Pat has had sewage flooding for quite some time. The cleanout access is right between the two houses and when the sewer clogs, everything floods the sidewalk until someone sees it. It could be days before anyone goes over there to see it, especially in the winter.
We did a sewer scope inspection and found that the storm water drain was illegally tied into the sanitary sewer, plus the downspout was overflowing, causing the entire area and foundation of the addition to sink into the mud.
This ground movement pushed the sewer pipe down and mud was falling into the pipe.
We were able to locate this spot, excavate and repair the break.
The pipe still has a low spot and some roots, and will need yearly cleaning, but for a 109 year old sewer pipe, that's not bad.
