Why Drain a Water Heater?

Draining your water heater is crucial for regular maintenance. It helps remove sediment buildup, which can reduce heating efficiency, shorten the lifespan of your tank, and even cause noisy operation. Additionally, it is necessary for repairs.

Steps to Drain a Water Heater:

1. Turn Off the Power: For electric water heaters, turn off the circuit%20breaker. For gas water heaters, turn the gas control valve to the "Pilot" or "Off" position. This is a critical safety measure.

2. Turn Off the Cold Water Supply: Locate the cold water inlet valve, usually on top of the water heater, and turn it to the "Off" position. This prevents more water from entering the tank.

3. Connect a Hose: Attach a garden hose to the drain valve located near the bottom of the water heater. Make sure the hose is securely connected.

4. Direct the Hose: Run the other end of the hose to a safe drainage area, such as a floor drain, sump pump, or outside to your yard (avoid areas where the hot water could damage plants or harm people/animals). Be mindful of the hot water temperature initially!

5. Open the Drain Valve: Carefully open the drain valve. It may be stiff initially. Allow the water to drain.

6. Open a Hot Water Faucet: Open a hot water faucet somewhere in your house. This will help break the vacuum and allow the water to drain more quickly and completely.

7. Flush the Tank (Optional): Once the tank is mostly empty, you can briefly turn the cold water supply back on for a few seconds to stir up and flush out any remaining sediment. Repeat this a couple of times until the water runs clear. Be careful to not overfill the tank if your drain is slow!

8. Close the Drain Valve: Once the tank is empty and flushed, close the drain valve tightly.

9. Close the Faucet: Turn off the hot water faucet you opened earlier.

10. Refill the Tank: Slowly turn on the cold water supply. Allow the tank to fill completely. You will hear the water running into the tank. It is important that the tank is completely full before turning the power or gas back on.

11. Bleed the Air: Open a hot water faucet to allow any trapped air to escape. Once a steady stream of water flows, close the faucet.

12. Turn On the Power/Gas: For electric heaters, turn the circuit breaker back on. For gas heaters, relight the pilot light according to the manufacturer's instructions.

13. Check for Leaks: Inspect all connections for leaks.

Important Considerations:

• Water Temperature: The water draining from the tank will be hot, especially initially. Take precautions to avoid scalding.
• Sediment: Be prepared for dirty, sediment-filled water to drain. This is normal.
• Frequency: It is generally recommended to drain your water heater at least once a year.
• Professional Help: If you are uncomfortable performing this task yourself, contact a qualified plumber.
• Old Water Heaters: Be extremely careful draining very old water heaters, as the drain valve or other components could be corroded and prone to breaking. Consider consulting with a professional.
