1 Answer from this member: Unless you are very experienced on replacing water heater elements, Yes, I strongly recommend draining the tank first. Otherwise, it could cause a lot of damage. To drain the tank, be sure to turn the breaker and supply water valve off and open any hot water tap in the house.
With Gas all you have to to do is turn it off nd let the water drain out. with an electric heater you need to first make sure that the circuit is turned off. Go to the breaker panel and make sure that you have thepower turned off to the unit. You then need to make sure that all the water is turned off to the home. At that point you will get a bucket and drain the heater. Make sure all of the old water is out of the heater.
