Rodi ?

[ShawnSaucier]

I'm needing new filters for my RODI, can I go micron, carbon, DI+ DI for my 4 chambers? Or does that not work?

 

[Randy Holmes-Farley]

Sure, that's what I use.

Of course, the RO must be between the carbon and the first DI.

 

[ShawnSaucier]

I'm not sure if that is how it is set up. When I purchased it, filters were micron, carbon, carbon, DI. And there are two RO units.. It is the BRS 150gph

 

[Randy Holmes-Farley]

OK, the order is important. You would not want a DI before the RO units.

The 2 ro should be ontop. Then it should be the carbon block then the sediment and then the di. I believe it's the carbon first what ever one has the furry looking outside like a paint roller

The original order is sediment, carbon, carbon, RO, RO then DI.
Sounds like you want to convert the second carbon canister into a dual DI which is easy enough to do with a few fittings and a little time.
If you do that, purchase a better 0.5, 0.6 or 1.0 micron sediment filter and carbon block as the 5 micron versions they come with are pretty coarse and you are eliminating the sacrificial carbon block.
You will need to replumb the second carbon canister by removing the nylon nipple between it and the first carbon lid so now the first carbon OUT line leads up to the RO membrane IN, then through the membranes and back down to the DI which you have replumbed and into the final DI. It is actually easier than it sounds.
