Actually now that I look at it, I have 2 valves connected to the wall, for hot and cold, and each one connects directly to a braided line going up to my faucet. For my drain, it goes directly to my garbage disposal, and then into a 1" ABS pipe, then opens up into a 1.5" U trap thingy, then goes into the wall. That is why I wanted to make a T from the valve to the braided line, probably with a ball valve. Unless thats what someone already said, in which case I need to work on my reading comprehension.
