ATO Reservoir Help

[blstravler]

So my ATO Reservoir will be in my basement and I’ll use the Neptune ATK to move water up to my sump as it evaporates. However I’d like to make my ATO Reservoir self filling. I could put an optical sensor OS-1-M and Solenoid Valve SV-1 on the reservoir but each time a little water goes up to the tank then I’ll only be opening the solenoid for a brief period of time and I know that’s not good for the RODI unit. So for some reason I’m stumped on how to set this up.


Do I need to put the sensor closer to the bottom of the reservoir and maybe make it so once the sense is dry it opens the solenoid for x time to fill the reservoir?


Any help/ideas is greatly appreciated!

I would think you could put one low to turn the solenoid on and one up high to turn the solenoid off.

I do this for both my ATO as well as my NSW reservoir for my auto water change. I have water level sensors at the top and bottom of each reservoir. When the water gets down to the lower sensor then the apex will open a solenoid that starts the RODI filter and fills the reservoir. Once it reaches the top sensor the apex closes the solenoid again. I have a few safeguards in place to help prevent a flood if the solenoid happens to fail.

There are a lot of details in my build thread here in post number 22:

Thank you - this exactly what I was looking for. So in reading through your post it sounds like at the very basic level in your ATO Reservoir you have two sensors one at the top and one at the bottom. Bottom turns Solenoid on and top turns Solenoid off. Again this just the basics of what you are doing. You have multiple redundancies behind that but does this sound about right?

That’s right. Briefly, to refill the ATO there are two solenoids... one before the RODI and one after the RODI. This way if one solenoid were to fail it would prevent the water from running indefinitely. Additionally the one before the RODI allows the RODI unit to be depressurized when its not in use. And the one after the RODI also allows me to direct water into the ATO reservoir. (I have a T on the output and another solenoid that will direct the output to the NSW reservoir for my ATO when that needs to be refilled)

Finally, as a last resort the fill line for the reservoirs goes through a mechanical float valve, so if something were to happen and both solenoids failed or the system was left on the float valve would close when the reservoir was full and that would prevent a flood.

I’m happy to share my Apex programming for this when you get ready to set it up

Good luck
