ATO question

[Smokey Stover]

Was just trying to help, Once a siphon has started water will seek its own level, Right?
So if the end of the fill hose is below the water level in the resevoir it will continue to flow and you would need some kind of break.
I/my ATO system does not have or need a fitting inline. (still wouldn't trust one not to clog)The end of the hose is higher than the high/full level of the resevoir so siphoning does not continue after pump stops.
However, I re-read the OP and he said it's not a siphon issue. He should check that all his wires are plugged into the correct ports maybe. Then give CoralVue a call.

I'm not going to pretend to completely understand everything about the siphon effect but isn't it safe to assume that since no water is flowing after the pump shuts off that siphoning is not the problem?

Yes.. For the most part if the ATO triggers the pump to turn off and the water stops flowing then a siphon is not the issue..

Unplugged the unit, waited a minute, plugged it back in.
Pump kicked on in a few seconds, topped off to just above safety sensor,
Then pump shut off, water stopped flowing, and alarm began to sound.
I checked the installation and everything is connected properly, without question.
I will email coral vue support I guess
Thanks everyone for your help!
