The old dickie pipe that runs under our basement has had it. We are having to jet out clogs every day. As a last-ditch measure, we are running a 3 inch line around the perimeter of the basement to where the sewer exits the house. This just needs to last until we are able to run a new line under the basement (or dig outside around the house). We need to make one 90 degree sweep around the corner of the basement with a total drop of around 8 feet to where the connection will be, a total of around 50 feet of line. What do we need to take into consideration when running the line to prevent any messy problems while we replace the "for real" line?
