Perform A Quick Flush
Before you shut off the water, connect a garden hose to the drain valve and try and flush the water heater tank a bit while the water pressure is on. To do this, open the drain valve for a few seconds and then close it again. The pressure will blow out any sediment stuck in the valve and help the tank drain faster. If quite a bit of sediment comes out, you can repeat this a couple of times.
Be sure that you’ve run your garden hose to either an exterior location or into your bucket to catch the water and sediment that will be released.

Those who have a gas-powered water heater should turn the switch to pilot. The pilot light will remain on when you do so, however, the water wont continue to be heated.
