The problem you could run into is the string or small dia. roope cutting into the PVC 90
and stopping you dead in your tracks. I've seen it happen. Most of us have at least seen it happen where the string cuts into a TA and plastic bushing....the same can happen in the elbow on a long run. Solution is to replace PVC 90's w rigid 90's Good luck.
