I am installing a new sink in a bathroom. The drain in the middle of the sink has a straight 1-1/4in OD flanged tail piece that is supposed to go into the P-trap that leads into the waste line. But this tail piece is a little bit too short. So I need a longer tail piece. I looked long and hard at Home Depot and Lowes. They have lots of 1-1/2 in OD flanged tail pieces but no 1-1/4 in ones. Is this a non standard size? Can anyone suggest where else I might try to look for one? thank you.....
