Cade gravity fed ato

[shadyraro]

Can the cade gravity fed ato back siphon? The water level in mine has risen overnight but I don't understand how this is possible, I'm confused...

As the water reservoir is at the top of the tank and feeds down into the sump, I cannot see how this would back siphon.

I agree. I think it is coming from the return pipe that runs inside the ato reservoir, so I’ll have to check it when I get home.

I had a weird siphon event, I had this tube and I connected it to a pump, when the float shut off it urned off the water but water in the tube allowed the water to siphon, it is hard to explain but it happened to me.

I drained the ato and removed the return pipe, and I'm glad I did because there was no gasket on the underside of the bulkhead :astonished-face: Anyway it's never leaked there thankfully and that wasn't the problem, the issue was the gasket at the return nozzle end wasn't seated properly so it had started seeping saltwater into the ato. I reset everything and it's fixed the problem, I contacted Cade and they're sending me 2 new bulkhead gaskets and a return gasket for free. Thanks Cade!

I am glad you figured it out.
