I used sink plungers in toilets pretty much my whole life until i scrolled across a similar diagram one day and discovered the truth.

So weird. It always seems to pump air through the overflow and do no good. By the time you figure out how to plug the overflow, you might as well have taken off the trap and emptied it in the trash …… especially with PVC traps where it all just comes apart without tools
Many sinks do not have overflow drains.
I just put my hand over the hole, takes two seconds. And I don’t have to clear out under the sink and get a bucket. (And it’s only very rarely necessary)
