I hope you can take a look at the drawing and let me know if its ok to hook up the waste like this. The plan is to remove a section of galvanized steel pipe at both locations in red and install a PVC sanitary tee and attach with 1-1/2" Fernco Proflex couplings. The existing sink drain that will be removed is @ 14" center. The 2 new drains will be @ 22" center to get up inside the vanity. New traps not shown.
