Source of water for RO/DI unit

I installed my ro/di unit yesterday. I attached the unit to the valve that feeds my kitchen sink. I was not able to use the needle insert valve that came with the unit that is supposed to attach to the tube that feeds the sink faucet. This tube is braided and will not accomodate the needle insert valve.
I think that there is too much pressure going to the ro/di unit as i hear a pretty strong, constant flow of water going to the sink drain.
Is this okay? Am I wasting water or is it eventually going to stop once the unit fills?
Please see the picture.
