RO system installation - cold water knob?

[ElBoltonero]

I live in an apartment and don't have a place to hook up an RO unit correctly; there's nowhere to put the faucet without drilling, etc. Obviously I don't want to drill any holes in the sink. I was wondering if I would be able to hook it up to my bathroom sink so that the cold water input ran directly into the RO unit instead of having a T hookup and then the output from the RO unit going directly into the cold water knob on the sink instead of its own faucet.

So, basically

cold water line → RO unit → cold water knob on the sink

instead of

cold water line ┬ cold water knob on the sink
. . . . . . . . . . |
. . . . . . . . . . └ RO unit → faucet, tub, etc.
(periods because it'll strip the spaces otherwise)

Is this possible/advisable? Thanks in advance.

Why not get a $5 adapter that just screws on to the bathroom faucet?

It's got a little lever you turn when you want to use the filter.

Ya.. shocked is on track here with this. I have been an apt dweller for years myself and have had the same problem. After using a counter top RO system for about a year, i finally got fed up and switched my tanks back to tap water

but you can get adapters for most systems

Because I'd like to install a tank with it so I don't have to worry about filling a container. I will forget it. Plus it'd be nice to have for drinking water, too.

Depending upon the filter system you've got, it may not be enjoyable as drinking water. That's something you'll want to consider.

Being in a rental, you'll also want to check with your landlord or management company before altering plumbing. That's why I suggested a faucet adapter. It's not much of a hassle to fill a container when you need it - just set a timer to go off to remind you to shut the water off. It's something you'd always want to monitor, anyway so nothing goes awry.
