Osmolator Nano 3152 Auto Top Off higher than output

[Bob Escher]

has anyone found the Tunze to keep draining into the tank even if it turns off?
My Tunze is 2 feet higher than my sump as I was testing where to place ( at what level) it continued to run I unplugged it not wanting it to keep going. Does it stop water flow when it turns off ( or should turn off?
Thanks

No. Mine is on the floor though.

The reservoir or rather the return tube needs to be 18 inches or higher from the top of the reservoir
If anyone needs to know. I contacted Tunze

Yep, the ATO output has to be above the water line of the reservoir. I too found out just like you did! I ended up using a piece of tubing and making what is essentially a gutter the ATO pumps in to and the drains in to the sump.

You lost me the sump needs to be higher ( or the hose itself) need to be higher than the reservoir

The return line running from your ATO needs to run up so there's no back siphon. I place my RO/DI water on the floor and run the hose up into my display.

Sorry didn't mean to confuse you. Just the output line from the ATO pump needs to be higher than the water line in the reservoir, not the sump itself.

Yeah I can't go that high my sump is only maybe 4 inches higher than the reservoir and that's putting the reservoir on the floor. What do people do with reservoir higher than the sump?

The only real requirement in my opinion is this. The end of the line coming from the ATO pump (so the outlet) has to be higher than the water line/water level of the ATO reservoir. The sump or the sumps location doesn't have anything to do with it.

The challenge becomes finding a way to channel the water to the sump if the output is significantly higher than the sump. That is what I meant earlier about a gutter system of some sort.

Simple diagram I just threw together will show what I'm talking about, at least I hope. In my case I have a small piece of tubing that the output flows in to and then goes down to the sump water line. So my tube is the length of the arrow in my diagram. Otherwise you can hear the water splashing every time the ATO kicks on.

Oh I understand but I need to do something as my ATO reservoir is higher than the sump

I had the same issue when to a 37g ato container. It was taller then my sump. You can run I piece of pvc up the back of the display tank. And put the ato into that.

so the ato line drains into the top of the pvc. Which is about 6 in below the top of tank. Then the pipe drains into my fuge. Problem solved. Works great

The only problem with that ( but thanks for the great idea by the way) is the bottom of my reservoir itself is higher than my stand. I would have to run another pic up the back of the tank turn it 360 to go back down and then into the sump . I guess I'll have to put the reservoir on the floor behind the stand and then run into the stand and then down I think that will work thanks. I was worried when the guy said it has to go up at least 18 inches but that might work too thanks

Ended up running it up to my return where the return splits and then back down
