Before I invested a lot of money in my lower level with all its new plumbing, I wanted to make sure that the waste line was reliably connected to the municipal sewer. I had replaced some of the sewer main the previous winter and was pretty sure that there was a lot more bad terracotta pipe between the house and the main sewer line. Sure enough, I had the plumber snake the video camera down the line and he declared that the terracotta was basically gone (100+ years old) and that my sewer line was really just a tunnel through the dirt.

Replacing a sewer main is not that big a deal normally. It involves a backhoe, two guys, two days, and a check for $10-15 thousand. You have to reseed your lawn too. Except nothing is normal about my house. Turns out that my sewer main runs 200+ feet down the block under my neighbors sidewalk to the sewer line on the next street down the hill. The plumber said that replacing it would be $20-25k for his part, plus $15k or so to replace the half block of sidewalk and curb that would have to be removed.
