Upon arrival to the home and the homeowner made me aware that they have had the septic tank pumped out two months ago but the house was still backed up. Upon further diagnosis I came to the conclusion that there was indeed a whole home stoppage however I found that there was a break underneath the home as well as some large bellies in the line that I believed to be the cause of the blockage. At this time we are sending one of our drain specialist out to look at the line and see what needs to be done to get this issue resolved.
