RO/DI really needed for Fish + Dead Live rock system?

The flow restrictor will be inside the waste line coming from the RO (top chamber). Try disconnecting the waste line from the RO and see if you get flow.

Caution - if it working right you'll get a LOT of flow out of the waste of the RO with no restrictor so watch out for a mess...

Yea I got the RO inside a big plastic tub. Had it leak on the floor last night so learned the hard way...okay here I go, lol, brb

 

[john suh]

I disconnected the yellow waste line from the RO and water flowed out freely. Yah I saw a mechanism inside the tube, with a long tail black end so assume that the restrictor valve?

 

[bang guy]

Right, that's the restrictor. It creates backpressure to force water through the RO membrane. It is required for the RO to work properly. In your case I believe it may be defective and is not allowing any water through.

One more thing... are you in a cold area of the country? What is the temperature of your tap water?

 

[john suh]

Actually now that I have pulled it apart and put it back together and turned the water on I see waste water flowing out the yellow line so that's a huge step from where I was so maybe it was just in an awkward position. Now I'll just wait awhile to see if my good DI water starts filling in the bucket

Supposedly 1 gallon per hour which is fine for my size tank.

Thanks man!, I am leaps and bounds ahead of where I was last night,

First noticeable benefit I see with RODI water is the salt mixture dissolves very quickly. Just a couple stirs and not a single trace of salt granule. My original tap water with TDS measurement of 200 took forever to dissolve.

 

[bang guy]

It makes really good coffee too.

The flow restrictor will be in the yellow waste water line. It should be in the line close to the flush valve. You should find a place where the line has a "joint". This is where the capillary restrictor is located. You'll have to pull the line apart and then pull the restrictor out. If the restrictor has a tube attached (tail), that end goes towards the drain. If it doesn't, the long end (below the flange) goes to the drain, and the short end towards the RO housing. Water flow in a 24 GPD system is only 1 gallon per hour... max. There will be very little flow, even when it's at peak performance. This doesn't explain not flowing at all. If it works with the RO membrane removed, make sure you are installing it in the correct position. The end with double O-rings goes in first, and the rubber skirt-type seal goes towards the cap side of the housing. Also make sure everything is connected in the right order and in the correct ports. Water source line to "in" port on sediment cartridge, "out" port on sediment cartridge to "in" port on charcoal cartridge, "out" port of charcoal cartridge to the port on the cap of RO housing, the "center" port on end of RO housing to "in" port on DI cartridge. Again, the port on the edge of RO housing goes to your flush and restrictor valves.
