BRS RO/DI System?

I was looking on BRS and found a very nice RO drinking water system that had the DI separate for aquarium water. I was wondering if others on the site had tried this RO/DI filter. I'm considering this setup as my family currently consumes a lot of bottled water. I'm mainly concerned with the drinking water quality more than the effectiveness as it appears to make zero TDS water. Anyone that owns this system with any feedback for it would be great.

I have the drinking system kit. The drinking water is not zero tds. Thats the DI water and you do not drink that. You drink the water after the RO but before the DI. The water has absolutely no taste at all. Makes great ice and juices. You can pull the expensive filter out of your fridge if you supply it with RO water. One thing I recommend and think it should have been included is the permeate pump. The RO membrane works by the pressure difference between the supply water and the permeate. As the reserve pressure tank fills the permeate side starts to increase in pressure and the pressure difference lessens resulting in tds creep. So when you go to make DI water your DI gets hit with a surge of higher tds water shortening it's life. The waste water powers the permeate pump keeping the pressure difference high. It also keeps higher pressure in the tank. Which fills up your cup faster at the faucet.
 
Thanks! Ya I know shouldnt drink the DI part. :) The all positive reviews on the site just seemed very odd. Figured I'd ask first since it does seem like a popluar item. Have you found any local stores that stock the filters for it? Or it only able to use the filters from BRS?
 
Usually the filters for all the RODI systems are of a standard size (10" ) so you can get the filters from many sources.
 
Because there's nothing in it, at all. No vitamins, no minerals, literally nothing. It's not harmful to your health unless you don't drink anything but DI water.
 
Most of the lower end DI like we use for tanks could leave traces of the chemicals used to DI sulfuric acid, and sodium hydroxide. Not stuff I'm looking to drink. :)
 
DI water will pull electrolytes and minerals from your body. I'm sure its a long effect and not drinking a glass and breaking bones lol.
 
also has no fluoride, so your teeth would weaken and the government wouldn't be able to control your mind anymore.
 
nothing wrong with it....Deionized water simply means that certain dissolved stuff has been taken out of it. It is a step below distilled water.

Most things that dissolve in water become ions. Ions are simply charged atoms (or groups of atoms). For instance, when salt, which is NaCl (sodium chloride), is dissolved in water, it separates into its constituent ions, Na+ (the + means it is positively charged) and Cl- (which is negatively charged.) So salty water, and also barbecue sauce and mineral water, all have lots of ions.

Most inorganic (not from living sources) compounds that dissolve in water will separate into ions. So when
water is deionized, most of the inorganic impurities are removed. It would not have any dissolved minerals or heavy metals like lead or mercury, for instance.

However, it could still have dissolved organic compounds, which don't form ions when you dissolve them. Examples might include alcohol, sugar, or more realistically, nitrates like you find in fertilizer or pesticides.

So deionized water could theoretically be bad for you. It could have bacteria or dioxin or rattlesnake poison in it.

But if you ever see deionized water in real life, it is basically purified tap water. The reason they make deionized water is that in certain cases, you don't want dissolved minerals in the water, but you don't need absolutely pure water. A humidifier or a steam iron might take deionized water, because deionized water won't leave white mineral deposits inside. Because it has relatively few ions, deionized is actually a pretty poor conductor of electricity. Apparently those spot-free rinses at car washes use deionized water, again because it leaves no mineral spots. And it is cheaper to make deionized water than absolutely pure water.

So you could drink it with no problem. I certainly would.

where's your bibliography?

It's not that it is bad for you, it's that it isn't good for you like spring water or mineral water. It's the same reason that you don't use DI on FW. In SW we take the water down to the bare bones H2O and then add back the proper seawater minerals. FW animals (humans included) need certain minerals that come from water. If you ONLY ever drank DI you might eventually experience some effects, but it's not going to poison you or anything. If you drank DI and took a mineral supplement every day, you'd probably be totally fine (other than the aforementioned potential chems in the resin ((which I had never heard of))).

sorry for the hijack BTW :)
 
Just an update on this. Got the 5 stage drinking water setup. Has a T, one way valve, and shutoff for the DI stage. Very nice setup. Took me about 45min to get it setup. Hardest part was drilling the hole in the stainless steal kitchen sink. After that it was really straight forward. The RO drinking water it makes is great. Haven't made any RO/DI water yet for my tank, probably will on Thursday or Friday for my next water change.
