Rodi under sink install question.

[griss]

Like this? Had to make sure since I'm adding the 2nd membrane..


Keep in mind, I don't even have a canister on the di part. I figured why put resin there since I'm weeks/months from tank ready.


Should I just install canister and let it fill with water?

You're sure trying to stump me aren't you

I've never run a system with 2 membranes, even when I had a 450 gallon DT and 150 gallon sump. But, looking at your diagram, that should work.

Yep, no reason to put resin in the DI cannister if you're not making water for the tank.

oh and brs said they recommended pump after sediment

Yep, that's what I would do.

I guess the membrane is supposed to take mine from 75gpd to 150gpd..so that why I added.


So just to verify. Install canister and let it fill with plain water?


Sorry, almost done with the question and appreciate all the help

No dumb questions, never apologize for trying to learn. That’s what we are here for.

Yes, just leave the DI canister fill. But, close the valve on the output as you’ll be wasting water if you let it run until you’re ready to produce RODI.

If you want to post some pics or a short video of how you have it set up, that might help me double check everything for you.

ok, will do.

ill first make a diagram and post to make sure before I start to plumb. so on aquatec website they recommend> (It is recommended that an in-linen sediment filter (150 micron or 100 mesh) be installed at the inlet side to keep foreign debris out of the system.)
then they recommend installing before the carbon filter to keep carbon out but brs says after sediment filter. not sure how I would accomplish doing both of those. So I guess before sediment will have to work?

I’m not sure I understand the question. Are you talking about where to install the booster? If so, mine is between the micron/carbon filters and the membrane.

Here’s how my system is setup and it’s worked flawlessly for years. After flushing the membrane for TDS, I get about 7 out of the membrane and zero after the DI. It’s been over a year since I replaced my DI resin and it’s still going strong.

- Micron filter
- Carbon Block
- Chloramine Cartridge (my water company uses chloramine)
- Booster Pump
- RO Membrane
- Cation Resin
- Anion Resin
- Mixed Bed Resin

Yes thet are saying it ruins the pump if it's installed after the carbon. So they (aquatec) want it installed after the sediment filter but before the carbon filter. Brs says after sediment filter but I can't go in-between sediment and carbon on my system without modifications.

So I guess I'll go before the membrane same as you. edit: wait, it doesnt say it ruins pump just says install it inbetween carbon and sediment with no other explanation.

they are want another inline filter installed on inlet side of pump to keep foreign debris out? do I really need that?

 

[griss]

I think it’s overkill IMO. I’ve been running mine for years with no issues.

one filter in front of the booster is enough.

maaaaan hopefully we gonna finally get this thing up and running before the week is over.

The way the AWI is configured (IMO), without modification, it can only be used as it was intended...for both drinking water and RODI. This is because capping off the DI AFTER the ASOV puts pressure on the ASOV and will shut the system down.

If you want the option to make either drinking water or DI water, here is what I would do (you shouldn't need any fittings but, might need some extra RO tubing to make this happen). See diagram below:
- Instead of having the RO water line from the membrane going to the T-Fitting, have it go to the ASOV (green arrow).
- Then, put the T-Fitting on the output oh the ASOV (purple arrow).
-

I got a little confused.. trying to connect.

So the way awi is designed now it can be used for ro or di? and what will be the diffrence the modified way?


also it says connect purple arrow to output but I thought that was the in side of the asov? meaning "in" side is left?

 

[banthonyb71]

i think im just going to use this diagram for now because im really starting to confuse myself and ill have to worry about the di part when time comes

No, the opposite. The way the AWI is currently configured you cannot use it to make just RO. If the DI is blocked, capped or closed, there is nowhere for the product water to go. This creates back pressure on the ASOV and will shut down the system.

 

[banthonyb71]

Had to simply this until I get a better understanding of how the system functions. I'll wait til I have tank and modify.


My only question now is where do put pressure switch?

 

[banthonyb71]

Actually let me back track. Doubt that will be my only question

Should be my only question until I atleast connect this system

 

[banthonyb71]

No, the opposite. The way the AWI is currently configured you cannot use it to make just RO. If the DI is blocked, capped or closed, there is nowhere for the product water to go. This creates back pressure on the ASOV and will shut down the system.

But how would that be different if I had the complete system hooked up as designed?

Like let's say I had resin and the di chamber filled ready to make di water. Using orginal diagram. Wouldn't I be able to just shut of di switch and turn on ro switch and make ro?

 

[banthonyb71]

this diagram here. isnt this designed to just be able to shut off di when needing ro only? Not hooking it up this way just trying to understand what the differences are in this and the modified way
