Building RO unit.
I just moved into a new house and the previous owner bought two 20" big blue filter housings, but never got them installed. I am not interested in a wohle house filter setup, but have always wanted an RO unit. I was wondering if i could use them instead of purchasing a new kit from BRS. Is a 25-1 micron sediment with a single carbon filter, such as the CBC20-BB be enough or do i need to purchase another big blue for a second carbon filter?
Everything else looks straight forward and the house has 80 psi pressure. |

No need for a second one, just the RO unit + a DI.

I would buy a third 20" for the DI resin and buy an RO canister. That would give you a nice 4 stage ro/di system. You'd need a few other small components, pressure gauge, back flush, tds meter.

If im reading this correctly your going to run a sediment filter and carbon filter and thats it? It doesnt sound like you have an RO membrane or DI cartridge. Most of the 4 stage systems run a sediment filter, a carbon filter, RO Membrane and then the DI. Unless I am missing something.
