and the water doesn't really run uphill, the opening at the pump is
lower then the opening at the far end so the water runs uphill pat of
the way but then runs down hill at the pump more then it went uphill.
There is a net downhill for the water.

Thats another solution for you, if you can get the opening at the far
end of the pipe to be lower then the opening at the pump, the water
will continue to run out all by itself when the pump shuts off.
