OK to Drink DI Water?

[fastcar01]

We just ordered an RO/DI system. It has a sediment, cholormine filter, carbon filter, membrane, and DI canister. We got the drinking kit as well (tank, faucet, polishing filter, floats/valves). I am wondering if it is OK to drink the DI water? The saleslady said it is fine but has a sweet taste and in case we don;t like it you can bypass the DI canister for the drinnking water. Is there any problems drinking it or is it actually better for you? Thanks

It is fine unless you plan to only drink gallons of water a day without eating anything. I have been drinking di water for years with no ill effect.
If you want it is very easy to bypass the di.

I agree a tee and a couple valves and you are in buisness. It will save you on DI resin pretty quickly if you intend to use a large amount for drinking/Cooking.

A drinking water add on kit is available from most RO/DI companies.

drinking DI water will strip minerals from your body.

use the drinking water kit for sure...

The unit does have the bypasss valve included, plus the drinking kit. I am assuming you would have to drain the storage tank once you opened/closed the valve and then let it fill back up with the new stuff.

that is very true!!!!

waste of water lol. is your tap that bad?

[ClayWagner]

Many studies prove that tap water (hard water) is beneficial. Mg+ and Cl- (help control blood rate/flow...only help as an ionized bond though, don't go drinking magnesium or chloride!) from the water have been linked to improve cardiovascular longevity compared to those who drink deionized or soft water. Just drink the tap water and save some money . Deionized water actually impedes cellular metabolism because the bare water molecules want to travel inside the cell to create an equilibrium of osmosis between the inside/outside of the cell. Can you tell I'm a micro/molecular bio major? Only good effects for DI water is that no impurities to be collected in the kidneys, but unless your drinking high TDS water (such as some bad well water), there's nothing to worry about. If you decide to use DI water anyways, it's highly suggested (like others said) to use a drinking kit.

The RO system we are getting has one canister with a Catalytic carbon/KDF for cholormine removal. Is it OK to drink the water that has passed through that? We are getting sediment, Cat Carbon/KDF, Carbon, Membrane, DI, final polish, but we can bypass the DI if wanted.

I drink my top off water all the time. I also drink tap and bottled, as I am aware of the lack of minerals in the "Fish water"

Drinking DI water does absolutely no harm to the human body. You could not possibly drink enough DI to ever do any harm. The studies that have been done are all inconclusive as they could not force enough water into a person and deprive them of any solid food to get a true study.
Use the RO bypass and stor RO water in the pressure tank for drinking and other uses and run presurized water from the tank back to the DI to make RO/DI water.

Doesn't drinking DI water cause instant brain damage and cause people to speak in tongues?

I thought I read that on the internet somewhere.

[sjm817]

I've seen several times from the RO/DI vendors not to use pressurized water through the DI, but I dont recall the reason.

Here is a diagram from http://thefilterguys.biz of how it is laid out:

[AZDesertRat]

The problem with pressurized water through the DI is really only a problem with small low capacity horizontal DI filters. With higher velocities you do not get good contact time thus poor treatment. With a standard 10" vertical cansiter plumbed and packed correctly its not a problem. I have seen testing as high as 20 gallons per minute with good resins and it still came out good. As long as you stick with the 1/4" tubing you should not have any problems with DI treatment. You will have a 1/4" ball valve on it anyway so if you find you are not getting the TDS or conductivity readings you expect just slow the flow.

As a former biochemistry/molecular genetics researcher, I agree with AZDesertRat--DI H2O is not dangerous or bad to drink. DI water molecules won't strip your cells of minerals, or make your bones or teeth dissolve. (People have told me that's what they think)

But if you were running a marathon, there are better things to drink than pure (DI) water. Sport drinks have minerals (electrolytes) that aid in absorption, and help replenish minerals lost from sweating.

Did you know Dasani bottled water is DI? You'll see it reads 0 ppm with a TDS meter.

agreed.. no probloms with drinking DI

it taste bad to me ( and now i know why i hate dasani)

just add a normal tee between the ro and the di.. have it run to your pressure tank.. and then add a nother tee next to that one and run that to your faucet)
