Shut off fuel supply. Allow to cool. Close the inlet and out let valves. Open the drain valve bottom of heater. Open the T&P to break Vacuum. Have a hose attached to dump water in a safe area.
If you are draining heater to flush don't shut off fuel supply. On a power vent heater (pvc venting) you can turn the switch off. On a conventional heater with metal flue pipe turn to the vacation setting (lowest temp setting). when your heater is refilled you can switch on or turn temp setting to original position without bleeding gas and relighting. Waiting for a sitting heater to cool will take hours. You can run hot water in house with heater off until cold. You should not have an outlet valve on a hot water heater if you do remove it. Open hot water in building to vent. Opening and old T&P will weaken the spring even more so if hot water runs through it and may cause it to fail (drip) later with water on. Some drain valves drip later with water on have a 3/4 garden hose cap with washer for valve if it leaks as opposed to replacing drain valve.

How to Keep Your Water Heater Clean?
By Andreina Urdaneta A clean water heater will heat and maintain water better and last longer. Once a year, flush your water heater, and in extreme hard water areas, at least twice a year. If you feel up to the challenge, here are some tips to help you in a basic cleaning. 1 Turn the water heater and the cold water supply to the water heater off. 2 Hook a high-quality garden hose to the drain valve, and place the other end in an area where hot water will not cause damage. 5. Open the drain valve. 6. Disconnect the cold water pipe on the top of the water heater. This step will let air into the water heater so it will drain. When the water heater is empty, close the drain. 8. Pour tile cleaner into the cold water, leave for a couple of hours and drain the detergent out of the tank. 10. Reconnect the cold water supply to the water heater. Open the cold water valve and let the water heater flush for a couple minutes. 12. Close the drain valve and open the hot water faucet nearest to the tank, and let the water heater fill. 13. When water starts to come out of that faucet, reopen the drain and let the water heater continue to rinse. After all the air is out of the water heater, turn it back on. Take care of your water heater, and it will take care of you. If you keep ignoring the task, your water heater may just leave you in the cold.
