I have found that with my auto top off setup, once the PH shuts off, the water continues to flow into my sump. To stop this, I have cut a small hole in the return line near the end to let some air in and added the setup you see in the pic below. Now the water flow is stopped immediately when the PH shuts off . (breaks the syphon I guess).
Here is the initial write up for the auto top off setup.
