Kevin can't make it to the Cities until Friday, family members dropping like flys, not good. Your system is built but I have been thinking we should go with a single tank on your system and a check valve. The single tank can feed both your RO and DI sides and the check valve will keep you RO side from feeding back. Sorry for the delay.

Sorry cleared my box out. No problem about waiting till Friday. Since I'm typing... So the water will run through all of the stages but the DI and be stored in the tank and then if the reef valve is opened it will run from the storage tank through the DI unit on its way to the spigot? If it's going to the cooler it will run directly from the tank bypassing the DI unit? What's the reason to not DI drinking water? Cost where it's not needed?

It is bad for you. First the water is hypostonic, so it will cause cells to burst. and by drinking DI water you don't get salts/electrolytes that you pee out and you deplete your system of them

I tried drinking 18MOhm watert at work anumber of years ago and it made my mouth numb from the cells bursting

Epidemic, I would find that hard to believe. RO water would be fine to drink (really not sure about DI, in all honesty). We take in much more salt/electrolytes than we need, hence the reason we pee some of them out. Now if that was the only thing a body took in, then yes, it would eventually deplete us. Take a TDS meter to a bottle of water, I'll bet the TDS is less than 18.

DI water is bad to drink, it will eat the enamel off your teeth.....ask your dentist

Here is all you ever want to know about drinking DI water. Derek, it's from your buddies at the WHO

I agree!

I bet most bottled water has a very low TDS (now I'm going to have to check tonight). Guess I should show this to my wife, then we can throw out the britta filter and stop buying bottled water.

Amen, The wife has some reading to due tonight and then the TDS meter will come out. I would love to get her off the bottled water and brita kick. It is a absolute waste of money IMO. IIRC my tap water TDS was 50 or less to begin with.

otolith · 01-04-2006, 08:29 PM

Wow, I think mine is in the mid 300s

redwinger · 01-04-2006, 08:38 PM

When we moved in our water was so hard and nasty we purchased some softner/filter that they use to filter water on the Space shuttle, which I thought was overkill. But the wife insists on buying frickin bottled water and then filter it again through the brita pitcher.

otolith · 01-04-2006, 08:45 PM

By her filtering it through the britta pitcher, she's probably adding stuff back.

epidemic · 01-04-2006, 09:34 PM

Just because water comes in a bottle doesn't mean it is filtered. I heard a while back a french comapny got cought using tap water and bottleing is minereal water..., I guess you never know.

HFG · 01-04-2006, 10:08 PM

Faz what is the average gallon life of an RO membrane?

Tutmos · 01-04-2006, 10:10 PM

Not just french companies. A lot of American brands do exactly the same thing, use municiple tap water and bottle it. I think 20/20 had something on it a couple years ago. IIRC it was some company that used Houston tap water or some similar city and had a label like Glacier Pure or some purity image evoking name.

I should also mention that Filmtec, who makes the RO membranes is about two blocks from my office. I always wondered what they did and why they needed such big Air units etc. and now I know

. They want everyone to know they've gone 1 year accident free btw. There's been a huge banner on their building for months announcing it. Maybe they're hoping for a workmans comp insurance break.
