Electric RODI valve with float valve; $50 shipped
I used it to connect my RODI to my ATO reservoir, and be controlled by my apex. It allowed my ATO reservoir to be filled twice a week(what I programmed it) by my RODI. Once I did this, I never had to refill my ATO reservoir again. It was set up with 2 fail safes. 1st is a float valve and the second was 10 min longer than anticipated to fill the reservoir. I put a line on my tank so I knew where the fill mark was. If it never went under the line, then the electric valve failed, if it went over the line, the float valve failed. I never had one issue with the setup for almost 2 years. Worked like a charm. I leave for days at a time and this made life WAAAYYYY easier. Tore down my tank, that's why I'm selling it.
Its currently set up for a 20 gal tank(although you could use a different size tank, just have to adjust the float)
