Why is my overflow breaking siphon??

[jsodwi]

I just set up a tank and got a pretty decent overflow rated at 1200gph. Company was E-sump. I turn off the pump to make sure it will start up after power outages and it loses siphon every time. The one thing I've noticed was the the u- tubes were not equal it was long on one side and short on another. Any help would be great I don't need any floods and never had this happen before

it always happens to me sometimes for no reason does it make a errrt errt errt sound?

for that type of overflow, the water level on both the inside the tank box and the out side the tank box can never drop below the bottom openings of the "u" pipe. if it does it will break the siphon.

my guess, the water in the out side of the tank box is dropping below the pipe opening because the box is completely draining the sump. can you add any pipe to extend it up so that water stays in the box?

seems like the the tubesare still pulling waterfrom the box even when the pump shuts down. It is draining the overflow box inside the tank till it is much lower than the tank water itself. Isn't there a way to hook up an aqualifter pump or powerhead somehow to stop this from happening? What if I got equal length tubes? would that help?

But when you turn the power back on does it start back up???

no the siphon breaks

I don't have an overflow, but from looking at the designs, the water in the inside tank overflow should end up lower than the tank level on loss of power. It should be at the same level as in the box outside the tank, which is why there is a divider between in the outside box before the drain.

Both ends of the overflow/siphon tube should still be underwater so that when power returns the water in the aquarium overflows into the box and when level is above the level in the outside box the siphon restarts.

A picture is worth a thousand words. Without one, we can only guess what is wrong. There are way too many things that could cause the problem. Post some pics of both sides of the overflow, especially the inside of the outside box. I am going to bet that is where the problem is happening.
