Called them on Friday afternoon around 3:30pm. Promised someone to be at my home by 9-10am next day and sure enough a van was at my home at 9:05am! They ran a camera through my sanitary line outside to check for cracks or leaks, none found thankfully! Anyhow they ran the camera through all underground sanitary lines not once, not twice, but 4 times! Made sure I watched with them to make sure I was satisfied! Explained each thing they saw along the way. Outstanding and highly recommended!
