Examining basin drains, I see:
1. Chrome ring that seats on basin drain hole.
2. 1-1/2" pipe with holes near the top that threads into the chrome ring.
3. Large cone shaped rubber gasket thing.
4. Large washer under cone gasket.
5. Large nut to press cone gasket.
WHAT I UNDERSTAND:
6. Water from basin goes down the drain but can also get outside of the pipe through the holes in the pipe.
7. Water from the basin overflow (if it has one) goes around the outside of the pipe and then through the holes in the pipe and down the drain.
WHAT I DON'T UNDERSTAND:
8. Since water from the basin or the overflow can get on the outside of the drain pipe via the holes in the drain pipe, the only thing stopping leaks is the large cone gasket. --- Won't water work it's way down the threads of the pipe between the cone gasket and leak? Otherwise it seems that the large nut must be tightened sufficiently to force the rubber cone gasket into the pipe threads. But can over tightening the nut crack glass, acrylic or cultured marble basins?
Thanks,
