    i have a 2 inch pvc 90 stubbed out under the sink....i was planning to install a 2 inch trap then use a 2 in to 1,5 reducer to connect to the tail piece

    or would it be better to put an a 2 inch adapter at the 90 and use a 2 to 1.5 inch lock nut and step it down and use 1.5 for everything

    which would be the better job?

    drain

    Neither way is necessarily "better" and both are equally adequate. Because of the long term benefits, I would use the reducer on the 2" and 1 1/2" tubing for the rest of the drain installation.
