I have a leak at the union of the drain trap to the pipe from the wall. I've tried using one washer, two washers, teflon tape. No matter what I try I still have a leak. I almost got new washers but that doesn't make sense as the ones I have are in good shape. Now I'm thinking of getting a different trap but I don't see what difference it would make. I'm frustrated. And yes I'm a plumbers worse nightmare an amateur diy'er.
