I think i set mine up wrong when I reconstructed it and can't find my original instructions...it is from buckeyefieldsupply...will email them if no one has it here.
Anyone have instructions for 3-stage RO/DI hookup

randal, I will give you a call sometime, thanks!

Okay, but look back at my post again. I am still curious about the bypass issue. I was told in a college biology class that humans should not drink de-ionized water.
stage 5 is DI, that's what i figured.
stage 6 (in the diagram) is the "taste" filter according to the manual that came with my 5 stage.
So if you open the valve on stage 5 (in the diagram) and turn off the valve to the pressure tank water from the stage 5 doesn't go into stage 6, correct?

Adam we really use the drawing more to help people reset there system when they are having problems. In the first drawing you can really drop the fifth stage inline carbon as it serves no purpose. If we build a system with the number two setup we put a check valve before stage 5 to prevent drawback of DI. You are correct on DI being unhealthy to drink.

As long as there are questions here about RO systems....
I have mine set up to auto fill the aquarium, faucet at the kitchen sink, and a faucet in the basement for the ol' ladys plants.
The long run to the kitchen has a fairly large pressure drop after filling a large glass of water. My system has a booster pump on it already at the RO unit. Will adding another pressure tank at the furthest faucet remedy my pressure drops and give me additional capacity available?

If you open the valve on stage 5, the water from the tank will run through the DI. Correct. If you open the valve on stage 5 with the faucet off, the water will not run through stage 6 at all. Water follows the path of least resistance. If you turn off the valve on the tank and open the valve on stage 5, the RO unit's water will output without filling the storage tank.
HTH.....
Guzz,
Does your Unit have a pressure switch for the Booster pump? If so, adding an additional tank and increasing the set point for your pressure switch will eliminate the immediate pressure drop. I have my unit set for 80 psi with a 10 Gallon tank and I get tons of pressure for the first 5 gallons or so.
There is no problem with drinking DI water but I find it tastes very odd after going through the DI stage. RO water is a better bet.
Feel free to search RC about the effects of drinking RO- RO/DI water. The topic has been beaten to death several dozen times here and I get tired of hearing the squishy sound from repeatedly beating my head against the wall...

OK this keeps coming up from drinking water sales people and I'm on the RO/DI side sooo I could be wrong. Please read this link and tell me what you think about drinking DI water.

Fahz,
I've seen that one dozens of times. That study doesn't say specifically anything. It says "Can" "Maybe" and "Possibly" with little to no human testing. It does specifically say that drinking water is NOT the primary source of most of our mineral intake.
My position on the whole topic is best expressed by this:
I don't mean to be rude, But not having noticed any horrible after effects around my place (for the last 15 years) from low TDS water I tend to doubt the Chezk (or however you spell it...) republic's position on the topic.
Finally, I think we've done enough Hijacking on this thread...
Regards,
RandalB

In regards to the effects of drinking ro di and them being bad for your health...hmmmm
Yes RO DI water is very light as far as osmotic pressure goes and yes if you were to base your diet solely on RO DI water and nothing else you certaily would one day face a cell wall colapse.
BUT> I think that you would die of starvation before this would happen. Secondly as Randy mentioned if you take one bight of steak you have recaptured the small trace of minerals you have lost from the water.
Now if you go back and do a search on this subject you will see that I have never been an advocate of the mineral loss theory and the only reason I can say that DI water is not good to drink is because it doesnt have any taste.
I will repeat one statement I made in a past thread.
People become comfortable with things they recognise. this applies to the taste of food and drink as well.
The reason we like foods and sodas with sugar in them is because we recognize sugar as a taste we enjoy. This is a substance that over the years of consumption we have learned to identify very easily. Now the same concept applies to water. If we have been drinking mineral water or even hard water for a long time the minerals and hardness become identifyable to our taste and basicly we identify this as the taste of water. This is not the taste of the water it is the taste of the things in the water. The same concept could apply to soda, if you were to all of a sudden remove the sugar from the soda you would no longer enjoy it You would say that it tasted terrible and you could more than likely know it was absent of sugar and blame the bad taste accordingly. Now the problem with the water is that over time you have attributed the taste of the water to just being water and were unable to identify the individual minerals in the water that actually made it taste the way it does. SO when these minerals are removed now the water tastes (SUGAR FREE) and you no longer enjoy it as much.
As stated by DR Arthur L Guyton in 1991 The kidneys control the overall concentrations of the constituants of body fluids. It filters about 180 liters of water per day, over 99% is reabsorbed and 1 to 1.5 liters are eliminated as urine. If the osmolality of the fluid to be filtered by the kidney is lower than normal, nervous and hormonal feedback cause the kidney to excrete more water than normal and maintain the ion concentration in the body at normal values. The opposite is true if the ion concentration of the fluid to be filtered is higher than normal. The kidney homeostatic mechanism keeps the body fluid osmolality normal.The three basic hormonal and nervous control systemstriggered by abnormal ion concentrations are the antidiuretic hormone (ADH) from the pituatary gland, aldosterone from the adrenal glands and thirst because thirst is caused by a 1% rise in osmolality. Because of these kidney control mechanisms, drinking one liter of water would cause the urine output to increase about 9 times after 45 minutes and continue for about two hours. Thus the concentrations of solutes in the blood and other body fluids are quickly maintained by the the kidneythrough homeostasis. these control mechanisms keep the sodium concentration at 7%. Calcium concentration is controlled by parathyroid hormone to + a few percent in the extracellular body fluid. Also, Saliva increases the ion concentrations during water intake. The concentration of sodium chloride in saliva is typically 15 milliequivalents per liter or 877 mg/L that of potassium is about 30 milliequivalents per liter or 1170 mg/L. As low TDS water is consumed, it is combined with saliva which increases the TDS before it reaches the stomach to be absorbed. Each one millileter of saliva can increase the TDS level in eight ounces water consumed by about 10 mg/L. Basicly any changes from normal ion concentration will be corrected in one minute or less because of the fast pace of water through the cell membranes. Sosmall changes in osmolality (ion concentration)
are quicly brought to an equilibrium........
Beyond all of this If you wish to drink DI water I would suggest drinking non color change DI resin. Non color change resin is rated potable and approved for human consumptiom where color change resin is not.
Take care all and happy readin
