Scoped main drain line from toilet There is a pool of sewage water in between both houses (Amanda’s and Nicks house ). Amanda has brand new drain lines in the crawlspace and new clean outs . She has no back ups or leaks that could cause sewage to be pooling on side of house . Nicks house has no clean out nor had an idea of where his sewer line is located so we scoped the line with Camara through a toilet drain . We marked location and of sewer line and found some roots are growing inside but did not find any collapsed areas where sewage could be exiting the line onto the yard . The sewage might be an old capped out line that was filled with sewage that finally collapsed or could be a neighbors line . We will be back to dig up area and locate line
