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.
