The best fix

Please help,

I am pretty handy and have done this plenty of times, but as I have found in the past, there is always a problem... I am installing a new sink in my friends 1/2 bathroom. When I took the old (very old) sink out I noticed the threads on the 1 1/2" nipple coming from the wall were rusted and cracked. I thought the easiest fix was to buy a rubber Quick Plumb 1 1/2 '' to 1 1/4'' to hook to the old nipple and to the new plastic 1 1/4' trap. Since then I have been to the home improvement twice with different opinions on how to do the job. It seems that I am having so many problems with the 1 1/4" side of the plumbing. Is the plastic trap a bad idea? Should I go with a PVC trap and do they sell a PVC 1 1/4" that can be connected to the plastic 1 1/4" sink pipe (tailpiece)??

Thanks for the help.

PVC traps are just fine, and yes, they sell 1.25" PVC drain assembly parts. PVC compression nut drain assemblies are made to just hand-tighten. Install the beveled washers with the bevel toward the pipe and the flat side toward the nut.
Good Luck!
