Agreed! Need to place one of your return nozzles closer to the surface so when you lose power and start to siphon back to the sump the siphon gets broken. I have dual overflows and 4 return nozzles....one nozzle is about half an inch below the water and whenever I lose power or do maintenance that shallow nozzle sucks in air and breaks the siphon so I don't get much water back in the sump.

Or use check-valves...but then that cost you some flow.
