This will remove the sediment that has accumulated at the bottom of the tank. Getting rid of this sentiment extends the lifespan of your water heater and improves its efficiency. It also helps your water heat water faster.
Turn the Water Heater Off
If you have an electric water heater, flips its switch in your home’s breaker box. If it’s a gas water heater, turn the thermostat on it to “Pilot.”
Turn Off the Cold Water Supply
There’s a cold water valve by your water heater that you need to turn off. It is usually near the top of the water heater. By turning this off, water won’t flow into the tank while you’re flushing it. Before continuing, wait an hour or so for the water in the tank to cool down.
Turn on Hot Water
Turn on the hot water in a sink or tub and leave it on through the entire process of flushing the tank. This helps the tank drain faster and prevents a vacuum from forming in the water lines.
Connect a Garden Hose
Connect a garden hose to the spigot at the bottom of the tank. You should place the other end of the hose outside.
Drain and Flush the Tank
Finish Things Up
You can now turn off the water in the tub or sink. Turn off the drain valve, disconnect the hose and turn the cold water spigot on. You can now restart your water heater.
