Overflow Makes flushing sound

Try creating a more direct line to the sump from the hose underneath.
If hose is bent or curled slightly upwards before it flows down to the
sump it could be filling with water until there's enough to to flush.
Also make sure drain in overflow is not slighly plugged with debris

This seems to be a common problem with overflows, sounds like the speed at
which your water is being drained off would be a little too fast
