rodi question

[sly fox]

hey,
thanks for reading...

i got an rodi unit used and a new set of cartridges...its a barracuda

-does it matter the order the cartridges are put on in?

- this may seem common sense, do i get a fitting to put on the in line there doesnt seem to be one...my assum[ption is it should connect to the tap, but i could be wrong

any help is appreciated :)

I think so, Micron, Carbon, DI

[sly fox]

thanks, which ones the micron and which the di? could you say the order i have the cartridges left to right at present and what they should be in left to right as in the pic thanks, sorry to be so dumb sounding lol

[wesheltonj]

The left one is the Micron, it goes first. The right one is the carbonit goes second. The middle one is the DI, it goes last.

[sly fox]

awesome, thanks!

with regards to the water, er how do i get it to go through the in tube <grin>

[SoLiD]

OK. I just looked at you setup and looked at mine.

Here is the the sequence for sure:

1rst - Micron Filter (white tissue paper looking on the left)

2nd - Carbon (White diamond netting outside the filter housing it's on the right)

Then (very important)

3rd - Reverse Osmosis Membrane (on top of the unit)

4th - De-Ionizing Filter (green or blue jelly beads inside the filter which is the middle one in the picture)

Follow the water tubing and you will see that this is the correct sequence.

As in a water source?

You can connect it to a garden hose, your sink, or a water supply from the washing machine. Check out BuckeyeFieldsupply's website for different connection parts.

[JimD]

Try www.buckeyefieldsupply.com (http://www.buckeyefieldsupply.com) item number BFS-242 in the accessory department. Thats one way.

[sly fox]

ah ha... awesome ... would somewhere like lowes or home depot sell them?

[SoLiD]

I have something like these two under my kitchen sink.


Easily connect your RO unit to your home's water supply with this self-piercing needle valve (standard or c-clamp style). Connects with compression fitting (included) to 1/4" tubing.
BFS-141 Self piercing needle valve - $4.00

Drain saddle with 1/4" compression fitting.
BFS-194 Drain saddle - $2.10

Yes, Lowes or home depot will have what you need. Where are your going to install this in your home. If under the sink then you need to bleed off a supply line. If in the garage near an oustisde hose bib, then you need a hose connector.

[CoryDude]

Home depot had most of the fittings you'll need. It's over in the faucet repair section. Here's how your set-up should be plumbed.

1) Unfiltered H2O should flow into the left cannister (micron filter). Then it should feed into the middle cannister (carbon block)
2) H2O from carbon block then feeds into ro membrane housing into the end w/one fitting (the side that unscrews). You'll have 2 other fittings on the other end. The middle one is the RO filter water and the one on the corner is your waste h2o. Plumb the waste h2o into a drain or something. (you'll know right away if these two lines are hooked up incorrect if you get a lot of product water and little waste water).
3) The RO filtered water than feeds into the final cannister on the right, which is your DI cartridge.
4) If DI cartridge is not marked, remember that it is upflow, so you want water entering at the bottom and working it's way up the di cartridge.
5) Finally the h2o from your di cartridge is your aquarium h2o and is ready for use.

Good luck!

You could also go on-line and get the diagrams for the unit or talk to either of our sponsors...BFS and AWI.

Self piercing needle valves are just an OK option for the supply side fitting - and yes - you can find them in a hardware store.

[sly fox]

thanks russ, whats a better option then?

[sly fox]

i did get a self piercing valve... dumb question again...does turning the valve open and shut the hole or do i need to attach a bit of hose with a valve on?
thanks

[SoLiD]

As you turn the screw on the back, it will tighten and eventually pierce the cold water PVC pipe. Once the small hole is made on the PVC, it's there for good so it would be good to make the penetration "after" the main valve. Open the valve to allow it to fill your RO/DI unit. Try to bleed out all\most of the air bubbles by moving the unit around. Also keep in mind that there will be quite a bit of waste water expelled by the "pre" RO membrane area that needs a place to be drained to. Hence the picture of the "drain saddled" in my earlier post. That will give the waste water a place to drain to. As long as the unit is making RO water, waste water will drain out of the RO membrane area. HTH

Other options include a hose bib splitter and hose bib adapter, faucet adapter.

Better yet, if you are handy, are brass fittings from the hardware store that would include a quarter throw shut off valve that ends in a 1/4" compression fitting where you'd attach the tubing. These fittings can be sweated in to your copper pipes or you can get compression fittings.

One of the problems with the self-piercing needle valves is that they start to leak, and/or won't hut off if you mess with them much. Better to shut off flow with an in-line micro ball valve as you suggest.

I looked at my RO system again last night. This is what I used instead of the "self piercing needle valve" that I thought was connected to my RO unit. The self piercing needle valve goes to the refrigerator. The feed water adapter goes between the main valve and the water hose going up to your kitchen sink.

ah something like that might be better, im plumbing illiterate, just learnt about pvc plumbing a tank, so i think cutting a copper pipe is out <grin> but that i reckon i could pull off

thanks guys...in the end i went for a hose splitter and used 2 other parts to bring it down to the 1/4 " tubing... all setup and making my first ro water :)

[sly fox]

there seems to be 3x as much coming from the waste as clean pipe...is that normal?

[tony]

yes, that is normal

some people collect it and use it to do laundry, water plants, etc . . .

[sly fox]

ah ha...ok will do that :)
