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 to power OFF to the water heater at the circuit breaker (electric heater ) or main gas line (gas heater). 2. Fasten a length of garden hose to the drain valve at the bottom of the heater. Put the other end of the garden hose. in the nearest floor drain or snake it outside the home. 3. Close the shut off valve at the cold water inlet line. 4. Open the temperature and pressure relief valve at the top of the heater. Now open the drain valve and allow the. water to drain. You will probably notice some small white particles (called scale or sediment) during the early. stages of the flow. 5. When the water stops, close the drain valve and remove the hose. Also close the temperature and pressure relief. valve at the top of the heater.
