Help me choose a RODI

[fermentedhiker]

I'm finally breaking down and looking at getting a RODI system. Hopefully it'll fix my hair algae issue(or at least not contribute to it).

I have a drilled well so Chorine/Chloramine are not an issue. It's been awhile since I had it tested, but it didn't have anything "bad" in it. Just a bit high in some minerals(manganese was the highest).

I'm looking to set it up so that I can have more than one faucet off of it. One at the kitchen sink for cloths irons etc... and one running to my ATO reservoir for easy refilling.

I was thinking of this unit from BRS;

Or maybe it's worth it have the inline TDS meters and get this one;

But I don't see a holding tank on either one. Is that something you source locally from a plumbing supply place instead?

a little research on RODI storage tanks. Based on size I can see getting one local would be better since shipping could be killer on something that heavy.

On a water system site it mentioned this about tank volume;


As your water demands grow, one thing to consider with a reverse osmosis drinking water system is the capacity of the RO storage tank. RO water storage tank holding capacity is dependent on INLET water pressure to the tank and the RO tank air pressure. Typically the RO tank capacity is 50% of the total RO tank volume (empty). Many popular systems come with RO tanks with storage and the capacities that range from 4 gallons to 25 gallons RO tanks and up. One of the easiest ways to extend the available filtered water is to add an additional RO tank.

So it looks like a 20 gallon tank minimum in order to fill a 10 gallon ATO reservoir without having to wait for the RODI to catch up.

Use a Brute garbage can with a lid, one of the grey ones.

Forgot to add - Set it up with a float valve so it shuts itself off.

With a well beware of elevated CO2 levels this will cause you to burn through DI very quickly. I would look into Spectrapure. They have a 4 stage unit for about $130 and a Maxcap for under $300.

here is a link to Spectrapures page on RC that has a lot of good info in the stickies

One thing to remember is Spectrapure is a specialized water filtration company that has been in business for 30 yrs

Spectrapure is my go to! Have used them for years. I too am on well water with crazy hard water and co2 issues. They worked with me to get the right system.

Its best to get the BRS you saw and also get the 150 gpd upgrade kit. It will be worth it in the long run. And for storage I use the Brute trash cans from Lowes and installed the auto shut off kit from BRS on the RODI.

[fermentedhiker]

If you use a brute trash can(or any other non pressurized storage) you need another pump to move it as well as the float system as a fail safe.

A pressure tank seems like a more elegant solution(if a bit more costly up front).

I'll check out the spectrapure units.
