Drain keeps backing up between to manholes since we moved in, every 3 months or so ,when I rod it I feel no resistance and it clears I just put my head down furthest away manhole looking back I can see what looks like a large piece of concrete.
It must be tapered and the end I rod to feel no resistance but other end looks square edge.
Any ideals how to even open up the diameter of the pipe a bit more (acid ect) I can get a bar onto the concrete but it is solid and don't wont to hit to hard as the pipe is clay.
Or as I think have to dig it up.
Thank you
