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.
Your water heater is filled from the cold water running in a tube to the bottom of the water heater. Since heated water rises, the top element just maintains the upper part of the water as the outlet hot side is on the top. So, If you start out with good hot water - and it starts to quickly turn cooler - you know the bottom element is bad + you can put your ear up to water heater and hear which element is on. I am with the person who said to change them both. Turn off incoming water supply - let off water pressure at another faucet.
