Hello Folks-- I am installing a new fiberglas shower stall (Lasco). The drain pipe, 2" ABS, is slightly mis-aligned with the Oatey "NO-CALK" drain, so that the rubber gasket must deform further on one side in order to seal the opening. The drain pipe has no flexibility for adjustment (it's all used up, already!) I am concerned that I will never be able to make a good connection. Has anyone dealt with this problem successfully? Thanks.
