Pulled hallway toilet to and ran camera down drain. While performing camera inspection I found several root intrusions in customers backyard under patio. Was unable to get past last root intrusion. Recommend performing repairs to sewer main and installation of mainline cleanout. Explained to customer while sewer line is opened and roots are removed we can then perform further camera inspection of the line to make sure there are no further issues Performed spot repair in back patio. Found that the root intrusions were coming through the clay pipe, as well as a previous repair that had been performed. After performing repair we found that customer existing cast iron drain leading back towards the house was in very poor condition with several fractures, breaks and root intrusions through out the line. Strongly recommended to Cutsomer to perform epoxylining to avoid future issues. Also found that customer is in deed on septic tank and not connected to city sewer as originally stated.
