Help with ato!

[Chiefmaster30]

So I have an ato that has been running fine for months. I am going on vacation in the morning and only thing I changed is my ato container. I moved my ato pump to a bigger container and ran a new tubing that’s longer from the pump to the sump where my top off water enters. Done this yesterday. Get home today and notice sump water level is way higher than than ever and my float switch. The pump isn’t continuously running but the outlet seems to be putting water in my sump continuously. Is it just more runoff from the bigger container and longer ato tube or ???

If other end of the tube is lower than the water level of your container water will continue to flow in sump even the pump is not running.
Happened to me before.

Sounds like a siphon

How do I get around this?

So the water level in my container has to be lower than my ato outlet in my sump?

Run the tube up to the display. Had the same problem, that's what I had to do. Caused a syphon as the water level in the container was higher that the water level in the sump,

Thank you so much! In panic mode and can’t think!

Make sure you tube did not touch the water level in display tank. If not when the pump stop it will siphon back to you top top off container and flood your house.
This also happened to me LOL

Another way around this is to install a RO T fitting at the height of the water line in your ATO then add a few inches of tubing higher than the T.. If you don't want it pumping up to your DT that is, most standard ATO pumps struggle at those heights...
