Can someone explain the theory of a sucking drain?
If I fill the bathroom sink, tub or kitchen sink and release the stopper I get very quick drainage with some gurgling.... I also have the tiny siphon "tornado effect" and some air sucking noise toward the bottom. As soon as the basins empty there is no noise. Releasing the drain of one fixture does not cause noise or issue in other unused fixtures. And just running water into the drain (without plugging them and releasing them) there is no noise.
Is that just the sound of it going thru the strainers and traps or does this signify a pending partial clog? Should releasing a sink full of water as I describe be silent?
....What do you think?

I also agree, you drain is working as designed. Does it twirl clock-wise or counter-clockwise?

You are describing a drain that is working perfectly. It is when they do NOT suck, that you have a potential problem.

The sound you hear is caused by the vent allowing the water to flow to the greatest extent of that drain size...you are in good shape.
