What would cause air in water heater / lines?
Suburban SW6DE. Seems to work as it should. Serviced, new anode, electric element. If I leave it turned off, run water, all is well. Turn on to have hot water, I get air through any faucet in spurt...

A possible explanation is related to the fact that air dissolves in water. Dissolved oxygen is water is what makes it possible for fish to breathe. As water is heated the solubility of the air becomes less and the air comes out of solution and creates air bubbles. As the hot water is used new cold water with dissolved air enters the heater becoming a source for more air bubbles.
