RO/DI water storage?

[Anonymous]

Is it OK to store my RO/DI water in the metal storage tank provided in the drinking water kits? I have been told the water can leech out some of the metals in the tank.

Any thoughts? If giving an unsubstantiated opinion, please say so.

I don't think this is a problem and have always used a storage tank. The water goes into the tank ahead of the final stage (the DI) and the water comes out at 0 ppm TDS (when filters are new).

hi.
Store RO water in the storage tank, not RO/DI. Do DI on demand when you need it. The storage tank has a plastic bladder that hold the water, and there is minimum contact with metal.

Metal leech out the bladder tank is false if you use it to store RO. Who is spreading this misinformation? :evil:

Why should I make my DI water on demand and not store it in the tank. If I want to do a water change I don't want to have to wait several hours. I would like to store my DI water in the tank and then have access to 4 gallons at a time.

Any problem with this?

hi.
You can make 4 gallons of RO/DI from stored RO in less than a minute. All it takes is just open the valve on the bladder tank, and let it past thru the DI cartidge.

I think people are confused about the rate of DI production because they attach it to a RO membrane. RO membrane can only make 1 to 10 gallons of RO water from tap in a hour for non-commerical unit. But this is not the case for DI.... DI is almost instant (use bigger tubing if you don't want to wait 50 sec.).

The problem with storing RO/DI is that it is a very good solvent. As I said, there is no wait in make RO/DI from RO (stored in your bladder tank), but if you insist, there is nothing really bad about storing RO/DI. It is just more convenience to store RO, because many people that I know also drink RO water that is post-filtered.

Thanks for the reply. I never really thought about it, but you are correct. The RO step is obviously the most time consuming part about making water.

Thanks again.
