There is air in the electric water heater, how to exhaust it!

The easiest way is to drain the water, and then turn on the tap to the maximum. If the water flow is stable, there will be no quick and slow changes, and there will be no squeaking, indicating that the air is clean. Because there is air, there is air blockage, which is formed by bubbles. With the acceleration of water flow, it will lead to irregular vibration and instability of water flow.
