Ro/DI System suggestion?

[allendehl]

Hello folks,

Shopping for a RO/DI system. I live in Miami, FL where they use chloramine in the water.
I contacted BRS and they suggest their Stage 5 systems because of it. I am also looking at Spectrapure.

First question, do I really need a Stage 5?

Second, off these two which one would you pick?

Thanks!

As to if you need 4 or 5 or whatever thats almost an impossible question to answer positively but a lot of that decision I believe is based on your tap water TDS..
If its low then you "shouldn't" need as much filtration to protect the RO membrane..

I'd suggest the BRS system
or one from airwaterice I think both are right around the same price (once you add a dual TDS meter and pressure gauge to the airwaterice system)... and their catalytic carbon upgrade..

In general all the systems will perform identically as there is nothing proprietary about any of them and its all just canisters and standardized filters..
So really price is king..

Not sure why you would need the dual DI spectrapure system based on what you have said so far..

Just a little more info just because...

Here is whats nice to have
1-ASOV valve if you intend to leave it on all the time.. and by on I mean having a constant supply of water to it.. So that it will shut off the waste water when you close the valve on the "good" water line..
2-Pressure gauge to let you know what your supply pressure is so that you can either adjust your household pressure (water pressure regulators are in most houses) or purchase a booster pump if needed.. In general you want a min of like 50 PSI or performance really starts to suffer..
3-Dual or triple TDS meter so that you can see TDS at various stages through the system to monitor performance/filter life..

All 3 of those are well worth the extra cost..

and all of the systems you are looking at are standardized but make sure that any water filter uses standardized filters (2.5" x 10") and not company specific special filters as the replacement cost over time is usually FAR less as there is competition between companies out there versus needing to go with a specialized filter that only that manufacturer makes..

Then if you want drinking water too.. Thats another choice you can make..That requires a Tee right after the RO membrane and a check valve and pressure tank to store water in so that you aren't waiting drip by drip to fill up your glass..
Adding on drinking water can be done at any time along with everything above.. All these systems are modular and easily upgradeable at any time..

Chloromines eat up the media very quick. BRS 5 stage at least

You are something else! I went ahead and ordered the BRS Stage 5 yesterday. My mixing station is outside so I'll either have a little awning against the wall to cover the unit or make it so I can bring it back in after I fill up what I need. Space constrains:hmm2:
