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?

If you turn on the hot water faucet, and water comes out instead of air. If in doubt, carefully open the safety valve and see if water comes out.
Doing that with water supply on can get rid of the air pocket.
Water heater fills when water supply is on and you purge air out of hot water lines via a faucet....provided it is valved for normal service
Air pocket will form at top of WH Tank by design....helps control pressure increases due to 'swelling' of water as it is heated.
