SOURCE: Water leakage at lower heater
I believe your water heater could have a 6 yr warranty. If its leaking then you should be able to get it replaced for free. Call the place you pruchased it at and see what their procedure is for returning it. Most places just allow you to bring it back and they will give you a new one. To uninstall, first shut OFF the breakers to the power or shut off the gas. Then shut OFF the valve to the water supply line and if there is a shutoff valve on the other water line line coming out of the heater, shut it off also. Once the water valves are shut off, remove the two water lines from the top of the unit. On the bottom of the unit you will notice a water faucet valve. Attach a garden hose to the valve and run the hose outside on the ground. Open the water valve and your heater will drain through the hose to outside on the ground. Then, with the power OFF, unattach the wires from the junction box or wherever they are attached or if it is a plug, then unplug it. If it is a gas model, unattached the gas line AFTER the gas is truned OFF. Once the water has fully drained from the tank then it should be ready to be moved. Reinstall the new tank in the same manner in reverse.
