Had a 1 1/4 cable hang up on an obstruction under the street. Any one have any suggestions? We have cut the pipe at the sidewalk and have 2 cables in with obstuction roughly 8' out. We are going to flush line and video inspect. Should we try chipping at the blockage with a smaller auger? We have a small jetter but the blockage did not clear when the snake hung up so I am afraid of making a huge mess in our trench. I also am weary of yanking on it with the mini trac hoe.
