Hello. I'm at a loss right now. I have a 1-1/2" brass tailpiece with a wye and am trying to hook it up to the strainer. However, the 1-1/2" rubber washer made for the brass sits half inside the bottom of Strainer and half around the tailpiece and it leaks once I tighten. Do they make like 1-5/8" or 1-3/4" OD washers. This is the last thing to finishing up my sink and have been going crazy trying to fix this and save money. Any ideas? Thanks.
