Ran camera from 3” roof vent 115’ towards city sewer found one belly in line where build up in the cast iron was the worst but did not see any breaks in the line. Cast iron in bad shape under house and may need replaced or flex shaft remove some of the build up but worried he bottom is week and could break if flex shaft is ran. Clay tile outside of house in good shape all the way to city main. Camera line from roof vent towards city sewer.
