I'm not sure which water feed attachment I need in order to hook up a RO/DI system into my sink in my laundry room.

There are 2 different Feed Water Devices:
Regular: 1 x 1/4" Needle Valve

or Option A: 1 x Chrome 3/4" Tee with 1/4" Ball Valve
http://61.220.188.82/items/Pic/22-01-P1-1.jpg

Does anyone have any idea which attachment is used for which application? Is there an option to hook up under the sink (to the cold water line)? Alternatively, is there an option to hook up directly to the end of the faucet (with a "pass-through)?

PLEASE HELP!

1 is a saddle valve. I would try to avoid those.

2 is likely your best option, but you still might need a trip or two to the home center if something needs something to fit somewhere:)

Option 2 for sure, That is how i use mine now, the valve is very handy.

I tried that clamp on needle valve and it leaked.

Thanks for your replies.

Regarding option 2, where does that go? Does it hook up to the cold water line under the sink? Or to the end of the faucet?

Cold water line under the sink.
