In a disaster, your water heater could hold the last drinking water you'll get for awhile. The cheap plastic drain valve that comes on most water heaters, and even the slightly better faucet-type brass valve that comes with some, can easily clog with sediment buildup. Replacing it with a straight-path ball valve will ensure that you can get the water out if you need it, and that if sediment does clog it, you can easily unclog it with a long screwdriver.
