How to Empty Water Heater Safely and Effectively
How to Empty Water Heater?
To empty a water heater, start by turning off the water heater and allowing the water to cool for a few hours.
Then, turn off the cold water intake valve and run hot water from a faucet to empty excess water from the pipes.
Next, open the pressure relief valve on the tank and connect a long garden hose to the drain valve on the water heater.
If the water heater is above ground, let the water drain out through the hose to an outdoor location.
If the water heater is below ground, use a pump to pump the water up through the hose.
Remember to follow safety precautions, such as wearing heavy-duty rubber gloves and safety glasses, and locate the main water shutoff valve in your home in case you need to stop water flow.
Regularly draining the water heater every 6 to 12 months helps remove sediment and buildup, improving its efficiency and saving energy and money.

Cooling And Shutdown
To ensure the safety of the process and reduce the risk of burns, it is imperative to allow the water heater to cool down before attempting to drain it. Start by turning off the water heater at the breaker panel or the on/off switch typically located near the unit.
It is essential to give the water time to cool, which typically takes a few hours. Rushing this step could result in scalding hot water spewing out during the draining process, causing severe injuries. Always prioritize safety when dealing with hot water heaters.
Excess Water Removal
Before draining the water heater, it is essential to remove any excess water from the pipes. Start by turning off the cold water intake valve that supplies water to the heater. Once this is done, turn on a hot water faucet in your house to allow the excess water in the pipes to flow out. This step ensures that there is minimal water left in the system, easing the draining process.
Opening The Pressure Relief Valve
The pressure relief valve is an essential component of the water heater that helps prevent excessive pressure buildup. To release any remaining pressure inside the tank, it’s crucial to open this valve before draining the heater. Locate the pressure relief valve, usually positioned towards the top of the water heater, and carefully lift the lever to open it. Caution should be exercised as hot water may erupt from the valve.
By opening the pressure relief valve, you allow air to enter the system, which facilitates the drainage process. If you face any difficulties operating the valve or notice any faults, it is advisable to consult a professional plumber for assistance.
Connecting The Drainage Hose
Before connecting the drainage hose, ensure that the water heater is completely turned off and that the water inside is cool enough to handle. Once this is confirmed, locate the drain valve on the water heater and attach a long garden hose to it.
The hose should be securely fastened to prevent any leaks or spills during the draining process. Make sure the other end of the hose is positioned at an appropriate location for water disposal. It is best to drain water outside if the water heater is located above ground. If the water heater is below ground level, additional steps are required, as discussed in the following sections.
- Turn off the water heater completely before connecting the drainage hose.
- Ensure that the water inside the heater has cooled down before proceeding.
- Locate the drain valve on the water heater.
- Attach a long garden hose securely to the drain valve.
- Position the other end of the hose for water disposal.
- Prevent any leaks or spills by securely fastening the hose.
- Drain water outside if the water heater is above ground.
- For water heaters below ground level, follow additional steps discussed in the following sections.
Note: Additional steps may be necessary for draining a water heater below ground level.
Draining Above-Ground Water Heaters
For above-ground water heaters, follow these steps to properly drain the water:
- Connect the hose to the drain valve.
- Open the valve to start the draining process.
- Allow the water to flow freely through the hose and direct it to an appropriate outdoor location, such as a drain or a garden.
- Monitor the draining process as it may take some time, depending on the water heater’s capacity.
While draining the water, take the opportunity to inspect the drained water. If you notice excessive sediment or debris, this indicates the need for a thorough cleaning of the water heater. Sediment and buildup can reduce the heater’s efficiency, leading to increased energy consumption and higher costs. Therefore, it is recommended to clean and drain the water heater every 6 to 12 months to prevent these issues.
Draining Below-Ground Water Heaters
If your water heater is located below ground level, draining it requires additional steps. Simply opening the drain valve may not be sufficient to remove the water effectively. A pump is necessary to elevate the water up to ground level and through the hose for proper drainage.
Connect the pump to the garden hose and lower it into the water heater. Ensure that the pump is submerged in the water to guarantee effective operation. Once everything is set up correctly, activate the pump to begin the drainage process. The water will be pumped up and out, following the path of the hose, until the water heater is empty.
Remember to monitor the drainage and make sure the water is flowing smoothly. Once the water heater is empty, disconnect the hose and remove the pump. Properly store both the pump and hose for future use.
understanding how to safely and effectively empty a water heater is crucial for its maintenance. Regularly draining the water heater helps remove sediment and buildup, improving its efficiency and saving on energy costs. By following the steps outlined above, you can ensure a smooth and safe drainage process, whether your water heater is above or below ground. Remember to prioritize safety by allowing the water to cool, wearing protective equipment, and consulting a professional if you encounter any difficulties.
Frequently Asked Questions
Do you need to drain your water heater completely?
Yes, it is essential to drain your water heater completely. However, simply draining it is not enough. To properly maintain your water heater and prevent any issues, it is recommended to drain and flush it twice a year. By doing this in the spring and fall, you remove minerals and sediment that can accumulate over time, ensuring optimal performance and longevity of your water heater. Regular maintenance is crucial to avoid potential problems caused by the build-up of minerals and sediment.
Can I drain my hot water heater by myself?
Yes, you can certainly drain your hot water heater by yourself. To do so, you’ll need to locate the tank drain valve near the bottom of the tank and attach a standard garden hose to it. In some cases, there may be a cover over the valve opening that you’ll need to remove. Once the hose is securely attached, you can place the other end of the hose in a floor drain or on a driveway where the water can safely drain.
Is it safe to drain your hot water heater?
Yes, it is safe to drain your hot water heater after allowing it to cool down. Allowing the water heater to sit overnight or for a few hours ensures that the water inside the tank has cooled down sufficiently to minimize the risk of potential injury. Taking a hot shower before draining the water heater can also help in accelerating the cooling process. Prioritizing safety measures and following these steps will help ensure a safe and successful draining of your hot water heater.
What are the steps to properly drain and empty a water heater without causing any damage?
To properly drain and empty a water heater without causing any damage, follow these steps. First, turn off the electricity or gas supply to the water heater. This will prevent any heating elements from activating while the tank is empty. Next, locate the drain valve at the bottom of the tank and attach a garden hose. Ensure the other end of the hose is positioned in a safe location to prevent any damage or flooding. Open the drain valve and allow the water to flow out. Once the tank is empty, close the drain valve and remove the hose. Finally, turn on the cold water supply to the tank to flush out any remaining sediment before turning the electricity or gas back on.
It’s crucial to follow these steps carefully to avoid damaging your water heater. Failing to turn off the power source can cause overheating and potential harm. Additionally, make sure the drain valve is fully closed and the hose is properly positioned to avoid any water leakage or flooding. Regularly draining and flushing your water heater helps to extend its lifespan and maintain its efficiency.
