Turn off the Water Supply

Connect a hose to the drain valve located close to the thermostat, but don’t open the valve yet. Turn off the cold-water supply that feeds the water-heater.
Drain the Hot Water
Inside your house, open up one of the hot-water faucets in one of your sinks or tubs. This will prevent a vacuum from forming in the lines.

Once the water stops flowing out of the far end of the hose, turn the water supply back on. This will flush out any remaining sediment left behind in the heater. Once the water runs clear from the end of the hose, close the DRAIN valve. Don’t forget to turn the hot-water faucet inside your house back off.
