The one you design with plenty of safeguards!

There's really not one that is integrated with the Apex out of the box. There are stand alone systems of course but if you want one that's integrated and controlled by the Apex, you have to cobble something together. Plenty of threads by people that have done it along with program examples. Just need to use that search tool a little. But remember that floats will fail and account for that when you design something. And, a top off is way easier than automatic water changes.

I have a 55 gallon drum in my basement that I have RO water in. It pumps upstairs via a Mag1800 (from basement to first floor).

For the top off, I have three floats. Float 4 and 5 are around a 1/2" apart (maybe 1/4") vertically. The lower one is float 4. I added a third float that is around 2" higher. This is float 6.

The pump is hooked up to an outlet on the EB8. I have this programming.

Fallback OFF
Set OFF
If Time 07:00 to 07:01 Then ON
If Time 20:00 to 20:01 Then ON
If Switch4 OPEN Then OFF
If Switch5 OPEN Then OFF
If Switch6 OPEN Then OFF
Min Time 005:00 Then OFF

I have the floats set where OPEN is up and turns the outlet off. This way if a wire comes loose, it defers to off and not on.

I also have it run no more than two minutes so if something happens wit the floats it is on only 2 minutes.

Along with the above, I get an email if Switch 5 or 6 are open.

Works good for me so far.
