How to Drain an Electric Water Heater?
1- Turn Off Power
Before you do anything else, you must first turn off the power to the water heater. This is done at the electrical panel by disabling the circuit breaker or fuse powering the water heater.

2- Turn Off Water
Next, turn off the water supply to the water heater. You should find a water shut-off valve at or near the cold water inlet pipe at the top of the tank. Turn the valve clockwise to shut it off.
If you cannot find a local shut-off valve, turn off the water supply to the house at the main valve.
3-Ready the Drain
The drain cock at the bottom of the water heater tank is a silver or brass colored valve with a threaded end. This is where water comes out of the water heater and you need somewhere for the water to go as you drain the tank.
You can either place a bucket under the drain valve or attach a garden hose to the threaded end of the valve. Run the garden hose to a floor drain if you use that option.
4-Open the Pressure Relief Valve
You will then need to locate the water heater's temperature and pressure (T&P) valve so you can relieve pressure from the tank. It is either on the side or the top of the water heater. Look for a valve that has a tube leading downward.
Flip the lever on the T&P valve into an up position to open it.
5-Drain the Water
With all safety precautions taken, it is time to drain water from the tank. Some drain valves have a handle. Others have a short handle-less stem with a slot for a flat blade screwdriver.
6-Close the Valve
Once the draining is complete, close the T&P valve by flipping the lever down and close the drain valve by turning it clockwise. Empty the bucket or remove the hose.
7-Turn on Water Supply and Power
With the tank drained, you can perform any maintenance required. When the repair is complete, or if this was just a maintenance flush, turn the power and water supply to the water heater back on.
