This was an interesting job as we were replacing an existing system that had a number of problems at a home in Roseville, MN.
First, as you can see, the sump was full of rust. But if you look closer you’ll see an illegal drain at the bottom of that sump. Also, the discharge pipe was made of galvanized metal which can rust and corrode. Not only that but the pipe ran straight up from the sump pit in the middle of the room which is pretty inconvenient to finish around; plus, it was noisy.
