If you’re experiencing issues with your water heater, it may be time to drain it. Draining your water heater can help remove sediment buildup, improve efficiency, and prolong the lifespan of your appliance. However, if you’re not familiar with how to drain a water heater, it can seem daunting. In this blog post, we’ll provide you with a step-by-step guide on the process of draining a water heater.

Step 1: Turn off the power supply

Before you begin, make sure to turn off the power supply to your water heater. If you have an electric water heater, turn off the circuit breaker. If you have a gas water heater, turn off the gas supply valve.

Step 2: Turn off the water supply

Locate the water supply valve and turn it off. This valve is usually located near the top of the water heater and may be labeled “cold” or “inlet.”

Step 3: Connect a hose to the drain valve

Locate the drain valve at the bottom of the water heater. Connect a garden hose to the valve and run the other end of the hose to a floor drain or outside.

Step 4: Open the drain valve

Open the drain valve by turning it counterclockwise. This will allow the water to flow out of the tank and through the hose.

Step 5: Flush the tank

Once the water has drained out of the tank, turn on the water supply valve. This will help flush out any remaining sediment or debris. Let the water run through the tank and out the hose for a few minutes.

Step 6: Close the drain valve

Once the water runs clear, turn off the water supply valve and close the drain valve by turning it clockwise.

Step 7: Refill the tank

Remove the hose from the drain valve and close the pressure relief valve. Turn on the water supply valve and allow the tank to fill up. Once the tank is full, turn on the power supply to your water heater.
