USA Expansion Tank Issues

[Gmb2003]

Every time I flush my toilets, I hear a popping sound from my expansion tank. I have drained the water from my electric hot water heater. I have shut off all the water going into the house, cut my faucets on to drain them to get any air out my lines.

Im going nuts trying to figure this out.

Help me please
