I have a RO/DI unit.

There are two outlets. One for RO only and one for RO/DI. I have my RO hooked up to my ice maker and a faucet for drinking. There is also a bladder storage tank for holding water on this line.

My RO/DI is of course hooked up to my tank.

I have noticed that when I am filling buckets or tanks up with my RO/DI line, it bleeds my RO tank. So I guess I am actully filling my tank up with RO water.

Am I doing something wrong? Why would it reverse my flow and take RO water and go into the RO/DI line?

Should it be doing this?
