Where else can I plumb a feed line for my RODI?

So while making water all day yesterday (I have a slow RODI, only 25gpd) my faucet adapter blew off, broke a few glasses in my sink, and managed to strip out the female threads on my faucet. Now it cant hold it together to maintain pressure, putting me without a RODI, and of course I have no top off water! Im going to grab some 2.5 gal jugs of distilled to hold me over, but what can I do about the faucet adapter? Anyone know how much it costs to plumb a line in under the sink? Any other options? Thanks

Audi, you can buy a self-tapping saddle valve for a couple bucks at HD or Lowes.  It simply screws onto a copper pipe and then you twist in the valve part and you now have a water source.  The fitting on your RO/DI unit simply screws onto the valve.

Wow awesome, thanks for the suggestions! I wish I had posted this when I first got my unit, I had a hell of a time finding a fitting for it! Ill run down to HD later in the week and look around.
 
i have a few adapters on my washing machine's source fixture. it is basically a Y adapter for a hose and then a brass nipple that takes the hose threads to the size of the RODI.
 
There are adapters that go onto the shutoff valve under your sink. They are a simple compression tee 3/8 x 3/8 x 1/4. That is where mine ties in. That way there is not modification to the lines. I have some at work if you are interested.
 
make sure you tap into the cold line not the hot and if you need water for t.o. in the mean time, I am located in forked river.
 
Thanks for all the input guys, its good to know I have a few choices. It seems like the smaller copper pipes are hard to find in my 1 bdr apt. Under either sink I have a shut off valve and flexible braided steel hosing. Will that be suitable for a tap-in type fitting as previously mentioned? Im pretty sure it couldnt get a good seal on a flexible line as opposed to the solid copper. Im a total new noob to plumbing, only recently got out from the parents house :)

Thanks alot chad, Im up in Hackensack, like an hour and a half away. I really appreciate the offer though. Its nice to see the generosity of the local sites, much more personal. Besides, a 2.5 gal jug of distilled is like 3 bucks.

You can not mount a saddle valve on a stainless steel flex line. These are made to tap into a copper pipe. You’ve got to have a half inch of copper somewhere under that sink. As far as installing this little valve,they come with a little rubber gasket seal and again, are self tapping. Once you screw the two screws to mount the valve, you then use a wrench to tap into the copper pipe. This is real simple stuff. The only tools needed are a screw driver and a wrench.

Just go to HD/Lowes and ask the plumbing guy for a saddle valve for an RO unit (or ice maker). My guess is about $5.00 for this valve.

Now, after saying all that….since you are in an apartment, you might want to take a less invasive approach. Here you could remove that flex line from the cold side and put in either a threaded “Y” connection with the proper fittings OR a second valve with the correct fitting for the RO unit. Will cost a few more bucks, but when you move out, just unscrew this and remove it and no one will know otherwise.
 
Yeah I think thats what Ill try. MB sent me a pic of a valved fitting and it should work well. I live down the block from the Home Depot, so Ill head over there one night this week.
