Ro help

[Mr. Gonzalez]

if your TDS after going through the membrane is still that high, either you have a bad membrane, you installed it backwards, or it's not seated properly.

Take apart the housing and check that the membrane is installed correctly and if that doesn't fix it, replace the membrane with a new one. If the replacement works, then contact whoever you bought the bad one from and ask for a refund.

Thanks gonna try this will update once I do.

One other question... You say you're not getting any waste water. Is this true even when you open the fludh valve? If so, that line may be clogged.

 

[anthonygf]

I disconnected it at this end not sure if this is correct. So water runs through the sediment the carbon then the membrane and then is coming out that line I have disconnected. It's reading 405 ppm.

That is the waste water going to the drain. You need to test the water at the yellow line, that is filtered and it is just before DI resins.

 

[anthonygf]

That valve on the blue line should be your restriction valve. What is the value of the restriction valve?

 

[anthonygf]

I also have a 3 way TDS meter connected to the lines, 1 for just before membrane, 1 after membrane and the 3rd after DI resins. You should do the same.

The yellow is the waste water line.
He is testing the correct line.

edit: you're right, sorry!

 

[Mr. Gonzalez]

Disconnected everything and just ran the line directly to canister with membrane installed. The yellow line has nothing coming out. Took out the membrane and I have flow coming out of both.

 

[EeyoreIsMySpiritAnimal]

Ok, @anthonygf is right... You have the waste and "good" lines reversed. The yellow tube should be plugged into the top and the blue into the bottom.

("top" and "bottom" being relative to your photo)

Once you switch the lines, and the valve is closed, things should work right...

I'm sorry I didn't catch the problem before.
In this picture, your lines are reversed and the flush valve is open.
Close the valve (red circle) and reverse the lines (purple circle)

Need help with my ro. I searched and read other threads but now confused Korean than ever. I switched my membrane. Do I need to run off water before I start using the ro. Also I have no waste going out and not sure what is going on. All the lines are correct. I have new di that is a month old, carbon is new, and sediment filter is new. It's a 4 stage aqua fx system. Tds going in is 450 coming out is 113. Psi is 50. Water coming out way to fast. I purchased a membrane from Amazon for 100 gpd but not sure it was the right one. Any help is appreciated.

Also looking at this picture you have the TDS sensor located in the wrong place, that is the waster water going to the drain. It will always be high.

You are correct though when switching lines the restrictor needs to go in that yellow section between T's.

 

[anthonygf]

Don't forget to leave the restrictor at this membrane output.

The yellow is the waste water line.

I had my share of mixing up the lines. lol

That flush valve is useless without the restrictor in the yellow section between the T's. I know you caught this, just want to make sure op sees this also.

Sorry Mr. Gonzalez but your lines are not correct.

 

[Mr. Gonzalez]

Sorry Mr. Gonzalez but your lines are not correct.

It's crazy because it's been like this since I purchased it from brs( when marine depot went out of business). This might explain why I've had a major algae issue I been battling. Thanks again for all the help. I'll reroute everything today and update. Also recently water in our area has been more dirty lately. A year ago it was 200ppm going in now it has more than doubled. I've confirmed this with other fellow reefers in the area as well.

Yes, the entirety of the lines need to be switched.
@Mr. Gonzalez , just disconnect at the place I circled in purple and swap. Don't make any other changes to the tubing.

What about the flow restrictor? When he moves the lines he needs to keep the restrictor in it's place, and the flush valve needs to be with the restrictor.

 

[KStatefan]

From the picture i would guess that it is a check valve and the restrictor is a capillary type in the yellow line.
