How to Drain a Water Heater

Let the Water Cool Down

Hot water can cause scalding hazards, so you need to wait for the tank water to cool down before draining your unit. After turning off the power, wait at least two hours before draining your unit. This is crucial for safety, as the water inside the tank can still be very hot right after the power is turned off. If you're in a hurry, consider working with a professional plumbing repair service to speed up the process.

Attach a Hose to the Drain Valve

The drain valve is often located the bottom of the heater. Once you find it, attach a garden hose to direct the water away from your indoor spaces. Place the other end of the hose in a bucket or lead it to a floor drain. It is essential to ensure the hose is securely attached to avoid any leaks which could cause water damage. This simple step provides a clean and controlled draining process.

Open the Pressure Relief Valve and Drain the Tank

Once you attach the hose, open the pressure relief valve near the top of the tank. This allows the air to flow into the tank as the water drains, ensuring smooth flow. Depending on the size of your water heater, this can take a few minutes to half an hour. If you notice sediment coming out with the water, this is the buildup you're trying to remove.

Flush the Tank

After the majority of the water has drained, it's a good idea to flush the tank to remove any remaining sediment. Turn on the cold water supply for a few moments while the drain valve is still open to eliminate lingering debris in the bottom. Repeat this process several times, if necessary, until the water runs clear. If you prefer a hands-off approach, schedule a flushing session with a professional plumbing service provider. A plumber can inspect your unit for signs of deterioration and recommend solutions before refilling the tank.

Refill the Tank and Restore Power

Close the drain valve and disconnect the hose. Next, close the pressure relief valve and turn the cold water supply back on. Let the tank fill before restoring power to the water heater. For electric models, switch the power back on at the breaker box. Turn the gas control valve back to the "on" position for gas models. It's essential to ensure the tank is full before turning the power back on to avoid later damages and costly water heater repair emergencies.
