RODI drinking water set-up

[reefbuzz]

I hope someone can help me out: I bought a new 5 stage RODI system at MACNA in DC two years ago and I'm just now hooking it up. I bought it for around $100 and it came with a 4g pressurized tank, sink faucet, and all cartridges, which is a good deal. The problem is that I lost the instructions during a recent move and now I have no idea where the instructions are, nor the name of the manufacturer (it's a generic system with no brand name).

Q: Does anyone recognize this system?

Q: Can anyone help me figure out where the drinking water outlet is?

I'm trying run a line to a sink faucet, and I'm unsure how this is accomplished when the pressurized tank only has one fitting, as you can see by the pic.

There are three outflow lines on the left (2 blue and a black) and one on the right (red, which I assume to be the effluent to the drain).

Any help would be appreciated; I'd love to hook this thing up tonight!

Hi reefbuzz
Did you test w/TDS..show me your level
i used here DI only and TDS show 011-014 is it worth for reef tank ?
my tds like this http://www.tdsmeter.com/products/dualtdsmeter.html

My TDS is 272 ppm, just checked it with a portable HM TDS pen.

You need to T off of the output from your RO cannister and run from that T to the tank and put a backflow restrictor in that line so water can only move one direction (to the storage tank) put an ON/OFF valve on the tank fitting so you can shut off flow if needed then come out of that valve to a "T" one end goes to the line from the RO unit the other to the faucet.

Hope that helps......

The T should already be on there. You'll have one line running from the tank back to the unit and depending if you want drinking water you'll hook up the blue line comong off the white cartidge on top to your sink faucet and that should work. You should have a ball valve on the blue line coming out of the DI Filter ( purple) that will run the tank water through the DI stage. The unit looks like an Ebay RO/DI unit. Do a search for RO/DI and you'll find the supplier online. Heck I'll find it for you..........http://stores.ebay.com/Filter-Direct-store.

So advice me, how many level TDS recommended ...today at 056-055 is it DI worth to use or not for reefing???
also i added backflow restrictor from John Guest at the out put.

Zoa06,

Your TDS needs to be at or near 0.

Thank you for the responses einsteins and mthedude; I'm on my way to get this e-bay pos to work.

Zoa06,

Your TDS needs to be at or near 0.

sorry late to reply
finally I have to add the RO unit and booster pump. step by step the tds level dropped into 011-09, without ro and booster pump seemed difficult

that is actually a great ro unit, i have one from the same maker. They are mainly used in hospitals but are now selling them for aquarium use.
