How to Flush a Water Heater

Flushing your water heater is an important part of maintaining its efficiency and lifespan. Sediment buildup inside the tank can reduce its heating capacity and even damage the element. Here's how to do it:

Safety First!

• Turn off the power to the water heater at the breaker box. (Link: https://www.wikiwhat.page/kavramlar/Turning%20Off%20Power)
• Turn off the gas supply to the water heater if it's a gas model. (Link: https://www.wikiwhat.page/kavramlar/Gas%20Supply)
• Allow the water to cool down for several hours to avoid scalding yourself.

Steps:

1. Turn Off the Cold Water Supply: Locate the cold water inlet valve on top of the water heater and turn it off. (Link: https://www.wikiwhat.page/kavramlar/Cold%20Water%20Supply)

2. Connect a Hose: Attach a garden hose to the drain valve located near the bottom of the water heater. (Link: https://www.wikiwhat.page/kavramlar/Drain%20Valve)

3. Run the Hose to a Safe Location: Run the other end of the hose to a drain, a large bucket, or outdoors to an area where the water won't cause damage.

4. Open the Drain Valve: Slowly open the drain valve. Be prepared for a rush of water, especially if the tank is full.

5. Let it Drain: Allow the tank to drain completely. This could take some time, depending on the size of the tank and the amount of sediment.

6. Flush the Tank: Once the tank is drained, briefly open the cold water inlet valve to stir up any remaining sediment. Allow the water to run clear through the hose. Repeat this process several times until the water runs clear. (Link: https://www.wikiwhat.page/kavramlar/Flushing%20Tank)

7. Close the Drain Valve: Once the water is running clear, close the drain valve tightly.

8. Refill the Tank: Open a hot water faucet somewhere in the house to allow air to escape. Slowly open the cold water inlet valve to refill the tank. (Link: https://www.wikiwhat.page/kavramlar/Refilling%20Tank)

9. Check for Leaks: Once the tank is full and water is flowing steadily from the hot water faucet, close the faucet and check for any leaks around the drain valve or other connections.

10. Restore Power/Gas: Turn the power or gas supply back on.

11. Wait & Enjoy: Allow the water heater to heat up, and then enjoy your hot water!

Frequency:

• It's generally recommended to flush your water heater once a year. If you have hard water, you may need to do it more frequently.
