RO Plumbing under sink

This might be a dumb question, but I'm confused. I looked at several other RO plumbing threads and there's no mention...

I've been using an RO/Di for a while rigged into my washer plumbing. I want to move it under my bathroom sink. I've seen the tees and splitters with valves that allow you to split the RO off from the faucet undersink. They all show a 1/4" adapter for the RO intake.

1/4" is the same thing as icemaker line, correct? That's what my RO has for everything but the intake. The intake has a connection like my washer, which I can easily cut off - but I KNOW that the tubing there is larger than a quarter of an inch.

What am I missing? Do I need to replace this entire tube (from the split to the RO) with the smaller tubing?

To get this out of the way - anything that punctures a pipe is out of the question. The wife will revoke my plumbing priveleges immediately...
 
So you have something like 1/2" or 3/4" "garden hose" on the in side of your RO/DI unit??
And is that just because someone got some fittings to go from 1/4" tubing to the garden hose setup?

Just get a "T" and tap into the cold water line under the sink. Then get whatever fittings you need to adapt to that "T"..

Thats the fun of plumbing.. 500 different adapters/fittings,etc.. and its up to what you can find to hook it up..

The goal is just to connect to the faucet cold line and have it not leak.. Thats it.. How you do it is really up to what you can/cannot find at the hardware store.
 
Your looking for a threaded valve is my guess most ro systems use compression fitting which have a larger tubeand different sized nuts and threads.... trust me hd and lows both carry the parts u need go make the over paid master plumber do his job :)
