I wondered why my kitchen's S-trap has never smelled or gurgled.
Tonight I filled my sink with hot water:
and opened the plug to let it drain.
Then I waited 10 minutes and took the visible and thermal images below:
This shows me no siphon is happening with my sink. I think there are two reasons I am getting lucky: 1) The sink basket is pretty constrained and the water runs down quite slowly. Here is my strainer.
And the other is this drain meets the horizontal drain in my basement perhaps 14" below the floor
