It is also the same wall that my washer is hooked up to in my basement. If you look at these 2 pics, it will show better.
I plan on moving the existing washer drain to the upper diagonal pipe with a trap (which has a plug on it right now in the picture). On the other side of this wall is my den. 2 questions:
1)When hooking up my sink drain, can I go trap to trap, or should I remove the trap from my sink and just run directly to the basement trap?
2) how can I utilize my washer supply lines to supply water to the sink? I was thinking of buying a hose T of some sort, so I could split the hot and cold for the washer and sink. I would get long braided supply line, like the washer. Again, this is only a temp kitchen (2 months tops).
