Is this yeast that has been sitting around for years? If not, they are most likely fermenting unless you added them to hot water. 1/2 teaspoon of dry yeast is not a lot and it might take awhile to start. Remember, the yeast generated CO2 has to saturate the fermenter water before it starts displacing the air in the bottle and hose line. When you shake the bottle, it causes dissolved co2 to come out of solution in a burst, but it creates room for newly created co2 to be absorbed by the water.

Baking soda is not needed for fermentation.

I would install a check valve just to prevent all kinds of problems with siphoning.
