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.
Turn off the power to the water heater in your electrical panel, and then check the power wires at the water heater with a multimeter to make sure that the power is off. Drain the water out of the tank using a common garden hose attached to the drain valve at the bottom of the water heater near the floor. Remove the elements from the water heater. You can clean them with a mixture of vinegar and water, or sodium carbonate and water.
