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.
Step 2. Attach a drain hose to the draining valve of the water heater, and run the hose to a floor drain or drainage area. Drain the water heater by opening the bottom drain valve, turning the valve to the left. After draining the water close the drain valve completely. Then turn the main water valve to the âonâ position. This will flush the sediment from the water heater and prevent them from clogging pipes during flushing.
