need ato advice

[Authentic]

I have a tunze ATO connected to a tall large rodi container. My problem is that when I fill it the level is much higher than my water level in my sump. I have had occasion where my top off has turned on and created a siphon adding more water than is necessary to my sump. My question is what can I put on my line going into my sump to stop a siphon from occurring?

Nothing but move it. cannot control physics without another tool.

+1. I don't know of any way around it either. I have the tunze and I have the same problem. I just run the reservoir 3/4 full

may have a solution....do you have any pics of your ato setup?

setup an air-gap valve, make sure that valve is higher than the highest water mark in your ato tank.

Can you explain an air gap valve?

run the tunze ato line to the top of the container from there transfer to pvc cpvc maybe go into the side of a T top side of the T a short pipe bottom of the t plumb down to the sump
the air allowed into the pipe will not allow any siphon

This is what I was going to suggest. Run the ATO line up and into another pipe(set up like a drain) that will carry the RO water into your sump. Since there is a break there, you can't physically create a siphon.....
