Advice on RO system

[jjbunn]

The previous owners of my house installed a RO2127 Reverse Osmosis system under the kitchen sink, which is very handy. This system has a ROM-16C membrane, P5 pre-filter cartridge and D20 post-polishing cartridge: a very basic setup from what I understand. The system also includes a pressurized storage tank, and supplies 15 gallons per day.

Right now I am looking at replacing all the cartridges, as I expect they are way past their prime. But I'm wondering if I should instead replace the whole system?

TDS from the city supply is around 400ppm (gasp!). What's coming out of the RO2127 currently is 300ppm.

Comments/advice most welcome!

Air water and ice in flordia. Describe your unit. They will either get you add on.pieces for you to make "reef keeping" water or s whole new unit. $$$ lol.

Yeah, that system probably isn't really worth dealing with. You can get some decent systems to start with on Amazon for not too much money.

Very happy with the brs system, especially after adding a 2nd ro membrane.

The beauty of most any RO/DI system is that you can always add on if needed. I got my system on Amazon and have since added 3 DI stages. Very simple setup and not too expensive. Now I am getting perfect 0 TDS water from a well.
