I have an existing sewer manhole that has a drop between the inflow and outflow. I cannot figure out how to assign the measured elevations to the inflow invert. None of the various elevation options retain the value that I assign to it. I have no clue as to where the inflow invert elevation is coming from in the attached screen capture, but when I change it's value it always resets to the value shown.
How can I model this?
