How do you know if your water heater is full?
Ok - so I have read never turn on the 110 heater coil in your water heater unless it has water in it - how do you know if its full or not?

when dewinterizing I first flush all the lines then turn the bypass off and open the pressure relief valve until water starts coming out the valve. Then finish by running the hot water at each location before turning on the gas or electric heating element
