R/O auto top-off setups?

[Ereefic]

I ran a line from my RO to a holding container with a float valve. Just before the float valve I put a JG valve. After the container has filled up and shut off, I just close the valve. When the container is getting low, just open up the valve and let it fill up.

It will take my container several weeks before it needs to be filled up again, and it won't be turning on and off to keep it full.

It's not totally automated, but easy enough to open and close the valve every so often.

That works too, except for me. LOL, I'd wake up the next morning and think "Did I turn the RO off last night?"

And probably didn't

It won't flood, the float valve will keep that from happening, but it may have kept the contaier topped off over night, not a big deal really since there is some play in the float valve.

That sounds like a good idea, but really I think if i'm gonig to bother with it, I want it to be fully automated. My goals is to be able to leave for 2-3 months without attending the tank, Of course I would have someone to feed and check up on it.

Thanks everone!

I'd laugh if it wasn't the truth. I've done this too many times before I came up with a simple rule: No running water if I'm not 1) in the house, and 2) awake. In addition, whenever I turn on the RO, I set a timer in the kitchen to go off whenever the amount of time has elapsed that will get my RO to 80% of the water I need, and I also physically carry around the RO wrench on my wrist like a bracelet to remind me. I've also put the wrench on my pillow to remind myself to shut off the RO before I go to bed.

Oh, and I use this topoff setup

feeding into a Geo kalkwasser reactor. It works like a charm.

I need to do that too! about 70% of the time I leave it going over night or just plain forget about it... and then I have both waste water and RO water all over. I use the waste water to fill up the washer so it makes a pretty big mess.

Aquacontroller!

 

[leeweber85]

I have an aquacontroller actually i have 2 I love those things, but what good is that going to do me with RO top off?

Hal- That setup looks pretty nice, I'm a little confused on how it works though. Does it hook up to the RO and use a resovoir or does it just dump the RO into the sump?

The inline Selenoid water cutoff from auto top off. The double float switch. The slenoid plugs into the autocontroller DC4 or DC8. The float switches wire into the autocontroller I/O switch port. You program edita a command. If Float 1 and float 2 are open turn on SW1 (selenoid. Then If Float 1 is closed Shut Selenoid.)
I am going to use both float switches as a chec and balance. Also you canjust use the float switch to set off an alarm. Then log in via webserver and turn on selenoid yourself then off. Update screen to see when the float switch shows closed....

 

[leeweber85]

I kinda understand what your saying but that's a little more sophisticated than what I need. I also don't know if the ac2 or acjr are capable of telling whether a floatswitch is on or off. Thanks for explaining it though.

1 External Switch Input
If the AquaJr is purchased with the serial port option, then it has one external switch input which can be used to activate/deactivate devices in response to an external stimulus. Applications for the input includes connection to water level float switches, water pressure and flow sensors, and water on the floor sensors. The AquaController Jr program can be set up to signal alarms or act upon the input condition.

The water comes from my water source, in one side, through a solenoid, and out the other to my RO. This way there's no waste water being created when the solenoid is closed. The solenoid is controlled by the float valves. The RO then either dumps directly into the sump, or in my case, through a kalkwasser reactor and then to the sump. The Poseidon unit is essentially a fancy version of the double float switch systems you see on autotopoff.com and topoff.com.
