I just replaced my bathroom sink and added new faucet which came with drain kit. I can’t get the circled connector to stop leaking and it really feels like the new drain pipe is just too small to have a good seal. Using the washer on the pipe and then hand tightening but can’t get water to stop bubbling out the top. Thoughts?
Added 2/26 - pic showing gap between p trap and drain tailpiece. Seems like it might need some overlap instead of just different gasket. This is the only config possible with existing equipment.
