I finally got my RO/DI unit and there are a couple questions I have.

I see on this site in pictures a well as other sites the unit under a tank in the stand. As my tank (stand) doesnt have a water hook up behind it, how are you getting the water to your unit and where is the water stored ?

The instructions show just an under the sink mount with a faucet and a 4 gallon tank. Im assuming all this can be changed and rigged to fit just about anywhere. I need more than 4 gallons for a water change.

I was considering hooking it up in the garage and letting it dump into a barrel of some kind. This way I can run it off a "T" I can install at either a hose bib or the cold for the washing machine. I can run it as needed and let the water sit (not for very long) till needed ? Not to mention the container will hold more than four gallons. This kind of hook up wont mess with the filters or unit, not having the water running constantly?

One more, in the instruction book, well pages it mentions working pressure, pH range, hardness above 300 ppm, iron/rust problem as well as bacteria and these may require additional parts. Here in NW San Antonio are any of the above a concern?

Any help appreciated and thanks in advance !!

If you got one of the typical aquarium RO/DI set ups (like Kent, spectrapure, etc) then I think what you're wanting to do is fine. Most people just hook up the filter when needed, collect water in a bucket or tub, then use it for make up and/or water changes.

Working pressure is how much pressure you're putting on the membrane, basically determined by how much pressure comes out of your pipes. A plumber once told me that in a good case, (lots of pressure) that's 40lbs/in2. Much more than that causes a lot of leaks in typical house plumbing. I think most filters are rated to handle a lot more pressure than that. The basic issue is that your filter will put out more water if you have high pressure. I've really noticed this in my new place. As far as rust/iron/sediment, your filter must have some sort of a prefilter; usually it looks like a ball of string in one of the canisters. That's what its for, but if you have old pipes, you can help things out by running the water for a few minutes before hooking up the pump each time. Bacteria is (hopefully) a non-issue on this side of the border, and I'm sure the filter folks' lawyers have something to do with that bit being in the manual.

Thanks

Ok, after looking it over ... I can simply hook the hose to it (or a new one just for RO/DI) run it till I have the quanity needed and take it apart leaving the unit on the wall ?

Yes, but with the two tanks and the distance with no common wall Id have tubes and hoses all over the place. This Im sure you know doesnt work well with kids :lol: .

Well we will just have to get the home builders to start installing in the studs behind drywall :shock: .
