Most consumers only think about their water heater when it stops working. To extend the life of it, you should drain the tank annually to remove any sediment that may have built up inside. Below are steps to drain your water heater and ensure it continues to work properly throughout the years. Be sure to always read the manufacturer’s instructions and warnings first to prevent damage. If you have questions or prefer a licensed plumber, call Mike Wilson Plumbing for all your plumbing needs at (804) 641-6570.

4 Steps To Drain Your Water Heater

Step 1: Turn Off Your Water Supply

If you are using an electronic water heater, turn off the power at the breaker. If you are using a gas water heater, turn the thermostat to the “pilot” setting. Use a hose and connect it to the drain valve located near the thermostat, but do not open the valve. Turn off the cold water supply that feeds into the water heater.

Step 2: Drain the Hot Water Supply

Open one of the hot water faucets in one of your sinks or tubs. This will prevent a vacuum from forming in the lines. Go back to your water heater and open the drain valve to drain the hot water out. You will want the far end of the hose to drain somewhere that won’t be harmed by the hot water like an outside driveway.

Step 3: Flush the Remaining Sediment

Once the water stops flowing out of the far end of the hose go ahead and turn the water back on. This will remove any sediment out that is left behind in the water heater. Once the water is running clear from the end of the hose, close the drain valve. Turn the hot water faucet back off.    Some water heaters may need to be completely full in order to prevent damage. It is best practice to read the warnings and manufacturers instructions on your water heater first prior to draining.

Step 4: Test Pressure-Release Valve

Turn the power-supply to the water heater back on after the tank is filled with water. Once the temperature has been brought back up, test the pressure-relief valve according to the manufacturer’s instructions. This device is designed to prevent excess pressure build-up or overheating inside the tank. If it’s not working properly, you may need to have it replaced by a licensed plumber.
