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.
Prior to dissolving water heater sediment, you need to drain the unit. When water is heated, naturally occurring minerals separate and settle at the bottom of a water heater. Over time, the sediment builds up, reducing the efficiency of the unit in heating and storing water and potentially damaging the water heater.. Remove the funnel and reattach the water line. Turn off the burner. Open the cold-water valve and the drain valve, which should still be attached to the hose, simultaneously and drain the solution out of your water heater.
