Upon arrival I went back to the master bathroom shower where there are 2 floor drains. I had the camera on the left drain to see and make sure that my sewer machine was going in the right direction. Once the sewer machine made the correct turn I was only able to get approximately 1 foot before the cable started to bind up. There is something hard and obstructing the drain. When I pulled the cable out the tip was polished. At that time I ran water and the drain immediately backed up and is not draining. I’m unable to get the camera down the drain past a certain point due to the diameter of the drain line.
