Cannot get beyond sewer line
I live in Chicago and we been flooded twice. We do not have sump pump or any other flooding devices. I called a plumbing company they came did the power rod sewer through toilet and could not get pass anywhere. Then they tried the laundry drain and still could not get through to the street sewer. Through the camera they saw standing water, leaves, and branches. So they could not get beyond that point. We have an old gate opening they want to remove the old one and install cleanout on outlet side of sewer check valve. What do you think about that? Their estimate is $3,400(for the check valve and cleanout) and still they are not sure if there are any other problems beyond that point. What should I do? I paid $700 for this cleaning which is not fair in that they did not rod the whole sewer
Thank You
