Upon arrival rank sink for several minutes and pulled up the floor drain. Flushed toilet 6+ times and saw no movement in the floor drain and no bubbling or backing up in the toilet. Noted that there was waste in the floor drain, which is an indication of the backup that occurred the previous day. Poured water down the floor drain and confirmed flow. Ran more water and flushed the toilet more and all water is draining properly. Gave customer option for camera inspection. Customer declined at this time.
