How to Drain an Electric Water Heater
Gather Your Tools
Before you start draining your electric water heater, make sure you have the necessary tools. You’ll need a garden hose, a bucket, a pair of pliers, and a flathead screwdriver. Additionally, it’s essential to turn off the power supply to the electric water heater before you start draining it.
Switch off the Power Supply
Before you begin to drain your electric water heater, make sure you switch off the power supply. If you have an electric water heater, turn off the circuit breaker that controls the water heater. If you have a gas water heater, turn off the pilot light and the gas supply valve.
Turn Off the Water Supply
After switching off the power supply, turn off the water supply valve that connects to your electric water heater. The valve is usually located near the top of the water heater.
Open the Pressure Relief Valve
Your electric water heater has a pressure relief valve that is essential to drain it effectively. Open the valve to release the pressure inside the water heater. You can do this by pulling the lever located on the valve or by turning the valve counterclockwise.
Attach the Garden Hose
Next, attach one end of a garden hose to the drain valve of your electric water heater. The drain valve is usually located near the bottom of the water heater. Attach the other end of the garden hose to a nearby drain or outside your home.
Open the Drain Valve
After the garden hose is attached, open the drain valve to start draining your electric water heater. You can do this by turning the valve counterclockwise. Allow the water to drain completely.
Flush the Tank
Once the water heater is empty, flush the tank to remove any remaining sediment or debris. Close the drain valve and turn on the water supply valve. Open the pressure relief valve again to allow any air pockets to escape.
Turn on the Power Supply
Finally, turn on the power supply to your electric water heater. If you turned off the circuit breaker, turn it on. If you have a gas water heater, turn on the gas supply valve and reignite the pilot light.
Advantages and Disadvantages of Draining an Electric Water Heater
