flushing vs draining

Question- i have a water heater about 2 years old and i am just starting to hear that "popping" sound. From what i have read, it is due ot sediment inside the heater. I have read about flushing and draining- in my case, what would be suggested. thanks.

a1a, Welcome to the DIY Forums.
Do both. If you just drain, some sediment will leave the tank but will still leave a lot inside.
Turn off power for electric heaters, set control to pilot for gas. Turn off water supply. Open a hot water faucet near the heater. Hook up a hose to the drain valve. Open the drain valve and let it6 drain. Turn on the water supply valve and let run about 3 to 5 minutes. Turn off water and let drain. Watch the water leaving the hose. If there is still sediment coming out, repeat this step. If not, close drain and refill tank. Close the faucet you opened and return power to the unit. This should be done at least once a year. Good luck.
