need help w/ tunze osmolator

[megs_clark]

I was having the same problem. I just bought mine last month. I had the black tubing just stuck in the water of my sump. I had to raise the tubing out of the water for it to stop overfilling. It was creating a siphon and would pump the water till the alarm would go off and then shut off. As soon as I raised the one end up it stopped. Might be the problem?

hi megs. yeah mine is out of the water. no back siphon. and my top off is below the level.

so today i tried again. set it all up cleaned it etc. i even read the manual *twice*.
so whats happening is that it works but every 10 miniutes the water pump turns on and fills. this goes on until the alarm goes off and it is over filled. must be a faulty sensor or controller?

Could very well be. I have one of the ATO, and mine works great almost from the get-go.
The only problems was due to me, trying to level the sensors (On the magnet), so that it could read correctly. Then I had the filling tube under the sump water level, so it kept back-siphoning until the alarm went on.

After I leveled out the sensors and cinched up the tube to three inches above the water level in my sump, it ran perfectly since.

If you have done all of the about suggestion, and it still malfunctions, I'd return it for another one.
