Monday, late afternoon, Judy discovered the sewer backing up into our basement. Called a plumber, who after 5 p.m. is very expensive. He looked at things and said it is not a plumbing problem but a sewer line problem. We called Roto Rooter. They actually came about 8 p.m. He was able to get our line open again, but couldn't get his snake beyond about 184' and our line is closer to 300' across two neighbors' yards. We dug out a second closer clean-out valve (see picture above) Tuesday, and he returned today with a snaking camera to find out what was wrong inside the line. We found the line has been crushed and only about 2" of space was letting water through. We are going to have to dig down about 5' in one of the neighbor's yards to repair the line, maybe taking out some sidewalk or street to do so. I am expecting a 2-3 thousand dollar expense out of this.
It is good I have a job. This is how you win friends and influence neighbors.
