Hi there, so i have been avoiding getting an RODI unit because i have no idea how to set them up and trying to google it just confuses me more. What is the simplest unit i can get that will still get the job done?

I couldn't agree more.No need to go small, will end up costing you more for and may not give the best quality water, even a full size one can be stored away in a cupboard until needed, they are very easy to install in a number of different ways, such as under the kitchen sink, removed and stored away, outside using the garden tap, pumped in permanently...how would you want to set yours up? Will be easier to help narrow the advice down.
All they are in 4-5 filters that you run water through, not complicated at all.
Are you running directly from your membrane into the di? I only ask because I know of other users on here with well water who have had to allow their ro water to off gas CO2 before putting it through their DI because it was depleting their di quickly. Or it could be that even with a good rejection rate you would still have higher than normal tds on the water going through the di.I’m by no means an expert but I’ve got a BRS triple DI tied to my whole house R/0 I got from Amazon. super easy to setup and use. Very reasonably priced I’ve got less than $700 in my entire mixing station and its setup to pump my RODI and my saltwater up from my basement to the top floor where my tanks are. I’ve got the most garbage well water on the planet somewhere around 1900tds and the RODI tests to 0TDS consistently. I can get about 150 gallons out of my anion resin and about 500 gallons out of my cation resin before having to refill it. The mixed bed hasn’t been changed yet and I’m about 900 gallons in.
BRS has some awesome videos that really helped me a lot.
That is why he is running separate anion and cation. The CO2 depletes the anion much faster so if they are separate you are only changing out the anion more often instead of a mixed bed, which would still have plenty of life left in the cation.Are you running directly from your membrane into the di?

I understand the reason for running seperate resins, but if it were me and I had the option to let the CO2 off gas so that I wasn't quickly depleting either resin I would. Only getting 150 gallons from the anion isn't very good. It still could be that it gets depleted so quickly because at 1900 tds water coming in he must still have pretty high (compared to most people at least) tds water going into his resin.That is why he is running separate anion and cation.

I thought you didn't understand why he was running them separate. My bad. I've always read it is a pain and takes a lot of room to off gas. There apparently is a way to do a whole house solution but I don't know the cost. At 1900 tap tds I would also consider adding a second RO membrane to reduce the tds further. I have over 400 tap tds and my tds after the membrane is 3 to 4 so I would think he is looking at 16+ after the membrane.I understand the reason for running seperate resins, but if it were me and I had the option to let the CO2 off gas so that I wasn't quickly depleting either resin I would.

Either way I was just trying to point out a potential way to make his resin last longer.
I've never needed to off gas but AFAIK you just need to store it in a container for a day or so and then pump it through the resin. I would personally do that instead of replacing resin as often.I thought you didn't understand why he was running them separate. My bad.

It runs through a carbon polishing filter just past the 2nd RO membrane it leaves that filter somewhere around 150tds. I figure bulk resin is relatively cheap and I’ve already got enough steps in making water without adding more lol.Are you running directly from your membrane into the di?
