Ok, the plot thickens. Used the blower from the shop vac in all 3 lines, nothing. Oh, in banging on the pipes a little more the cap came off both pvc pipes. The pvc lines seemed to be completely blocked, no airflow. Could not tell on the corrugated pipe, could not get a good seal.
So I decided to add water to the corrugated pipe. Water ran for a minute or two, nothing happening. Not filling up, not going anywhere. So I walked around to the back side of the pool to check for running water. There is a pipe there that functions as a waste drain. That pipe haD a cap, and a wedge cut out for the waste water to flow out, but not collect rainwater. Well, it was wet around the pipe and the cap was broken off.
Now I am on to something. I station a kid by the waste pipe and repeat all the previous actions I did. Air in all pipes, water in the corrugated one. Nothing! So strange.
