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.
Depending on which water heater drain pump you use you can empty a 50 gallon water heater tank within 2-1/2 to 10 minutes instead of waiting for the water heater to drain by gravity. Step 5. Open the hot water side of your kitchen faucet (or the hot side of any faucet close to your water heater). This will allow air to flow back to the water heater stopping any vacuum in the water heater that will keep the water from flowing out of the drain. Step 6.
