During a sewer scope inspection roots were found to be growing into the pipe at the cast to clay transition.
No one could get a camera past this spot to see the total damage.
It turned out that a dead end sewer main is right between the two houses.
Dales house used to be the last one on the street, so at some point in the past the city put a sewer there thinking there was plenty of room off of his property for a sewer main.
Then more houses were built, and this sewer remained, locked between the houses.
We were able to repair Dales root problem and the City main tap at the same time.
