When you open the faucet, that's the path of least resistance so the water will come rushing back, pushing out the air

Its drawing the water from the kitchen faucet because that is the closest fixture to the leak more than likely


The spout has an o-ring so that it can swivel left or right and if that is bad the water in the spout will leak out leaving only air in the spout. When you turn on the water it will sputter etc.
I have replaced several faucets because of this. Not sure if it is the problem but is easy to eliminate. There is no pressure in the spout between the valve and the aerator unless the valve is on.
