Step-by-Step Instructions
1. Gather Your Tools
You will need the following tools for this task:
- Adjustable wrench
- Garden hose
- Bucket or drain pan
- Plumber’s tape (optional)
2. Connect the Hose
Locate the drain valve at the bottom of the water heater tank. Attach the garden hose to the drain valve by hand-tightening it.
3. Open the Drain Valve
Using the adjustable wrench, slowly open the drain valve. Be careful not to overtighten, as you may damage the valve.
4. Drain the Water
Allow the water to drain into the bucket or drain pan. The draining process may take some time, depending on the size of the tank.
5. Flush the Tank (Optional)
Once the water has drained, you can flush the tank to remove any remaining sediment or debris. To do this, turn on the water supply and let it flow through the drain valve for a few minutes.
6. Close the Drain Valve
When the tank is empty, close the drain valve by hand-tightening it securely.
7. Disconnect the Hose
Remove the garden hose from the drain valve.
How to Drain an Electric Hot Water Heater with a Pressure Relief Valve

Locate the pressure relief valve on top of the water heater. Lift the lever or pull the handle to open the valve.
3. Drain the Water
Allow the water to drain into the bucket or drain pan. This process may take some time.
4. Close the Pressure Relief Valve
Once the tank is empty, close the pressure relief valve by pushing down on the lever or handle.
How to Drain an Electric Hot Water Heater with a Dip Tube
Some electric hot water heaters have a dip tube that extends from the top of the tank to the bottom. This tube can be used to drain the water.
1. Turn Off the Power and Water Supply
Follow the safety precautions outlined earlier.
2. Disconnect the Dip Tube
Locate the dip tube at the top of the water heater. Disconnect it by unscrewing the nut holding it in place.
