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.
Drain Your Water Heater. Connect a garden hose to the drain valve. Place the other end of the hose in a drain or outside (you could also use buckets). Shut off the cold-water supply to the water heater, and open a hot-water faucet and the drain valve.While the water heater is draining, read the installation instructions that came with your water heater.Disconnect the vent pipe from the draft hood.urn the main gas supply valve off. Also, turn the gas control knob on the old water heater off. Open a hot-water faucet, and let the hot water run until cool. Allow the old water heater and vent pipe to cool.
