I have a strange issue. Last year our AC stopped. It was called a clogged drain pain pipe.
The AC tech cut the line and put in a small rubber tube that you can see through.
It happened again this week and I went in and opened the pipe to get the air back on and noticed something strange.
See picture below. There is a slight suction on the pipe that is for drainage in the direction of the arrow. This seems to be causing the water to backup into the pan. Any thoughts on what might be the problem?
