RODI help needed

[Rookums Reef]

It looks like you’ve got the blue and black lines swapped. One way to tell is the RO water should come out of the port that protrudes further out than the other. An unrelated thought is to maybe swap the 3rd canister to filter before the RO only to avoid sending extra TDS from the carbon to your DI.

Switched them and the flows are better, membranes making some noises, maybe lack of pressure? Oh it's stopped now and all I hear is water Water is trickling through resin nicely. Gauge says 50psi. Thank you so much!

I agree assuming the black lines is the waste lines. I also dont think the asov is right though. Output of third carbon should go to the top of the "in" on asov and the top "out" goes to first ro membrane. The bottom side of asov should be fed from "good" ro output of second membrane and output to DI.

I have it coming from the membranes, I thought that's how the 4 stage gets hooked up but with all the changes and additions I must've been getting my signals crossed? I also forgot to order any blue lines. I only got red and black to import/export water from the hookups, my bad. I'll add that to the next brs cart. I like the color coding and this is a gross violation of that!

Glad you got it worked out. This forum is awesome and a great community. It’s awesome to see how many people jump on to help out.

I thought they looked reversed. Glad you got it sorted!

It looks like your ATO is plumbed correctly. As another rule of thumb the side with the screws is the low pressure side. The side without screws is high pressure. I saw a couple comments wondering if it might be wrong. Just wanted to give some insight there.

Thank you, I'm always looking for those nuggets of knowledge!! Not one thing I saw today mentioned that!

It's an awesome asset to have, I'm thankful! Gonna start my build thread and be an productive member!

Sweet looking forward to it. I love build threads

Got everything mounted and running, the water going to first membrane is louder than the booster pump? What am I missing or is this the way?

Why do you have what look like a carbon block after your membrane?

Not sure why you would get water noise. Does the noise change when you open and close the flush valve?

That's the way its been setup since I got it. 1 sediment, 1 carbon then membranes then carbon and 2 resins.

The noise is only when booster pump is on.

I have never seen a system configured like that before. I see no benefit by having it like that. The carbon block main purpose it to protect the membrane.

In you picture the flush valve is open does the noise change when you close it?

Here is my sketch schematic and final build. All plumbing colors are on schematic.

Runs quiet, booster set at 80 psi for input to RO membranes. Relocated nearly all plumbing to be visible.

When I close it my pressure goes off the charts, so I don't do that.

What does off the charts mean? Can you adjust the booster to 80 psi or so? You are going to be making lots of waste water running with the flush valve open.

 

[homer1475]

Your not supplying proper pressure with the valve open. It should be shut when making water.

Whats off the charts pressure?

And I agree with the carbon block after the RO stage, it's useless. The main point of the carbon block is protect the membrane from harmful stuff like chlorine. Having it after the RO it's doing nothing.

Is @Buckeye Hydro still around these parts? I know thier still a sponsor, but have not seen them on the forums in a long time.

If they respond, they will get you setup properly, and with the proper filters. I honestly would not hesitate to give them a call during normal business hours. Russ has always been a standup guy, and I've seen him many times have someone call him to help with RO/DI problems even if the unit is not from them.

It goes past what my meter can show. I thought the flush valve was to backflush to membrane?

 

[homer1475]

If your off the chart with the valve closed, you don't need the booster. And quite possibly something is plumbed wrong. Or is it off the charts with the booster pump running?

The "flush" valve is to flush the membrane with low pressure high flow water. Basically flushing the membrane of permeate from sitting with water in the canisters.

When you close the valve, your supplying high pressure, low flow water to the membranes so they can push the water through the membrane instead of just flowing over the membranes.

How many psi is that?

as @homer1475 said the flush valve bypasses the flow restrictor to flush. It does not back flush the membrane

Russ does not seem to be on here much any more but this is a good information post in the sponsor forum
