Prob a dumb question regarding ro unit

[Bradsreeftank21]

Im looking at buying new aquatic life ro system, I watched installation video of the unit and was wondering if I can just have a valve on the filtered end of unit and then whenever I need water (20 gallons) I could just open the valve in bucket? or must I run the tube downstairs from under kitchen cabinet into a separate holding tank?

Apologies in advance if I am a little confused on the second question. The unit should only be controlled by the faucet it is connected to. If a valve is placed on the filtered water, and it is closed, then the unit would have water flowing out of the waste water outlet only. Not sure what affect that would have on the unit, but something to consider if installing a valve on the filtered water outlet.

Simplified answer = Recommend only controlling the RODI unit with the faucet alone.

Turn on when needing water and turn off when done. Set an alarm, so the active RODI unit is not forgotten and causes a slight flood.

In most cases this is NOT true. Most RODI systems come with an Auto-shut-off valve installed. When you shut the valve, water stops pumping, including the waste water line. I have always had my RODI systems hooked up with a simple John Guest ball valve on the end of the clean water line (post DI). When I want water, I open the valve and fill the bucket. When the bucket is full, I close the valve and go about my day. Easy peasy!

I agree, however OP indicated interests in "aquatic life RO system." This is the same unit I use and it does not come with a shut off valve. It is directly controlled by the faucet or any other water valve before the unit that does not come with the unit.

With that in mind, I am sure there are plenty of other RODI units that have a valve of some sort, and I recommend OP research some other units if a more remote shut off is required.

If the unit doesn't have an auto shut off valve, just purchase one and install it. No need to get a different RODI. That being said, there are definitely other units out there that have the ASV included.
