Is your pump above or below the top of the water level? If it is above, then it shouldn't back feed. Water will just come up the line to the point that it is at the same height as the pond level.
Do you control when the pump is running and when it isn't? If so, just put a ball valve near your pump and close it when you shut the pump down.
Any physicists on here or just us grease monkeys?
