to the ground. Question is, is it ok for it to drain this way or should I insist on them fixing it (along with the other 4 line hides I have as I’m sure those were duct taped too)?
2. Of my eight units, only one of them seems to have a constant flow of water coming out of it now that it’s hot and humid. Others are an occasional drip if anything. I have seen them all tested and know they drain properly. Is this normal? It’s set to 70 degrees on ac like my other units. This one connects to a different type of tube inside my home before it gets to the exterior whereas all others were installed on an exterior wall. Also does it looks like they used duct tape to connect this one too as you can see in the last picture?
Thanks for your help.

The amount of condensate depends on the indoor humidity
As for connections in the line hides, how should these lines be connected from the water line to the tube from the unit?
> I would not accept a duct tape connection. If your set point is 70 that's a little low, hard on the equipment and it can freeze up. You should be able to get by at 74.

You wouldn't like how I treat my equipment.
I keep my bedrooms at 68 at night.
1. In the last picture in my original post, what is the correct way to connect the pipes?
2. As for connections in the line hides located on the exterior of my home, how should these lines be connected from the flexible water line they are using to the line from the unit?
You can choose to do what you want, but you cannot choose the consequences.
One interior one is from unit to PVC.
All exterior or in foundation connections are unit to the flexible plastic hose.
That tape is pretty hacky. Either is fine in my opinion
I baelieve the cost for a 100 foot roll is very close. +/- $10
All the joints were sealed with PVC glue when the installation was done. While the glue dries, the installation manual recommends wrapping the joints with duct tape. That's why the inside is taped like that as well. That joint most likely never cured.
I think they're full of ..........stuff.

I don't think it can be glued using PVC cement, but maybe someone else here can comment on that.
Maybe that’s what they did with the one pipe out of 8 they did that’s a pvc drain line? This was done more recently, they had other joints to connect for this pipe and know he was using pvc cement. See attached.
