DJ and I dug up the septic tank last weekend. It is working ok, but I thought I could move the sewer pipe coming out of the house to beneath the foundation in order to put a bathroom in the basement. I was wrong. Although my initial observations into the pipe from inside the house looked promising, there turned out not to be enough slope left in the pipe if it was moved to the underside of the foundation. Drat! This did give me an opportunity to get the tank pumped and now I know a lot more about the system. At least this project is done. Did you ever notice your own septic system smells kinda ok?
