There was a soft plug at an intersection of waste pipes where the north and south bathroom connect together. I visibly confirm that it was a soft plug with the camera using the baffle inlet at the septic tank to enter the waste system. And then used my sewer snake to punch a hole through the plug and changing the head a couple of times to a larger root cutter bit I was able to chop apart the plug and with the way to the water behind it it washed itself to the tank had them confirm everything is not plugged by running water at every fixture while I watched the piping with the sewer camera.
