I was just thinking too...I used my last RO unit for year with it attached to the faucet. Seems to me then that I should be able to tap into that grey line that goes up to the sink and still have enough pressure. That can't be less pressure than I had through the actual faucet right? Shouldn't it actually be more since there is less distance?
If I did tap into that line, what fittings would I use?
I have figure out the drain and its actually going to be quite simple and easy.

1. Yes, I don't know how your condo is set up so if you want to tap in before the cold water shut off, you'll have to find out where the main shutoff to that line is. Check some of the other rooms in your condo that also have plumbing, sinks, toilets, laundry etc. You might find a main shutoff there somewhere, otherwise....
2. Yes, you can tap into the grey line, I was just thinking out loud there. I don't know what your RO/DI specs are for water pressure for a 100 gpd membrane. The smaller line may actually give you more since it's kind of a venturi effect going from the large supply line to the sink supply. But it's like any plumbing, every valve and fitting is going to create a slight pressure loss. I'm not a plumber though so I can't say for sure what that may be.
3. Any home/building supply store will have a bunch of these little grey sink adapter lines (as well as rigid stainless plated copper ones) laying around in a bin somewhere. Grab one and start hunting around in the other bins for appropriate fittings, they shouldn't be far away. Take your red RO/DI line with you if you can so you can test fit the fittings in the store or at least show the staff what you're trying to do.
4. Yep, the drain should be pretty straightforward, not a lot of pressure involved, just need to make sure you've got an adequate seal.
