This is totally OT for this group -- except the group contains a lot of
obviously clever people who are professionally interested in aerodynamic
and fluid flows and pressures, pipes, valves, and the like, and maybe
someone will be entertained by the following odd bathroom sink behavio

Snipola of rest

You filled the pipe to the point it starts acting as a siphon.

I've seen my shower do it. I'm on the second level. I have one of
them 'water saver' heads so you know the flow is slow. I get about
an inch of water in the tub anyway. After several minutes, it
starts draining and stays that way.

Shouldn't make a siphon because you have a vent stack on it, right?

Yes, there is. Perhaps there's a clog somewhere. Bird nest?

At the last second turn the faucet part way off -- down to roughly 50%
of full flow, more or less -- then trim the flow until inflow rate just
equals outflow, so the water level stays just 1/4 inch or so below the
rim. Then leave it in this steady-state condition, and wait.

I think you need a hobby.

Might I suggest reading In Search of Lost Time? It has saved many
individuals who despaired of ever finding meaning in life.

(I recommend the new "Penguin Proust" translation.)
