DIY Siphon Overflow and preventing tank overflow

[Fishkeeper101]

Hey guys,
I was planning on installing a siphon driven overflow in my tank that I cant really find a picture of... its got one end of the pvc on the surface of the tank, and then a loop going down to the bottom of the tank, coming back up and over the side, and then down to the sump under the tank.

Okay. You probably have no idea what im talking about, but anywho, heres my question.

I want to install this in my system with my new sump that I'm setting up tomarrow, but heres the thing, if the power goes out, and then comes back on, I need to know that the siphon will start again, as to not overflow the tank, because that would make several parties unhappy in my house (both parents and landlords)....

Anyone have this kind of system, and can attest to its power outage restartingness?

Thanks for any advice.
Aaron.
