ATO turning on often questions

[tidus10]

Anyone else notice their ATO is turning on a lot? Is there any way to make the ATO not turn on so often?

If you can figure out how to have less evaporation your problem will be solved. :wink: Also, make sure your ATO water line isn't under water, it will create a suction and cause water to drain back in your ATO container. That would cause your ATO pump to kick on a lot.

I have an anti siphon hose attached to my ATO because my ATO res head is higher than my sump head

Install a timer. Only allow it to turn on every so often.

Yes, either use two float switches with a set distance between ON and OFF to open and close a solenoid valve or a digital sensor such as the Spectrapure UPLC-II uses which can be easily adjusted anywhere between 1/10" and 4" differential at the touch of a button. One switch or a float valve will never be efficient and will lead to TDS creep issues and short DI life if you feed it directly from the RO/DI.
