So, I have an Express Water 50 GPD RO system installed under my kitchen sink.
When I began my saltwater journey with a 32 gallon Biocube I realized I could probably just add a DI cartridge to my existing system and have a dual purpose unit. I don't make RODI water for the aquarium automatically. I manually direct water through the DI and into 5 gallon jugs a few times a week and this works fine for me as I usually store them and make 30 gallons of saltwater at a time.
However, I recently added a 3 probe TDS meter and pressure gauge and realized that 1) my incoming pressure is around 50-55 psi and my TDS is 450 (incoming) 30 (post RO) and 2 (post DI). I am pretty sure my DI was 0 initially and I have only made about 50 gallons of RODI water.
I have the DI cartridge connected to the yellow line to the pressurized reservoir tank with a ball valve on the DI side to turn it on and off. When this valve is closed to the DI cartridge the RO water is stored into the tank and when needed it feeds into a carbon filter and then an Alk filter and out a drinking water tap at the sink. When it is open it pushes water from the tank initially, out the DI and then once the tank is depleted, from the RO membrane directly to the DI (Noticeable flow decrease)
Im not sure if Im getting any backflow from the carbon and alk at the end of the chain or bypass to the tank though.
I am looking at adding the aquatic life RO buddy booster pump to my system to improve the incoming pressure and hopefully increase efficiency. All the diagrams I have seen show it used for a single purpose RODI system.
Are there any gotchas to installing this with my setup? For instance, should I install any check valves anywhere? And could I just swap to a higher production rated RO membrane (100gpd to match the max of the pump unit). And would this speed my production when I do go to make DI water after the initial tank water empties.
Thanks!
