Upgrading RO to RO/DI

[demonbarber09]

I have an a RO system that I was gonna use for drinking water but now I want to upgrade to RO/DI so I could have drinking water and water for a mixing but I’m not sure how to go about it. This is the system I have. Let me know any suggestions on what to do

Did you check out the manufacturer website to see where they suggest adding a DI canister?

You need to add a DI canister after the RO and before the last 2 cartridges.
If you add it to the end, the re-mineralization units will cause you to burn thru resin. Plus You dont want to drink RO/DI water for a long period of time.
Also you will need to add a 3 way valve to shut off the water going to the DI canister when not making tank water.

I was gonna split so I only get RO water and not Di to drink. As far as connecting the DI reason I had that question is because of the re mineralization units. So is this still a 6 stage RO

Just buy online cartridges so you can add your own DI. There cheap and easy to add inline to your output water

That’s what I’m planning on doing but wanted to see if any one could based on the system I have on making sure everything is plugged correctly

I plan to do the same thing. On my system the demineralization filter can be easily removed and then will place a 3/8” hose on the faucet. But my system is different from your system so I don’t know if you can do that. My system is a tankless Ro filter

I’m trying to avoid buying a whole new on just for mixing water. I want to kill two birds with one stone.

Was not suggesting you buy a new system just suggesting if you can bypass the last two filters then when you want to make water for your tank just put a hose on your faucet. Maybe you can not bypass your last two filters I don’t know

It does not matter what you have or dont have, what maters is how much TDS you have coming out in your output. So I run 3 cartiridges and it last me years because I have pretty clean water to start with. If you have bad water or not that clean 2 will be needed to last longer. Ill post what I run below https://www.ebay.com/itm/162052406508?epid=1771964725&hash=item25bb137cec:g:umAAAOSwOGVauUoS

Your system is fine, its a typical ro system, and they all can be modified or added to or subtracting things you dont need. Your just adding a cartridge or two to clean water a little more then what you have now. Goal is 0 TDS

So I my question is should I should I split the line so the DI doesn’t get any water from the last two systems.

I think I could bypass it I still haven’t set it up yet for this reason

Let me phrase it so you can get the most out of what you have. For drinking water no heck no. Only use DI for mixing salt. So I would run like most here, using these long term meaning over decades. 1 pre filter, -- 2 carbon cartridges --- RO membrane--- DI cartidges ---- mixing container No need for anything else. Need a dual use system you can add 1/4 " T valves and more tubing to change water direction when needed

That’s what I meant I wanted dual use because I know you shouldn’t drink DI water
