I'm trying to connect this drain assembly on my bathroom sink.
But when I connect to the sink it drips. I tighten the top nut(arrow) with a channel lock, but it still drips. Steps I took:
- I put plumber's putty on the top
- squeeze the top into drain hole.
- attach the drain pipe to the top
- turn the top nut tigh.
- attach p-trap to drain pipe.
Am i doing something wrong, sometimes I hear a snapping sound and it seems that the drain pipe has loosen. Should I use Teflon tape?
