I have tried the hand held snake and didn't get anywhere. Couldn't tell if I was at a bend or a blockage.
The runs of pipe are about 15 feet. I believe it is the flex pvc and the pool is about 30 years old. I have been here for 10.
While blowing out the lines or forcing water through -- There was something getting through. But when I turned on the filter there was almost no suction. Little pieces of plastic where coming out and pine needles.

If the pipes are collapsed or blocked -- will have to dig up the concrete to lay new pipes?
