The importance of your water heater cannot be overstated, as it serves a vital role in supplying hot water for a range of household tasks, including showers and dishwashing. Unfortunately, sediment accumulation in the tank can diminish its efficiency and potentially cause harm over time. Flushing the water heater, and other maintenance tasks, is crucial to guarantee peak performance and enhance its longevity. In this blog, we will discuss the top five tips for appropriately flushing your water heater.

1. Turn Off the Heater and Gas Supply

Before starting the flushing process, ensure the water heater is turned off. For electric water heaters, switch off the circuit breaker, and for gas water heaters, turn the thermostat to “off”. Additionally, shut off the gas supply to the heater. This step is crucial for your safety and prevents the heating elements from functioning during the flushing procedure.

2. Allow the Water to Cool

Flushing a hot water heater can be dangerous if the water inside is scalding. To avoid burns and injuries, allow the water in the heater to cool down before starting the flushing process. This may take a few hours, so plan accordingly. Safety should always be a top priority when performing any maintenance on your water heater.

3. Connect a Hose and Drain the Tank

Locate the drain valve, which can be found at the bottom of the water heater. After you do that, connect a garden hose to it. Ensure the other end of the hose is positioned where the hot water can safely drain without causing damage. Open the pressure relief valve on top of the tank to allow air to enter, facilitating a smooth flow of water. Once connected, open the drain valve and let the water flow out until it runs clear. This process helps eliminate sediment and debris that may have settled at the bottom of the tank.

4. Turn on a Hot Water Faucet

Next, turn on a hot water faucet closest to your water heater and keep it turned on until the entire flushing process is complete. This will help relieve pressure and also help your tank drain faster. 

5. Close the Drain Valve and Refill the Tank 

After you’ve finished flushing the tank, and have confirmed the water is running clear, you can close the drain valve, remove the garden hose, and fill the tank. It’s important at this point that you ensure the cold water supply valve is turned on. Once it is, the tank should begin to refill. Keep your faucet turned on for the time being to allow for the release of any trapped air. When the faucet is running at full pressure with a smooth water flow, you can turn it off. This is a good indication that the tank is full once again.  

Pro Tip: Perform a Full Flush Annually

To maintain your water heater’s efficiency and extend its lifespan, it’s recommended to perform a full flush at least once a year. Regular flushing prevents sediment buildup and ensures that your water heater operates at peak performance. Additionally, an annual flush reduces the risk of corrosion within the tank, which can lead to leaks and other issues.
